I beg to differ on the One-Boat Network app, I was on a lake yesterday in 30′ of water and One-Boat Network showed 11′. Also, the current location marker keeps moving around just standing still.

Did it look something like this?

Anybody know what the rain and warm weather has done to the ice?

Thanks, I will research again. Does anyone charge their lithium with the lead acid chargers?

I hear everyone saying how light these are, the lithium batteries claim to be 7lbs while the lead acid claim to be 5lbs. Which is true?
