This lightweight (4.6 oz) compass is comfortable to hold and accurate – factory certified to within 1 degree. It features a liquid-dampened card with photo luminescent night lighting requiring no batteries. The contrasting black and red numbers on the compass card make it quick, clear and easy to read. Its sturdy rubber housing gives plenty of protection, and its integral lanyard serves as a convenient neck or wrist strap. It comes with a lifetime warranty, so this is most likely the only hand bearing compass you will ever need to buy. The package includes directions for use and a numbered calibration certificate.
