I have about an inch of air in my compass yet I dont see any leakage.... but my question is, can it be refilled?.... i have the instruction manual but it doesnt cover how to, or if it can be refilled.... thanks.
this one is in perfect shape, it has always been covered and looks like new, and yes, it works great but the upper light doesnt work too well cuz the liquid is too low to catch it and carry it so it looks kinda strange at night. the lower light works ok but it would show the card better if both were illuminating the card properly.... but its all goodYes, most compasses can be refilled. A very pure mineral oil is used. I would research what brand to use from Ritchie, if Plastimo is no longer in business. You would have to carefully remove the compass from the bulkhead mount, & look for a fill hole. If it has a plastic frame, the the manufacture may have welded the plastic opening shut permanently. If it has to be drilled then I wouldn't risk damaging the globe. Many compasses have a bubble inside the glass globe. It won't hurt the performance or accuracy, its just an aesthetic defect. Your lucky if you globe isn't crazed or fogged up. I think the Ritchie models are the most durable. You could always look for a used one in good shape oline-Ebay, etc.
