True, the electronics for determining a magnetic field draws relatively high current. In addition, the unit has to be kept fairly level to be accurate, which is quite hard, if not impossible in a moving kayak. By the way, my eTrex Vista runs for well over a day on a pair of 1800 mAh NiMh cells (Magnetic compass and WAAS off and in battery saver mode).
