This is a
small puck
type, weatherproof, USB GPS receiver.
It is extremely sensitive using the latest technology.
The Water-Proof USB Mouse GPS Receiver with
WAAS/EGNOS
support, is powered by SiRF
Star III chipset which is a
new-generation GPS chipset that has extremely high sensitivity, lower
power usage and more rapid time-to-fix.
It
works very well even in reduced visibility environment or weak
signal tracking, such as down below in the cabin of a boat.
It is
powered by the computers USB port, so no batteries are needed.
