results from garmin160c drove 50mi to ky lake to try it out and get the transducer adjusted on 14/ jon boat. Got there and took it out and !!!!! it would not work!! Crap another dud. Drove back to Paducah and bought another battery and fuses and go back to lake and try again. Success! amazing how a charged battery helps power a unit. Scooted around the lake(if you call scooting with a 6hp 14' boat "scooting". Adjusted the transducer and played with the unit. I LIKE the color as I was able to tell hard rocky bottom from soft bottom well. played with the gain a bit but still dont know much how that works. Tried out the dual range transducer and I think that will be a big help in the shallow lakes(under 8' deep) that I fish. Overall I thiknk i going to be happy with this. This is my very first experience with any type of fish finder...lot to learn.
