Ritchie GM-5-C 5" GlobeMaster Binnacle Mount Compass Cover - White

The Ritchie GM-5-C 5" GlobeMaster Binnacle Mount Compass Cover in white is an essential protective accessory for fixed marine and navigation compasses that demand reliable, all-weather operation. Designed specifically for Ritchie's Globemaster binnacle models, this cover shields your compass from salt spray, UV degradation, moisture infiltration, and environmental contaminants that compromise accuracy and longevity. Whether you operate a vessel, rely on navigation equipment for backcountry expeditions, or maintain critical orientation tools in a preparedness kit, a quality compass cover is non-negotiable for preserving instrument calibration and optical clarity.

This cover fits Ritchie compass models SP-5B, SP-5C, D-515, and D-515-EP, providing a snug 5-inch protective envelope that safeguards the dome and card face without interfering with mounting hardware. The white finish reflects solar heat, reducing internal temperature buildup that can affect magnetic needle sensitivity and dampen card movement. Constructed to withstand marine environments, the cover remains in place during rough seas and extended storage, preventing dust accumulation while allowing quick removal for navigation checks. Its compact dimensions (5 x 2 x 10 inches) and minimal weight (0.3 lbs) add negligible burden to any vessel, pack, or fixed installation.

Wilderness instructors, maritime professionals, and emergency preparedness planners recognize that compass protection directly extends instrument service life and maintains declination accuracy for years of reliable use. This cover is ideal for vessels sitting idle between seasons, navigation systems deployed in harsh climates, and backup compasses stored in survival kits or emergency caches. Installation is straightforward—simply slide the cover over your mounted Globemaster compass, and it seats securely without tools or modification. For anyone investing in precision navigation equipment, this protective cover represents a small but critical safeguard against the cumulative wear of salt, sun, and moisture.
