Geotagging Comes To High-End Nikon Cameras

The world is quickly getting smaller and smaller, and one prominent area that’s helping this cause is geotagging, a GPS-based technology that adds location information to images and information posted online. The downside? Well, devices need to have GPS-aware technology, and even in today’s iWorld that’s still not ubiquitous. The GP-1 dongle changed that for Nikon DSLR users. The device fitted into the camera’s hot shoe, adding GPS capability to an otherwise location-unaware camera. Accessory maker Gisteq has one-upped Nikon with the PhotoTrackr Plus, a similar device that connects to your Nikon’s 10 pin terminal and transferring geo-data via Bluetooth, freeing up your hot shoe for it’s intended purpose, holding your flash gun. Nifty! The PhotoTrackr Plus costs $179 and works with both JPEG and Camera RAW workflows. Source: Ubergizmo
I prefer my Eztag for that one main Bluetooth devoice could work with my D300s and D7000 at same time.
I wonder if $179 is the price for GPS devoice and Bluetooth receiver? Or only for GPS devoice?
It seems really smaller, but the function is common. How does that power supply? Does it have independent battery like Easytagger does? If not, I would rather use my Easytagger.
$179? No thanks. You can do the same thing with a $30 GPS logger from eBay, and the excellent freeware program GeoSetter.
