The GPS receiver is supposed to plug directly into the Nikon camera? Which model fits better? A direct comparison of the Dawntech ECO Pro-F with the AK-G1s from Aokatec.
For photographers who want to attach the GPS receiver directly to the Nikon DSLR camera, there are currently two models. By comparison, the AK-G1s from Aokatec, the two ECO Pro-Fs from Dawntech. All are designed for the professional line of Nikon SLR cameras.
Revised di-gps ECO ProF-M
[Update October 2013] The improved Dawntech ECO has been added to the comparison.
What are the strengths and weaknesses of the Geotagger and which is the better choice?

Strengths and weaknesses of GPS receivers
The Aokatec clearly has the better case. It is more compact and is closer to the camera. In addition, it is secured against falling out with a metal screw. The Dawntech of the first generation turns out too easy and stands out, which can lead to damage. In the second version the knurled screw was added. The Dawntech V1 is missing a switch to permanently power the GPS receiver. So frequent, long-lasting restarts of the GPS receiver are necessary. After the update, the software was improved so that a switch is no longer missing.
A remote release fits all geotaggers. Advantage of the Dawntech models: The well-known 10-pin accessory socket can still be used. The AK-G1s requires a remote release with a 2.5 mm jack plug.
The GPS reception quality of the Dawntech is clearly ahead. A GPS fix is made quickly and the positional accuracy is top.
The best way to look at the details of both geo-excavators is in the extensive field tests: Aoka AK-G1s , di-GPS ECO Pro-F and the new ECO ProF-M .
In terms of price, the Aokatec is in the lead. For more than twice as expensive Dawntech offers a German dealer with warranty and good support.
Which Geotagger to buy?
Aokatec or Dawntech – everyone has their advantages
Each of the loggers has its advantages and disadvantages. Therefore, I do in this case with a clear recommendation very difficult.
The best would be a combination of both. Housing from Aokatec and electronics from Dawntech.
[Update October 2013]
After the Dawntech update my recommendation goes to the new ECO ProF-M . Only the further protruding housing remains as a small point of criticism.
