Tritium Compass

Our range of Compasses utilise the Plastimo IRIS 50 hand-bearing compass and they are self-illuminating via the use of extremely reliable H3 Trigalight sources without the need for batteries, bulbs or switches. The Trigalight sources consist of four gaseous tritium light sources which provide a completely independent means of light generation. No batteries or charging with ambient light are required. There are no associated moving parts and because the unit is continuously energised, there is no need for a switch.
