Anyone know where to get a face pin spanner for use in removing/replacing dive computer batteries, such as on Suunto Zoop, Cobra, Vyper ? I have a face pin spanner I bought years ago with larger dia pins on one side for reg covers, etc. and smaller dia pins on the opposite side that work perfect for dive computers. Internet searches not very helpful. Northeast Scuba Supply seems to have one with the smaller dia (.78mm) pins only. Anyone use these?
