Locations to practice Land Nav around Eglin/7th group complex?

[Game Trained]

Howdy all,

I'm currently at school for EOD in eglin, and I need to brush up on my land nav. by the 27th of april. I was curious if there is a location that other soldiers can use on/around the SF complex to practice things like the star course in SFAS?

If not, is there a location that any of you recommend?

Also, where would I find a place that sells/rents (preferably) compasses and maps of the area?

Thank you.
