Sensitive long

The GlobalSat BT-338 uses the latest generation of GPS chipsets from SiRF, the SiRFStarIII, which is stated to be as sensitive as the SiRFXTrac used in their SD-501 GPS, but without the delay and overshooting issues. It doesnt use up your scarce SD or CF slots and can be used with Pocket PCs, Tablet PCs, notebooks, almost any device with Bluetooth. Having your Pocket PCss Bluetooth radio on consumes approximately 30-50 mA of battery power, meaning it uses less power than would a SDIO or CF type card GPS. However since it has its own battery, it is another thing to remember to keep re-charged, and you have to carry on long trips yet another external charger. It does come with a car charging cable, and I found out that the charger for my HP iPAQ will charge the BT-338 as well.
