Very true. I keep mine on "auto" for depth but I'm using it at the helm and not the trolling motor.

I drop shot up to 30ft at times becasue I'm on a highland reservoir with clear water so sometimes, 15-25ft is the depth the fish relate to becasue the water is clear. If I go up near the dam, they may be 30-35ft deep simply because you can see down 20ft easily the water is so clear.

If he wants GPS and a quality sonar, this is a good unit. I jus tdon't want someone thinking (as I did) that it's the newer super hi-def structure scan units like the HDS units. I now know that they have the external modules and the technology that supercedes the Elite 5 units.

I got mine for $299 at this year's Bassmaster Classic and I think I paid about what the unit is worth. I wouldn't pay over $350 at this point after I have used the unit more. I like it, don't misunderstand. But after using an HDS 8 on the same lake in someone else's boat....there's just no comparison however...........the PRICE difference between the Elite and HDS is WAY different and not an apples to apples comparison by far.

So......all in all it's a good unit if you can get a good deal one.

Oh....and mine came with the trolling motor mount. So check to see if the unit comes with this before buying the accessory.
