Wrist mount fish finders

[jvox]

Anyone ever use the fish finders that goes on a line and has a display on your wrist like a watch? Im curious to know how well they perform. I Fish from shore most of the time, and sometimes on my kayak. I think this would be a great thing to have if it works. Hopefully someone has used it!!

I have tried it.  I didnt like it very much.  

Your better off tieing on a crankbait and using that to search the bottom structure.

If your primarily going to use it on your kayak, Id get a regular depth finder for it.  There are different variations that you can look into for use on the yak.
