Nikon GP-1 GPS Unit for Nikon Digital SLR Cameras

User Reviews about Nikon GP-1 GPS Unit for Nikon Digital SLR Cameras

Unit works very well and the information is placed in the photo meta data without any issues. Using a cable release requires a cable with a different adapter. -- Nikon GPS GP-1

First and foremost- many people have talked about the battery life of your camera being affected- I can't tell a difference. I took about 1800 shots on my D-90 before the battery was down to 24% (battery is about 6 months old). The GPS is very accurate, when it gets a signal. In my experience, if you have a clear view of the Southern sky, it will lock in about 45 seconds if you have traveled a great distance since its last power-up, otherwise, 5-10. If you don't have that clear view, however, it could take hours, or never lock at all. I took this unit to the bottom of the Grand Canyon last week, and got no signal the entire way (as I went down the south rim). However, once I was at the bottom, it locked within a few minutes. Once it locked at the base of the Canyon, it had a strong signal on the way back up. Many people have accurately commented that the cable is cumbersome and needs an L-shaped plug, because it is in the way. However, within a few hours of using this, I adjusted my hand position such that it did not matter. The summary:

Myths:
It will drain your battery- Nope! Not noticeably!
It blocks the flash - Yes and no- you have to use the strap hook, but, if you're using a GPS, presumably you are shooting outdoors....
It takes so long to get a signal, you miss the shot- FALSE! your camera will still take that fast shot, even if the GPS isn't locked. Just don't make the mistake of missing a photo-op because the GPS hasn't locked on yet. If you have 5-10 seconds, it shouldn't be a problem

Basically, it does what it needs to do. It is the first generation in a long line of what is sure to become an integrated feature in the future. Have fun with it! -- Good product, but needs improvement

Purchased the GP-1 to help organize photos with the "Places" feature in iPhoto. I've used the product for three weeks and used it on a cruise ship and while touring Bermuda, both on land and ferries. I am very pleased with it.
I would have given the unit 5 stars but the interface on the D90 is a problem. Although I list more Cons than Pros, the GPS works great and gets the job done.
Pros: The GPS may take from 5 to 90 seconds to determine its current location, it depends on its last known position and any obstacles. Once established, it maintains commo even when shadowed by buildings, trees, inside a bus, etc. If the camera is turned off and the position hasn't changed considerably, the GPS reestablishes position usually within 5 seconds of powering on.
Cons: Specific to the D90 interface.
First and foremost, the interface cable is awkward and without certain precautions will lead to damaging the D90 input connector. The cable connector comes straight out of the camera connection located on the bottom left side of the D90. When cradling the camera from the left side, for stability, the user needs to be cautious not to apply any pressure to the cable/connector. Over the long term, damage to the camera's connector could result in a costly repair. This needs to be addressed by Nikon, but until then, the owner is on the hook for any damage and repair costs.
Second, the hot shoe mount isn't very practical. When you look through the view finder with the GP-1 mounted in this position you might bump the unit with your forehead. In addition, the GP-1 interferes with the pop-up flash unit! Also, the cable dangles and is in the way of your fingers. I used the supplied adapter to mount the GP-1 to the strap and had the excess cable held in position with a small velcro strap. This worked very well during my travels. As an added precaution against causing damage to the camera connector, I disconnected the camera connection whenever the camera wasn't in use.
Finally, battery life is shortened when using the GP-1. The unit uses the camera's battery for power. To ensure that the unit remains locked on to the satellite, especially when you're moving about or with potential obstructions (between tall buildings, inside a moving bus, on stateroom balcony, etc.), the camera should be left powered on. Not a big problem, just keep a fully charged battery handy if you're going to be out for the entire day. -- Geo tagging works great with Nikon D90

This product has been on my wish list for some time however after reviewing the Eye-Fi wireless memory card that offers geotagging I have reconsidered my purchase. I have not been able to use the Eye-Fi wireless memory card myself but when I saw that it offered geotagging it gave me an additional option to consider. Especially after I realized this device takes up the space of my shoe preventing me from having my flash attached to my camera at the same time. -- Review the Eye-Fi Memory card before buying this product.

This is really cool, provided you actually read the directions. For this to work reliably, you need to change a default setting on your camera. If you do not read the manual, you would not know this and therefore be disappointed.

I am impressed how quickly, even when the signal is attenuated by trees or inside a building, it access satellites ad determines position. This is really great!!!

You must make sure that you go to the Setup Menu | GPS |Auto Meter = Off. If you do not do this you will experience the same problems that other reviewers who, foolishly, have not actually read the manual and therefore have experienced the foreseeable problems. -- Despite what other say...
