Our Verdict: Garmin GPSMAP 66sr Multi-Band Handheld

Multi-band accuracy in a proven button body, ideal for hunters who need a precise, rugged unit.

A button-operated multi-band handheld with a rechargeable internal battery, tuned for the accuracy hunters and geocachers want in rough terrain.

So, is it any good?

Multi-band and multi-GNSS across GPS, GLONASS, Galileo and QZSS.

Multiple frequencies improve accuracy where signals reflect off rock or filter through canopy.

It puts me on a mark in thick timber better than any AA unit I have carried. The catch is the sealed battery, so on long trips I am hauling a power bank instead of a fistful of AAs.

Classic GPSMAP button layout that works with gloves and in wet weather.
