Not only will it get you to your stand and back, If you use some of the better topo programs, it can get you to your tree even if you have never BEEN there before.
Open your topo program, study and look for funnel zones when concidering travel routes (to/from food/bed)
Make a waypoint on your GPS as to where you want your stand, and download this to your GPS.
It'll take you right to your area, and you can find the best tree in the area to use.
Get a GPS with at least some availible memory for uploading maps (preferable one with removable memory) and one that is WAAS enabled.
Some have electronic compasses..most have compass features that work when you start moving...others have a REAL compass built in.
