Bought E5DSI unit yesterday and have not installed yet. Concerned about many of the reviews I have been reading. One in particular discusses the unit at low to no speed. See below review from BPS site:

"Most people that have problems with this unit dont understand how this product works. You have to be moving at least 12 knots or 8 mph for optimum efficiency. At that speed this product is great, so no you cant sit over top of a rock pile and count the fish down there you must be moving for it to work."

I fish mostly shallow water, 10-15'. Sometimes as deep as 20-25. Always for crappie. Also use trolling motor when I get to my brush and/or drop-off's, or while searching new areas for brush. Concerned unit may not read properly??

Beginning to feel I just need a 2d unit with GPS feature. DI is questionable at this point because of the above as well as fear of the very small swath I will recieve in the shallow water I fish.

Thoughts/comments appreciated!!

Thanks,

Dan.
