Fish finder problem.

[momodig]

I have a cuda 300 (not the best fish finder but it did do it's job). Anyway, lately, the 7 pin connector (I think it's 7 pin, don't remember) is very touchy. If I just the cables, the unit would power down.

After examining the cables, I notices some of the pins were badly bent. So I straightened them the best I could. The unit now powers back up, and so far it doesn't appear to shut of if I touch the or bump the cables.

My question is. I did the repair on the fish finder at home... when I plug in the sonar (not in water) nothing appears on the screen... ie, ground/arches and the depth seems to be fix at a 53 FT. Is my sonar ruined? or do they usually not work out of water. I'm not going to be at a lake this week to test it... but would like to know if my finder is broke before I go fishing.

Thanks...

The tramnsduser dose not work out of the water.

It dose not hurt them to take them out of the water, they just dont work that way.

stick it in to a five gallon bucket to make your test. you dont need a fish, a balloon tied to a large peice of iron or rock will work for a fish.

with out the balloon it should tell you the depth of your bucket.
