Product Description

SILVA TYPE 85 fits in smaller, less speedy motorboats, sailing boats, rowing boats, kayaks, canoes and surfboards. Permits 25 degrees heeling.

SILVA TYPE 85 should be positioned on a horizontally level and positioned where it can be easily read from all angles. Position the compass as far as possible away from iron objects or other disturbing magnetic sources as loud speakers, windscreen wipers, instruments etc. NB! SILVAs electronic instruments do not disturb the compass. When checking for magnetic disturbance, use an ordinary SILVA handheld compass, held in the fore-and-aft direction around the intended mounting site. In most cases 0.5 to 1 metre between the compass and the source of disturbance will be sufficient. Do not forget to switch on all electrical equipment near the compass when making this check. The packaging includes:
  • Compass unit
  • Mounting kit
  • Choice of sighting ring - both black or white included in the package
The compass should be mounted exactly in the boat’s fore-and-aft direction with the main lubber line pointing to the stem. The compass should be mounted on a firm base  to prevent oscillation of the card. To avoid engine vibrations on motor boats, a rubber sheet can be placed beneath the compass.
  1. Lever off the graduation ring.
  2. Remove the screws and mark the screw hole positions.
  3. Drill a hole with a 2.7 diameter drill.
  4. Attach the compass with the four brass screws enclosed. (It any other screws are used, ensure that they are made of non-magnetic material.)
  5. Push the graduation ring back.
Note the dimensions of the base - this compass will not fit in the circular recess of some kayaks (does not fit in Mirage sea kayak recess). For smaller recesses we recommend the Ritchie Kayak Compass.
