Orienteering Compass Comparison
The lineup: Silva 5 Jet, Moscompass 3, Suunto Arrow 20, and Prototype 1. While at it we included a brief look at the entry level Brunton 7 (Silva Type 7, Polaris)
Suunto Arrow 20All top end compasses were excellent for overall stability. Surprisingly, the prototype was judged better, if only very slightly, than the Moscow followed by the Suunto and Silva about equal. The prototype seemed to have a very slight delay in settling compared to the others.
When repositioning, the all needles would swing past the correct resting point a similar distance before settling. The prototype seemed to pause slightly at the extreme of the swing which might give a false reading if looking away too quickly. The others were smoother in the settling process though not much, if at all, faster. Interestingly, an east-west arm swing produced much more needle deflection than north-south.
For good measure we included the basic “field compass” Brunton Type 7 (Silva Polaris) and the Suunto Arrow 5 thumb in the comparisons. The Brunton compared surprisingly well for a lower end compass despite the much longer settling time. The two Suuntos seemed identical in performance though with slightly different capsules.
Comments by James: The Jet and Arrow had a “lighter feel.” The prototype had a “heavier feel.” The Arrow had a faint jitter.
Comments by Joe: For me and, I think, most orienteers, there was little to choose between the four in terms of needle performance. All had a similar very minimal wobble as I ran. The minor delay in prototype settling was usually not noticeable.
Factors other than needle performance could easily determine individual preference. Differences were greater in terms of features like ergonomics, ease of turning (especially with use), interchangeable capsule, sturdiness, propensity to develop bubbles, right hand models for the thumb versions, built-in magnifier, scale position, bezel style, area of map visibility through the capsule, etc. and, of course, price.

The Flip produced about 51 minutes of video. The first 20 minutes or so are shown in these two You Tube clips, unfortunately with much diminished quality.

A properly balanced needle will be in line with the baseplate even when tilted and should exhibit no delay or inconsitency in settling.
