Garmin GPSMAP 64, 65, 66 & 67 FAQs

I like the 66sr but the internal battery worries me. What gps is equivalent with replaceable batteries without losing water proof features and shock resistance ?

The closest unit to the 66SR that would take AA batteries would be the Garmin GPSMAP 65S this unit will have the advanced GPS receiver and the capabilities of doing GNSS.
