The Magellan GPS 310 is an affordable 12-channel global positioning system receiver with an NMEA 0183 output for downloading map data from optional CD-ROMs via your PC. This GPS unit's quadrifilar antenna locks on to satellites for accurate positioning in all kinds of terrain.
View your navigation information on any of three graphic screens with a powerful backlight for dim conditions. Other GPS features include 100 waypoints, one reversible route with 10 legs, and a resettable trip odometer that tells you how far you've traveled so you can estimate the time you need to start back. Distance, bearing, heading, direction, steering, speed, time to go, elevation, XTE, time, and satellite elevation are all displayed on the high-resolution LCD screen. Tough rubber armoring protects this unit in the field, and waterproofing allows it to float.
The GPS 310 runs on two AA alkaline batteries for up to 20 hours. It comes with a wrist strap and quick-reference guide. It is covered by a one-year warranty.

I ran through the setup and set it up for my home residence then made the first landmark, or waypoint to my home address. I also looked up the coordinates of the town I live in on Wikipedia and the numbers came up on the unit exactly as reported in Wiki.
Update 11/16/16: I cranked up the GPS this morning after putting in newer batteries and most of the malfunctioning lcd's are now working. Could have been a lower voltage issue using renewable NiMH batteries. They were charged just before installation but may not have been fully charged, Today I will give this little dude a road test. I will take it to the woods when I hunt again. Now I like it a little better. (the 4 stars is for the unit. I left out the last star because of the difficulty in contacting the seller. But, if I order from them again I may have an extra star for them. )
I only need this GPS so I can find my way out of the woods. I usually hunt and hike the sane area but I did get turned around once this year. I had not been there for 3 years and everything changed a lot and I got confused. But the landmarks I chose for such a case were still in place so it was easy to get back to the car. It was a long walk but I made it. This little GPS would have saved me many steps and I am happy with the purchase. Next will be data cables if Magellan tells me there are software updates available.
The manual is overly pessimistic in regard to the time the unit takes to "fix" a location. The manual says 2 to 5 minutes for a location fix, but I get a "lock" in 30 to 50 seconds most of the time. Sitting on my sofa, in front of a window, the unit obtained a postion fix in 45 seconds with the venetian blinds only partially open. Venturing into a desert canyon the unit performed even faster. With most of the horizon blocked by the canyon walls the 310 locked in a postion fix in 30 seconds.
The 310 also performed well in a moving car, with the unit propped up on top of the dashboard. In the moving car the 310 maintained a lock on enough satellites to register speed of travel and a working "North" arrow.
It doesn't have the bells, whistles, moving maps, etc. of the higher priced units, but it does what I wanted it to do when I bought it.
When I hooked the Magellan 310 to a laptop computer with a serial cable, the 310 outputs up to 6 digits of Minutes - more than sufficient for any task. So if you're looking for a bargain priced GPS receiver for use with a laptop for something like NetStumbler or DeLorme Street Atlas, I think this is a good bargain if you can find it under $50. Be sure to budget for extra cost of a serial cable (about $20) as the cable is not included.
Unfortunately, you can't transfer saved waypoints between your computer and the 310 with the serial cable.
I also think this GPS receiver is perfectly suitable for situations where high precision isn't required. For example, finding your way back to your car after hiking in the woods doesn't really require 3 Meter precision like modern GPS receivers have - the Magellan 310 should get you within 20 Meters (about 65 feet). That should get you close enough to see your car.
One of the most popular reasons for buying a GPS receiver is for geocaching. Most people that want to try out geocaching look for a low-priced GPS receiver so they can try the sport and decide whether or not they like it. While it might be tempting to buy the Magellan 310, I strongly suggest spending a few more dollars on a GPS receiver with 5 digit minute precision like the Magellan 315 or the Magellan Sportrak. It is technically possible to geocache with the Magellan 310, but you'll have to manually adjust for the 4 digit minute precision. Explaining how this adjustment works is beyond the scope of this review, but trust me when I say you want something better than the Magellan 310 for geocaching.
