I've been trying to do some research on outdoor GPS's but there is simply too many shill reviews and lack of the necessary information.

I was hoping some cunning anons had experiences with outdoor gps.

I like being outdoor alot, but my first 3 months were guided by the polaris (lol primitive i know) then I finally got my compass.

However, I want to upgrade to an outdoor GPS, any recommendations? Also here are a few of my questions.

1.
>I have built 3 campsites, far from civilization. I'm forced to remember these places by memory, is it possible for a GPS to save these places, like a permanent marker?

2.
>Does GPS connection cost money to be uplinked, similiar to phones?

3.
>Does your GPS show detailed view of riverbanks, density of forest, hills?
4.
>Is it possible to put a lock or password on it like a phone?
5.
>Is my gps cordinates anonymous? Phones are known to be easily tracked through triangulation

Any recommendations? Please help, they are so expensive so I dont want to buy one that doesnt work so good and regret it.
