GPS for Nikon D800

I have used a Solmeta N2 and a Aokatec AK-4N bluetooth adapter. The Solmeta doesn't work very well because a bad connection in the interchangable data cable. The Aokatec has never let me down. I use a Holux for pairing with the bluetooth adapter.

Both of these, and a Garmin has been used north of 80 degree without any issue.

Do you have a smart phone? You can try this: http://www.youtube.com/watch?v=Dp1KCkItmf4&feature=plcp

EDIT: ups. Just noticed the Alaska bit. Your phone might not do that well... But anything that can export GPS data should work fine.

BlueSLR looks very nice.

It works for me, and not expensive!

None of the web links to blueslr seem to be working. Anybody know if the company is still trading?
App is still on the app store, but that doesn't mean too much.

I researched this issue for my D800E. A recommendation that I saw posted several times on various sites was the combination of the Holux GPS locator and the Aokatec 4NIII receiver that fits on the Nikon 10 pin connector by the lens. I used this on a recent trip to Italy and I have serious criticisms of this combination. The unit was very inconsistent in connecting to a satellite, even within the same general area. Sometimes it would connect fairly quickly (1 minute or so). At times it wouldn't connect at all and often I would turn it on, get no connection and then find that it had connected well into the shoot.

The second major issue is that battery life is limited. Four days into the shoot, the low battery warning turned on. The lithium ion battery that is included (Model: HX-N3650A) is  not rechargeable and expensive. (on the website batteryupgrade.com it lists for ~$28). I also had no luck finding a rechargeable battery. So consider just how expensive it is to use this unit. Ridiculous!

So that's the bad news. The good news is that I think I've found an excellent solution in the Solmeta Geotagger N3. The unit works off the Nikon battery and supposedly (based on web research) is not a significant additional drain. It's powered through the 10 pin connector by the lens, so there's no cable interferance that occurs with units that plug into the connectors on the side of the camera body and preclude rapid tripod switches from landscape to portrait orientation. The receiver/transmitter unit can be fitted onto the hot shoe or on the camera strap, etc. It's feather weight. It consistently and quickly picks up a satellite signal. It also has an "indoor" feature, which means that if you're shooting outside and then go inside, it will retain the prior geotag info.

I think this may be a very good solution and I hope these comments are helpful.

Two years ago I used a Micnova on a Nikon D90 on an Inside Passage cruise. The GPS coverage was spotty. In April of this year, we took a round trip Hawaiian cruise from Los Angeles. Again, the percentage of tagged photographs was low. I don't know if it was because of the GPS unit or the area. However, in crossing 5,000 miles of ocean, you would think it would be better. My future Son-in-law has a Canon GPS on his Canon camera. My daughter took a trip from LA to Klamath Falls, OR by train, to Portland by car and plane to Glacier NP last month. Every single one of his 1000 plus photos were successfully tagged.

I just bought a D800. I need a GPS that is as reliable as the Canon. So far, I have not read any reviews for GPS units for Nikon with any where near that level of reliability.
