Other features include a built-in temperature display, Advanced Fish I.D.™ and ASP™ noise rejection. 1,500 watts of peak-to-peak power.

mostly satisfied, September 11, 2009
By rockbottom

"Not a T. motor transducer , as advertised, but a skimmer transducer w/T. motor bracket. Easy mounting if you have done this type of thing before. fish symbols very tiny, as with most of this Mfg. Having some display blockage on the far left of the screen. corrected by rebooting.not a broblem at this point. Have only used this unit about six times."

Great Unit, May 5, 2009
By tobrits from Kersey, PA

"This unit came with such outstanding user-friendly installation directions that the install was a snap. The instructions are well written, and easy to understand...

I have only used the unit once on the water so far, but it powered up easily, quickly, and the menu's were simple to follow. The display was easy to see from anywhere in my boat. I am sure this unit will rate a 5-star after I become more familiar using it....Great product!!!

Fishmark 640C, October 21, 2008
By chaunc from Sharon, PA

"Has a very good number of pixels but the screen seems too dark when trying to view it with polarized glasses. I'd tell a friend this before i recommend them getting one. Also, this unit isn't better than my 480. Only diffrence to me is it's a color unit."
