You can get some lithium ion rechargeable batteries out of china, pretty expensive, 50 dollars for two AA's. They last 12hrs and have consistent power for all 12hrs in cold weather. Of coarse if you want satellite with any of the handheld gps you are going to have to purchase a subscription for around 30 dollars each year, garmin is just a bit more money than magelllans, the screens are really small with slow download speeds. I just use a tablet now with a built in gps with two apps which are Memory maps and google earth, battery life is incredible and clarity is unbelievable, nautical charts are also available. For that a laptop using globalsat bu-353-s4 usb gps connection which is windows 10 compliant. Pilots the tablet works just fine.
Question?
What do you mean by needing a subscription for satellites on a handheld gps unit.?
I'm a surveyor and been running gps for years. Be it for work ( base and rover ) or personal hand held units and never had to purchase a subscription on any of it.
