Though I don't have one I have used them and thing they are a great little unit. Really all that is required for water, field and other usage. If thismodel had an electronic compass I would have bought it when upgrading from my olderGarmin (which featured an electronic compass)without question. I just p/u a Garmin GPS60C but have not had any real field time with it, though like every other garmin I have owned (this will be #3) it is very user friendly andexpect it will be as goodin regards tobattery consumption. IMHO Garmin are the king in handhelds, so I think you choose wisely. G/L and enjoy!
