I am not sure whether you mean the rotating bezel Steve. Actually, I am not sure what you mean not having seen the type of compass you are referring to. Declination is a necessary calculation (adjustment) when you are transferring data to and from the chart. If you are plotting your course and writing down bearings on the chart, you will (of course) compensate for declination so that the reading on your deck compass reads true without the need to perform the mental calculations. The rotating bezel is necessary (or may I change the absolute to 'most accommodating to have any sort of accuracy in') to transfer bearing readings onto the chart unless you are using a 'Nav Aid', parallel rules, or a device I made with a grid and a compass rose on transparency paper with declination compensated for. The true north part of the compass rose is pretty much neglected by my methods. In fact, true north has little relevance unless you have your gps preferences set to it. I wouldn't consider a hand held without a rotating bezel. > > Steve Scherrer wrote: > > > > I would skip the part about looking for a compass with adjustable > > declination/ variation.
