Bluetooth GPS recievers are not so much a brand of GPS recievers but more of a class. They come from many different manufacturers, but they all have the ability to communicate with other devices wirelessly using bluetooth technology. Usually a bluetooth gpsr simply sends a stream of coordinates across it's bluetooth link to the listening device. The listening device could be a PC, a PDA or a laptop. Bluetooth gpsr's usually do not have a screen, or memory, and only an on/off switch. The benefit of this is usually a great deal on a powerful GPS chipset. If you cache paperless with a bluetooth-enabled PDA, or laptop, this could be a great option for you. Basically, you would perform any mapping, navigation or plotting functions on the other device, with your GPS being used simply as a source for your current coordinates
