    Re: Sisteco Primatic Handheld Compass

    On Wednesday, March 17, 2004 12:03 AM, Robert Eno asked about refurbishing
    or replacing his Sisteco hand-bearing compass.
    
    You may have a hard time replacing the tritium/phosphor illumination
    capsule. Current hand-bearing compasses use light-activated phosphor
    illumination (the kind you have to "charge" under a bright light) or
    battery-powered lights. Safety concerns appear to have won out. Tritium is
    pretty benign, being a low-energy beta emitter, but if you managed to break
    the capsule and swallow the stuff... well, I leave that to your lawyer's
    imagination.
    
    I can highly recommend the hockey-puck style compasses like the Mini 2000.
    They are easy to use day or night, smooth sea or rough.
