I have the same unit, but it's a knockoff made by Anysun. It's great for scouting , finding depth and bottom composition.
Downside is low vision in murky water an getting a line tangled in the cam line if ya jig too deep. I have had a couple of pike naiil the cam cause it looks like a decoy.
The depth/temp. display on my unit is in metric, have you found a way to display standard?.
Overall for the 100.00 i spent I'm happy w/it.
I heard there was a. remote type 360 degree panning kit you can add for 70 bucks, if you're fishing clear water that would make a great kit.
