I enjoy reviewing GPS photo tagging gadgets here on The Gadgeteer, so I will be interested to see how ATP’s latest PhotoFinder device compares to their previous models. They are hailing it as the answer to Sony’s GPS-CS3KA. The PhotoFinder Pro does sound like it has the upper hand due to the fact that it can support an external battery pack, external GPS antenna, POI (Point of Interest) recording. It will be available at the end of July for around $119.
