That's pretty slick, Don.
So you have a battery in the box, ...and what do you do with the transducer?
Kingbass, take a look on Amazon for a handheld portable.
I forget the name of it, and I'm too lazy right now to go find mine,
but it was about $50 bucks and will definately show you depths, and more.
I'll look for mine...
Man I gotta get organimizized...
Here's the link;
I bought one last fall, and used it (really just kinda checked it out) once on Lake Wisconsin.
Seemed to work well, depths were right on to what the guide's $3,000 Hummingbird were showing.
While standing on a bridge and lowering the transducer, it showed fish moving through the area, which I thought was probably accurate since this bridge area was the most productive (and heavily pressured) area on the lake.
Pretty neat little item.
As I like to say to justify my purchases - "I've done dumber things with fifty bucks before."
In light of the fact that the earth is 2/3 water and 1/3 land, it is clear that our time should be divided. 2/3 fishing and 1/3 work.
