When our map scouts absolutely need to get a satellite lock and keep it, they depend on this series of exceedingly reliable and easy-to-use units. All Meridians come with a PC cable but require an optional SD card (expandable to 128 MB) to download onscreen topos. Magellan’s MapSend Topo US software ($150) is an excellent addition, offering the best national coverage in high-resolution downloads. The Meridian Gold ($250) is the "basic" model, offering true 14-hour battery life on two AAs. The Meridian Platinum ($400) adds a barometer and an excellent three-axis electronic compass, but at a cost to battery life (10 hours in mild temperatures). The Meridian Color ($400) adds a color screen to the Platinum.
All prices for high-tech items are MSRP. Actual retail prices are often much lower, so shop around.
