Electric Downriggers

Downrigger

Can you explain how the auto surface feature works without there being any connection between the cable and the controls?

The only time that it turns off is when the last part of metal comes out of the water.

Also you stated that when you switched away from cable that the auto up feature stop working all together.

Wouldn't the points make it seem that there is a electrical circuit being used somehow?

[Downriggerer]

Sorry for the slow reply.  Work has been dawn till well after dusk the past couple days. I'm not sure how they do it.  My guess is that since the spool is set back further into the downrigger, they are using an inductor to put a voltage on the wire.  And, the auto-up feature detects when the ball is in the water by watching what the ground is doing relative to the boat.  If you hook up a cannon downrigger to a battery that is otherwise disconnected from the boat ground, the auto-up feature is disabled.  In fact, that's how I disabled the auto-up before installing the Scotty electrical connectors and the braided downrigger line.  I would assume, but can't be sure, that disabled the "Positive Ion Control" as well, or at least made whatever voltage they are trying to put on the downrigger cable short to ground.  So, between that and the math telling me that electrical fields don't propagate well under water, I'm skeptical that the PIC or black box works.  I think, and the math says, it catches fishermen, not fish.

DUDE - you are one hard sell!    

First of all, it ain't 'math'; it's physics.  My college professor would have smacked your knuckles HARD for not knowing the difference in his classes.    

Let's define what an ion is.   Ions are particles that have an electrical charge because they have lost or gained an electron.  Pure water has NO ions in it.  But there isn't any lake in the world that doesn't have impurities in it, and some of the impurities are in fact ions and it's these ions (impurities) that allow current to flow through water.  Water that is 100% pure - nothing but hydrogen and oxygen - will NOT conduct an electrical current.  Period!

I have no idea how far kokanee can sense a positive ion charge, but scientific research has determined that if two AA batteries were connected 1,000 miles (1,600 kilometers) apart, a shark could detect if one ran out.  I can only guess at this point, but believe that kokanee can probably sense the positive ion charge hundreds of feet away from it's source.

Cannon describes PIC this way:

This feature is based on the principle that applying a low voltage positive electrical field into the water where you’re fishing will attract fish and increase your chances to catch more fish. Since fish are attracted by a slight positive charge and repelled by a strong positive or negative charge, generating and controlling the correct charge can be critical to the success of your fishing. With Cannon’s exclusive Positive Ion Control you can change the natural negative field created by the grounded electrical system of your boat to a positive field. More information on how fish respond to electricity can be found in The Secrets of Fishing with Electricity by Ollie Rode.

Cannon describes Short Stop this way:

Short Stop is a Cannon exclusive feature that automatically stops the weight at the water’s surface, preventing the lift motor from raising it into the pulley at the end of the boom. When the downrigger cable is in the water, a small electrical current flows between the cable and grounded metal boat components in the water. When the cable clears the water, the current flow stops. The short stop system senses this interruption and turns off the motor. The trolling weight insulator is used to break the cable contact to the water while the weight is still in the water. Stopping the weight at water level eliminates the cable strain caused by a bouncing weight or a weight hitting the boom end and it also keeps the weight from swinging into the boat hull. This feature comes on all Cannon electric downriggers and requires the boat to be properly grounded.

Cannon describes what happens to both when you replace the metal cable with braid/mono:

Both of these features rely on the stainless steel cable to conduct an electrical current into water. Since monofilament and superlines will not conduct an electrical current, these features will not function when the downrigger is re-spooled with them.

When you wired your Cannon directly to a battery that wasn't ground to the boat, you essentially eliminated the current path through the water back to the negative side of the battery and neither of the functions would have worked.  However, if you had measured the voltage between the cable (before you switched to braid) and the negative terminal of that isolated battery, you would have seen a 0.6 vdc differential between the two.

There are lots and lots of ion particles in lake water.  The technology to control the voltage level configuration of those ion particles is real and it ain't math - it's physics.  There is a ton of material out there that explains it to us uneducated folks.  I can explain it to you until the fish bite, but I cannot make you believe it if you refuse to do so based on scientifically documented studies saying it is true.

Hodges Marine out of Florida has the best prices on downriggers that I found and they sell both Cannon and Scotty brands.  The Cannon Mag 10 & Scotty 1106 are both right around $530 each and they have free shipping to the lower 48.

I think I'm done here.  The OP should have enough information to make a decision on which brand to buy at this point.  Y'all take care, stay safe, and tight lines.

Bob, you can't "do" physics.  You can do the math that explains the physics.  You know good and well that physics doesn't mean anything without the math to explain it. The physics is the concept.  The math describes it.  Saying that it's "not math, it's physics" is disingenuous and you know it.  

And no one has argued that water doesn't conduct electricity and the more free conductive minersals in it, the more electricity it will conduct.  But you are talking about running .6v down 40-80 feet.  The electrical field that creates is virtually zero, like approaching zero as the limit of the water's conductivity approaches infinity.  That's less than your two AA batteries, which I might also note is a test run in salt water with sharks, which is more conductive than water in lakes, for the most part.  Whatever field there is, is gone, real quick.

The reality is that my downriggers were not directly electrically connected to anything when I took the steel cable off.  That can't be argued.  There were no connections between the electronics in the downrigger and the cable.  That's not to say that an inductor or a magnet couldn't be in the downrigger body itself.  But, there is no direct connection. 

As I said, even assuming that there is electricity on the cable, their explanation is plausible for how the auto-up works.  The auto up is also defeated NOT JUST BY SUPERLINES but also by using another battery NOT CONNECTED TO THE BOAT's electrical even with the stainless steel cable.  Fact.  It's how I've run my boat for years, specifically to defeat the auto up.  And it is likely because I shut off a negative return through the water.  But, again, so what?  That doesn't change anything I've said.

The bottom line is that I catch hundreds of kokanee a year.  I have shown people on this forum how I do it.  I built my own rods to make a better fishing experience and to land more fish.  I make my own lures.  I have specific hook setups that result in more fish in the boat.  I have caught them with and without the "positive ion control" nonsense.  I have caught them with superlines and without superlines.  I have caught them pretty much every way there is to catch them and I usually have to quit catching them before I'm done catching them because I have limits already.

Everything in my fishing experience says having 2 more lines in the water on a stacker FAR outweighs the value of whatever voodoo electrical nonsense.  Everything in my electrical experience says Positive Ion Control catches fishermen, not fish.  And, painting my downrigger ball with the superlines has resulted in no change to my fishing success either in terms of the number of hits I get or the number of fish in the boat. 

Cannons are generally available in utah at the sporting goods stores.  That's why I bought mine.  But that doesn't make them the best downrigger, which is a mistake I made in buying them. 

I made my case.  The OP can do whatever he wants.  But, at least through this process he can see the pluses and minuses of each type of downrigger.

Oh hogwash. Physics is the scientific study of matter and energy and the relations between them. Nobody needs to use math to understand the relationships; they only need math to define or measure the relationships. In the case of the PIC, one only needs to know that controlling the ions to a desired level (in this case + 0.6 vdc) is better than a negative voltage or a significantly higher positive level. I don’t have to do any math at all to know and understand that concept. And neither do you. Show me one single bit of math that you were required to do to understand that principle.
And no one has argued that water doesn't conduct electricity and the more free conductive minersals in it, the more electricity it will conduct. But you are talking about running .6v down 40-80 feet.

That's less than your two AA batteries, which I might also note is a test run in salt water with sharks, which is more conductive than water in lakes, for the most part. Whatever field there is, is gone, real quick.
I don’t care how much cable you let out – the voltage you measure between the cable and the boat will be + 0.6 vdc with the Cannon PIC. And you don’t have a clue as to how big the electrical field is or how far away any species of freshwater fish can detect/feel/sense that field. If, by chance, I’m incorrect and you do have a clue, show me your math that shows me exactly how big the electrical field is an how far away a kokanee salmon can detect that specific field.
The reality is that my downriggers were not directly electrically connected to anything when I took the steel cable off. That can't be argued.

It ain’t voodoo electrical nonsense. The electrical current flowing through the water produces an electrical field around the current flow and perpendicular to the direction of the current flow. This is a condition of the physical world we live in that is measurable. Its already been proven and requires no doing of math by any of us. I know it exists without doing any math.
I, too, ran braided line on my previous Cannon downriggers to eliminate the cable hum. I had no trouble at all catching limits of kokanee at the Gorge and Strawberry using braid. When I bought my new boat in 2017 and ran 4 Scottys on it, I found a voltage level of +0.9 vdc measured between any of the 4 cables in the water and the boat. Still caught salmon, but it took longer, on average, to catch a boat limit. It was taking me 3 hours or longer to get a 6-fish limit at the Gorge when friends using Cannons and essentially the same color flashers and squids were catching 6 salmon in under an hour. I now run Cannons with SS cable and can catch a limit in 90 minutes or less on good days.
Use whatever downrigger brand you want. It’s a free country and you are the only decision maker when it comes to what you want on your boat. Just stop trying to convince others that PIC and Short Stop offered by Cannon is bull crap and worthless.
Cannons are generally available in utah at the sporting goods stores. That's why I bought mine.
Really? That’s the reason you bought Cannon – because it was available in a Utah store. Ever hear about Internet shopping? You can almost always find stuff cheaper to buy in the Internet than you can in a retail store near you. And you get to buy exactly the brand you want.
But that doesn't make them the best downrigger, which is a mistake I made in buying them.
I made my case. The OP can do whatever he wants. But, at least through this process he can see the pluses and minuses of each type of downrigger.
To the OP – Either downrigger brand (Cannon/Scotty) will work to get your lures down to where the fish are congregating on any day, be it 5 feet down or 150 feet down or any depth between. I’ve run mine as shallow is 2 feet down. Both have features that the other does not offer. Both have cons. They are very close to each other in price. I recommend Cannon as the better choice; he says Scotty fits his style better. If you don’t like what you buy after using it for a season, put ‘em on KSL at the start of next season and sell ‘em. Took me less than 2 days to sell all 4 of my Scottys after one season’s use and sold them for about $75 less than I paid for each one.

You know what Bob, that's embarassing.  I'm embarassed that you think you can do physics without math.  You said you need math to define the relationships but you fully understand those relationships without the math.  You want to "control the ions" with .6V  But, you have no idea what the effect is because you can't do or understand the math.  You can't just shoot .6V into the water and start controlling the ions.  You have no idea how any of this works, or allegedly works.  That's why you are stuck on the prinicple because you can't see the numbers behind what you are saying.  You can't even do Ohm's law with the information you know.  Nor do you know the resistance of stainless steel wire.  Nor do you know or understand the permittivity of water using a stainless steel braided line as a transmission line.  These are fundamental issues that you just gloss over for "principle."  There is a lot of math you have to know to do any of what you are proposing.

And no one has argued that water doesn't conduct electricity and the more free conductive minersals in it, the more electricity it will conduct. But you are talking about running .6v down 40-80 feet. The electrical field that creates is virtually zero, like approaching zero as the limit of the water's conductivity approaches infinity.

If, by chance, I’m incorrect and you do have a clue, show me your math that shows me exactly how big the electrical field is an how far away a kokanee salmon can detect that specific field.

So what is the gradient loss of the field intensity as it is transmitted from the source to the ball?  Have you thought about that?  Or, do you know what that is?  Coloumb's Law and Maxwell's equations say that the electrical field is 1 over 4pi E (permittivity of water) multiplied by the integral of the charge density of the length of the field.  By the time you are 40ft down, your Volts per meter are going to be in the neighborhood of approximately microvolts per meter.  That's 10[sup]-6[/sup] volts per meter.  If you were trying to bounce a signal off a satellite in space, that wouldn't be a problem.  But you are talking about pumping that into water, which has the permittivity of a block of jello.  Actually, jello is probably better.  You *might* be able to attract a kokanee to your field if you hit it with the wire.  But, then, he should have felt the wire coming, no?


The reality is that my downriggers were not directly electrically connected to anything when I took the steel cable off. That can't be argued. There were no connections between the electronics in the downrigger and the cable. That's not to say that an inductor or a magnet couldn't be in the downrigger body itself. But, there is no direct connection. That you are aware of.

Bob, c'mon.  That I'm aware of?  I took the thing apart.  I replaced the cable.  I'm telling you there is nothing electrically connected to that wire.  If you want to be stubborn, just say so.  But if you want to have an interesting discussion, then you can either accept what I said or take yours apart and show me how the cable is electrically connected to something.  But, this is a dumb thing to debate. 

As I said, even assuming that there is electricity on the cable, their explanation is plausible for how the auto-up works. The auto up is also defeated NOT JUST BY SUPERLINES but also by using another battery NOT CONNECTED TO THE BOAT's electrical even with the stainless steel cable. Fact.

It absolutely is bull crap and worthless.  It is voodoo electrical nonsense made to impress people who don't know better.  And I will not stop trying to convince anyone within the sound of my math that it is bullcrap, worthless, voodoo electrical nonsense. You learned the concept of the right hand rule.  Thumbs up.  But, if you can't calculate volts per meter, it doesn't do you much good, does it?  You know it exists but not at what intensity or whether or not it makes any fundamental difference in your fishing. 

There are a lot of other things that can explain why your fishing success went down.  You have to eliminate every other variable, which you did not do and cannot reasonably do to prove that your boat was the problem.

Cannons are generally available in utah at the sporting goods stores. That's why I bought mine.

Yes, I bought them at Sportsmans because I got a deal on them.  They were available, they seemed like they would be fine, and I could mount them same day to go fishing for silvers in the ocean.  So, yes, I bought them here because they were available and I got a deal.  I don't see why that's an issue?  Can I not buy them, find out I don't like them, figure out ways to fix them, and tell people what I did to make them better tools?

But that doesn't make them the best downrigger, which is a mistake I made in buying them.
I made my case. The OP can do whatever he wants. But, at least through this process he can see the pluses and minuses of each type of downrigger.

If you want to save yourself $75/downrigger next year, and you want to stack lines, get a Scotty and never look back.  If you want to put voodoo electrical nonsense on your boat and don't want to stack, Cannons will be fine until you lose the bolt that secures the downrigger to the mount or your electrical connectors corrode and you have to contort them in different ways with zip ties you have on your boat for emergencies to get them to work, kind of, for the rest of your trip, get the Cannon.  Oh, and be sure to order the second rod holder later from Cannon online.  Voodoo electrical nonsense is, but not a second rod holder.

You know what Bob, that's embarassing.  I'm embarassed that you think you can do physics without math.  You said you need math to define the relationships but you fully understand those relationships without the math.  You want to "control the ions" with .6V  But, you have no idea what the effect is because you can't do or understand the math.  You can't just shoot .6V into the water and start controlling the ions.  You have no idea how any of this works, or allegedly works.  That's why you are stuck on the prinicple because you can't see the numbers behind what you are saying.  You can't even do Ohm's law with the information you know.  Nor do you know the resistance of stainless steel wire.  Nor do you know or understand the permittivity of water using a stainless steel braided line as a transmission line.  These are fundamental issues that you just gloss over for "principle."  There is a lot of math you have to know to do any of what you are proposing. . . . . ad infinitum

Yeah, what the heck was I thinking. My 40 plus years working in electronics with 20 of those years as an electronics engineer modifying, testing, evaluating, and programming long range radar systems after getting a Bachelor of Science degree in Electronic Engineering (BSEE) is just meaningless when it comes to your far superior electronic knowledge with regard to the super complex downrigger technology. I am obviously out gunned in this discussion and should have bowed out of the discussion several posts above. My most humble apologies to the OP and any others following this thread for daring to go head to head with a far superior intellect than I. All hail the undisputed god of electronic downriggers; His Royal Highness Downriggerer.  I should probably get my order in today to Hodges Marine for 4 replacement Scotty 1106s before the rush.  I should probably get my 4 Cannons on Craig's List somewhere in the Midwest because it will be impossible to sell them on KSL since we've all been enlightened and shown the error of or ways for daring to use an inferior product on our boats.  Tight lines everybody.  Get those Scotty's ordered soon - before the massive rush that is sure to come.

You know what Bob, that's embarassing.  I'm embarassed that you think you can do physics without math.  You said you need math to define the relationships but you fully understand those relationships without the math.  You want to "control the ions" with .6V  But, you have no idea what the effect is because you can't do or understand the math.  You can't just shoot .6V into the water and start controlling the ions.  You have no idea how any of this works, or allegedly works.  That's why you are stuck on the prinicple because you can't see the numbers behind what you are saying.  You can't even do Ohm's law with the information you know.  Nor do you know the resistance of stainless steel wire.  Nor do you know or understand the permittivity of water using a stainless steel braided line as a transmission line.  These are fundamental issues that you just gloss over for "principle."  There is a lot of math you have to know to do any of what you are proposing. . . . . ad infinitum

Yeah, what the heck was I thinking. My 40 plus years working in electronics with 20 of those years as an electronics engineer modifying, testing, evaluating, and programming long range radar systems after getting a Bachelor of Science degree in Electronic Engineering (BSEE) is just meaningless when it comes to your far superior electronic knowledge with regard to the super complex downrigger technology. I am obviously out gunned in this discussion and should have bowed out of the discussion several posts above. My most humble apologies to the OP and any others following this thread for daring to go head to head with a far superior intellect than I. All hail the undisputed god of electronic downriggers; His Royal Highness Downriggerer.  I should probably get my order in today to Hodges Marine for 4 replacement Scotty 1106s before the rush.  I should probably get my 4 Cannons on Craig's List somewhere in the Midwest because it will be impossible to sell them on KSL since we've all been enlightened and shown the error of or ways for daring to use an inferior product on our boats.  Tight lines everybody.  Get those Scotty's ordered soon - before the massive rush that is sure to come.

I'm not going to treat you with the same disrespect over a difference of opinion, Bob.  But, you clearly have a problem with the math.  I noticed the word "designing" was left out of your explanation of your 40 years of changing parts on electronics.  That's because the Electrical Engineer was doing the math for you and telling you to go test his math out.  A BSEE is a degree in electronics without most of the difficult math that explains the physics of signals, waveguides, electromagnetic fields, and etc.  That's not a knock on you.  But, it's a suggestion that understanding the relationships between measurable aspects of physical phenomena is not the same as understand the math behind them.  Maxwell's equations weren't generated by measuring electrical fields and magnets.  Ohm's law wasn't discovered by a guy with a voltmeter.  They were mathemeticians who derived the equations and then found out that the equations reflected what they saw. 

My complaints with the cannons are clear.  You have addressed few of them but have continually defended the positive ion control based on nothing more than the Cannon's website explanation and thumping your chest about 40 years of electronics experience.  You have addressed none of the mathematical issues I've pointed out with PIC. 

Cannon's support entails mailing your downrigger back to them for service, at your expense, which is significant. No parts are available.  If you lose a bolt on the mount, you have to buy a new mount.  Their electrical connectors are outrageously tight even though the electrical contacts within those connectors are loose.  The contacts also corrode within 3-4 years.  They also have the auto-up feature which is a pain to use when you are stacking lines and will cost you hundreds of dollars in lost stacker releases.  And, to put the cherry on top, a second rod holder is not included with a new downrigger. 

Even if PIC worked, why would I put up with all of the rest of that for a downrigger?  I don't even think PIC harms anything.  All I've said is that I don't believe it does anything. 

So what's the problem?  You say PIC works.  I say it doesn't.  We both catch fish although only one of us gets snarky about the discussion.
