Service:
The device can be easily operated even when wearing gloves and with the buttons and the joystick. Although the joystick seems a bit fragile, but has so far proved to be very robust. The device has a pleasant weight, although the arm is difficult when you hold it for hours in front of him, but that's probably inevitable.
Card function:
The Topo-light card for geocaching perfectly adequate. However, I have also a variant of the OpenStreetMap plan (map of Kleineisel to 4GB Sandisk SDHC). This can also work wonderfully. However, it takes a moment for a card section of the nearly 2 GB file is read. However, this is good to handle.
Geocaching:
The information from the GPX data is well read. However, the function I quickly lacks only the description without reading the cache to enable the same. This is sometimes a bit time consuming.
Note for beginners: "Paperless Caching" is a rather somewhat misleading term. For notes with multinationals or Mysteries nevertheless you need a notebook or similar, however, saves you print out the instructions.
Satellite reception:
With the latest firmware I had been outdoors always good reception with an accuracy (according to equipment) 3-8 meters.
Compass:
Most of the compass is a useful addition, but you can not always rely 100% on him, because sometimes does not match the orientation shown the actual.
Conclusion: Go geocaching a great device with great strengths and little weaknesses.
Practical accessories: The carabiner can attach the part go to the belt loop or bag or backpack. This is very pleasant, because the part of the time but is heavy in the hand.
