RE: NEED HELP ON A NEW GPS
I have a garmin rino 120 as well as an e-trex. Of the two the rino gets better reception then the e-trex but both work very well. I like the control button on the rino better as well. If you log a log of waypoints it is much quicker and easier to use the "joystick" to name spots and enter coordinates then with a simple up down button. I don't know per sey if either will work better in the woods then your 72 as I have no experience with that model.
