Since there is no sub-forum for Marine GPS, thought I would try here.
With LakeVu HD ultra, once on a lake you are supposed to be able to set dynamic lake levels. Can't find it under any menus.
1) Anyone know how to find it?
2) My unit is off by 1.5 ft. Can I manually set the correct depth or will it read the depth from my transducer? I measured it with a stick and would prefer to set it to the actual measured depth.
