We don't normally get very excited about things that involve scary things like nature, bugs, and sunlight. In this case, though, DeLorme's Earthmate PN-40 GPS device sports some seriously interesting features that we couldn't pass up. It uses a high-sensitivity 32-channel Cartesio chipset that speeds up signal acquisition, a dual-core processor for insane redraw speeds, 3-axis compass with accelerometer to allow use in any position, 500MB of internal Flash memory, and supports SDHC cards. Phew. So there you have it, one of the most intense GPS units of doom you can possibly get. Good luck out there, nature people!
