Hone your slope angle intuition with the Backcountry Access Slope Meter. This lightweight inclinometer is designed for field use by skiers, snowboarders and backcountry users looking to estimate slope angles for aide in avalanche hazard studies. Hold the slope meter on the snow surface and a steel ball inside the liquid-filled gauge reads the slope angle. It's that simple. You can attach it to a ski or pole, and the flat edge conveniently doubles as a ski scraper.
