Got a new depth finder this weekend. Used it a little on Saturday and I'm thoroughly impressed with the GPS side of it. The color sonar is gonna take some getting used to though. I'm gonna have to remount the transducer about an inch lower as it's coming out of the water as speed increased past 15 MPH. One thing I'll say for it. The speed display for the GPS matches almost exactly my speedometer that's on the dash. I'll post more info about this unit as I get aquainted more with it.
