I have a Nikon GPS-1 but read postings about Solemeta. The N2 had its own battery but the newest N3 is like the Nikon one & powered from the camera. They seem to work 'faster' & more reliably in cities than the GPS1 but any opinions on whether the N2 with its rechargeable battery & being able just to buy another cable in the event of a different camera or even if the cable gets damages? Are there other differences? I ask because whilst they say less current drain on the new N3 the specs show it the same as N2,60mA. If this is the wrong forum for such a question, sorry. Point me in the right direction. Tom
I can only speak to the Solmeta GeoTagger Pro which has its own battery, also. If it depletes its internal battery, it automatically switches to the camera battery. I easily get a weekend of solid use on a charge of the Solmeta battery, and I do not turn it off (nor do I turn off the camera, all day). The GeoTagger Pro locks in within 30 seconds when first turned on. I can even transport it 800 miles and it will sync up within a minute from its last fix. The accessory is by far the best accessory I've ever purchased. I've owned many GPS receivers and this one is amazing. Not the N2 or N3, but maybe this will help. OH, and importantly, the GeoTagger Pro gives you heading also. Quite useful.
