Each card consists of a micro-sd card and a regular sized SD card Adapter so it will work in both your laptop and your gps device.
We also build custom SD cards for your hike which include tracks, waypoints, and maps. We can custom program your GPS if you find all this too puzzling.

If you do not have the needed software, hardware, or patience to program SD cards for your hike, we will do it for you. If you have a GPS that will accept SD or Mini SD cards, then these preloaded cards will make it easy. Before ordering, you need to figure out how many waypoints your GPS will hold. If it has a 1000 waypoint limit, then be sure to order the appropriate cards. If it has a 2,000 waypoint limit, then fewer cards are needed. Cards are also available with POI's instead of waypoints. The entire CDT database of over 7,000 waypoints will fit on a single card in POI format.
