Description
Silva Field MS is the compass we point people to when they are learning to navigate properly. It is a clear, simple baseplate compass with a rotating capsule, map scales printed on the plate and a rubber grip on the bezel, and it does exactly what a first compass should: take a bearing off a map and walk it on the ground. Silva build it for schools, youth groups and leisure walkers, and the Duke of Edinburgh's Award recommends Silva compasses.
Who it's for
Bushwalkers moving off signposted tracks for the first time, scouts and school groups, rogainers and orienteers starting out, and anyone who wants a reliable backup to a phone or GPS in the pack. It is the compass for a navigation course, a first overnight walk in the Blue Mountains or a day picking a route across open country in the Victorian high country.
Accuracy and features
- Rotating capsule: turns to set a bearing, built around the SILVA 1-2-3 System.
- Declination scale inside the capsule: for converting between grid and magnetic bearings using the note on your map.
- Map scales: a millimetre ruler plus 1:25,000 and 1:50,000 scales, the scales most Australian topographic maps use.
- Rubber grip: on the bezel, so it turns easily with cold or wet fingers.
- Detachable lanyard: hang it round your neck on the move and unclip it to work on the map.
Using it in the field
The SILVA 1-2-3 System keeps it simple. One: lay the edge of the baseplate along your route on the map, with the direction-of-travel arrow pointing where you want to go. Two: turn the capsule until its orienting lines run parallel to the map's north-south grid lines, north to north. Three: hold the compass flat in front of you and turn your body until the red end of the needle sits inside the orienting arrow, then walk where the direction-of-travel arrow points.
The clear baseplate lets you see the map underneath while you work, and the scales let you measure the distance to the next creek crossing or saddle before you set off.
Looking after it
Keep the Field MS away from magnets, phones and steel when taking a bearing, as they pull the needle. Store it flat in a pocket of the pack rather than loose with keys or tools, and rinse off mud or salt with fresh water.
