Go where photography is headed with the Promote GPS! Now photographers can harness GPS technology to pinpoint the precise location from which a photograph is taken. Called "geotagging", this new technology embeds geographic information into a photograph along with the time and date stamp.
The Promote GPS Receiver features the SiRF Star III chip, which excels at acquiring and maintaining a GPS signal lock.
