The Explorer is a compact Ritchie compass with a 2-3/4 inch direct-read dial. It has green NiteVu lighting and built-in compensators for adjusting out deviation, plus a sun shield that moves. It is made for marine and automotive use and is described as easy to install on a windshield or dash. The movement pairs a sapphire jewel with a hardened steel pivot, and the compass can be repaired and carries a 5-year warranty.
Our take
The built-in compensators are the useful part here: you can trim out deviation yourself once the compass is mounted. The dial is 2-3/4 inches with green NiteVu lighting, and the repairable build and 5-year warranty mean it can be serviced rather than replaced.
From our buying guide
Ritchie says a magnetic compass needs no electrical power to work, and that a GPS gives course over ground, not heading. Magnets, ferrous metals and current-carrying devices near it can cause deviation, so the spot matters too.
Check before you buy:
- It's balanced for where you boat. Ritchie advises buying the zone central to where you boat.
- The dial suits your helm. A flat card is read from above, and a direct-read dial from directly in front.
- You can compensate it, since not every compass has built-in compensators.
