no use without an internet connection, unreliable software

Before deciding on this equipment should be aware of the operation and the associated advantages and disadvantages clear.
The Geotagger itself only records raw GPS data, the actual positioning is then subsequently on PC instead.
As with the exact satellite positions at the time of recording required, the included software loads that data to a web service that constantly updates these data and holds at a certain date in the past. The service is apparently operated by the manufacturer of the receiver chip used.

Advantage: High Speed ​​recording and low power consumption
Disadvantages: bringing together the position data with the photos requires an Internet connection and you are the operator and of the accompanying software dependent

You can download the raw data with the software and the Tagger and cache on the hard drive and thus the Geotagger open spaces again for further recordings. I have not tried it, but think it is a very important function, because you just rarely has an internet connection when traveling abroad and would otherwise be limited to the 2,000 images that can be stored on the device.

To the device itself:
good battery life, usually sufficient accuracy, but in difficult conditions can often no useful position data be recovered (so I could but live). Another problem is as already often mentioned here that the hot shoe adapter very easily detached from the device - can here and should make do with a small piece of tape - my Tagger would ever landed almost in the water. On camera hotshoe itself the tagger is positioned securely.

Software:
Here catch my opinion to the problems. The software is limited to the essentials, which I do not always find a negative, but a few more features and configuration options were already desirable. In the first test, the position data is always assigned to the correct photo and everything looked initially like it would work as well.

Unfortunately, I realized from the first trip with the Tagger that the software with the assignment has a huge problem to return. Many photos, which certainly not Geotagger was placed (in part also interior shots with ext. Flash) were assigned (already contained in the series of recordings, but in some cases only three days later than the picture recorded) without any recognizable system any position data. Even with the photos where there are certainly correct position data, I have found some mismatches - have been partially assigned simply another position data. One can not rely on an accurate allocation so unfortunately. Very disappointing.

Since the software also is unable to export the location data, for example, allows the GPX or KML format, and thus can be used for assigning no alternative software, the device for me is not useful. Incidentally, I have tried in my experiments, the current version of the software, which is offered on the Manfrotto website for download. Hopefully that is reworked here because the device itself is not bad!
