I have the model just below the one you are showing in the photo. The model in the photo is the Pro Model, I have just the regular version which I purchased prior to the release of your model. It is a nice compass, but it is a bit heavy. I have switched from this and my Silva Ranger to a Suunto MC-2 Global Compass which weighs only 2.6oz and has a Global Needle. All 3 (or 4) are very good for usage for map and field and taking inclination readings (dips- as for Geology) or slope, or grade.
All 3 units are somewhat multipurpose usage because they will also serve as a mirror for many purposes including signaling.
Some may argue these mirrored compasses are too large and heavy, but I prefer something just in case for map and field compass readings. These compasses tend to be more accurate than most due to the sighting mirror and you also can set the declination.
