I had a etrex 10 but they dont take maps.
I bought the 20 mainly because it had a much longer battry life than other hand helds in my price range.
You can alter the amount of detail too the point it can be far too cluttered in most cases.
Ive never had issues geting a fix even in ghe kaimais.
The trip computer is fantastic in the little boat ,the maps too when exploring rivers.
It works fine in the landcruiser sitting on tge dash.
My flash galaxy 3 will show my position on google earth in the middle of the bush , but gps eats data $$$ eats battrys FAST and its not water proof and 3 times the price of an etrex20
And take a compass and spare battrys .
I like my stock compass holder thingy ,its mint.![]()
GPS doesn't use your data, its just receiving a signal thats being broadcast regardless (unless the US govt decides to turn it off). If it needed data it wouldn't work without signal. Google maps chews data though!
My battery will last about a day with it using GPS the whole time, but usually I just flick it on for a sporadic fix. Plus mine is waterproof, and seeing as I had it for a phone already the $10 for the app was much less than an etrex.
Agreed that you wouldn't buy a smartphone just to use it for GPS though!
