T&T: Forward Looking Sonar

[Pascal Gademer]

Les

interesting post, maybe technology has improved since the one i had a few 
years back.

So, when you are crawling at idle, or even bumping in and out of gear is 8' 
of water for instance, how far forward of the Xducer do see?  is it really 
enoug to see the bottom shallowing up to say 6'?  or will it only show a 
something more drastic like a rock or ledge
