Hey, Beth, I just picked up this top-model GPS unit
Amazon.com: Garmin Oregon 400T 3-Inch Touchscreen Handheld GPS Unit with Preloaded Topographic Maps: Electronics (since it was on sale and had a rebate) which users say is able to pick up signals even when under forest canopy. My old one from 10-15 years ago sure wouldn't do that. I've yet to give it a try, though. Maybe I need to come visit!
