Tritium Coated Compass

[Mako]

Is anyone familiar with any sources of a tritium coated (self illuminating) compass that can be used as the primary on a boat? 3 or 4 inch card. This would be similar to the mil-spec handheld units. Therefore no electricity would be needed for nighttime use.

No but there are lots of small led penlights that can be had in red and the batteries will go a long way.
