I just got Nikon's GPS unit for my D3/D3x. I was shooting in Zion NP and wanted to use the GPS and Cable Release at the same time - can't as far as I've researched - same 10-pin connector. Am I missing something? Would a Y cord allow similtanious use? Who makes one?
I don't think it's a hassle. It has a clip attachment for your camera strap so you don't have to use the hotshoe.
Seem very accurate. It does drain the battery more quickly and takes about 10-30 seconds to capture a satallite depending where your located. Example - takes longest to aquire inside my home.
