[font "Comic Sans MS"][black][size 3]I'd have to agree with kd and Gumbo. I run multiple units and multiple transducers with the same frequencies and I get interference. I called Lowrance and talked with their techie and we discussed it at some length. Bottom line, it's pretty tough to eliminate the interference problem.[/size][/black][/font]

[font "Comic Sans MS"][black][size 3]Finders don't need to have intersecting cones to pick up interference. Just look at guys on the ice for example. sonar signals can echo or deflect depending on bottom structure and conditions. I've been on BL and had to move away from my buddies boats over 100ft to eliminate the interference problem. We both run Lowrance and 20 degree tranducers. The cone diameter at 100 feet is only aproximately 35 diameter so no intersection of the cones was taking place.[/size][/black][/font]

[font "Comic Sans MS"][black][size 3]All units claim to have filtering or noise reduction features but the reality is when you turn your filters up, you decrease the unit's sensitivity so filters and noise reduction features can be a double edged sword.[/size][/black][/font]
[font "Comic Sans MS"][size 3][/size][/font]
[font "Comic Sans MS"][size 3]As for the chef's question about running one console mounted unit on two transducers, one up front and one in the back, I have to ask the question. What is your reason for wanting to do this? [/size][/font]
[font "Comic Sans MS"][size 3][/size][/font]
[font "Comic Sans MS"][size 3]Most folks who have sonar on the bow also have bow mount trolling motors with transducers attached in one way or another. They used it in conjuction with those electric motors therefore needing it for their specific purpose, whether its bass fishing and using some sort of side finder or vertical jigging directly over the transducer. [/size][/font]
[font "Comic Sans MS"][size 3][/size][/font]
[font "Comic Sans MS"][size 3]I'm trying to understand, in a smaller boat, what advantages you would have with with dual tranducers and a console mounted sonar unit? Logistically, mounting a permanent transducer in the bow, even a shoot thru, would be tricky. Obviously, an externally mount transducer would be asking to get ripped off. Maybe I don't see the whole picture.[/size][/font]
