Just bought this and plan to use it this week. Does anyone know what "zero" is at. I assume 3700'. So if the water level is at 3635' I should set it at -65.
I also have the navionics app for my iPhone. Pretty nice for $10 but found that using the lake offset for that app is not at 3700'. Iirc I had to max it out at 50' and it was still low compared to the lake level when it was at 3630'.
