Backcountry Access Slope Meter
Here's what other sites are saying:
Consider the Backcountry Access slope meter an essential on ski trips. Knowing the angle of the slope you're on can help keep you out of avalanche terrain.
Backcountry Access is taking their education program into the snow pit. Their line of snow study products was developed in cooperation with North American avalanche professionals.
Before you pick out a line, you could do the old "Ehhhh, I think it's probably roughly maybe about a 40-degree slope, I guess", or you could whip out the Backcountry Access Slope Meter and actually get a real reading of the angle of the slope you're checking out. BCA hooked this inclinometer up with red, orange, and yellow markings to easily point out the most dangerous slope angles, and included a compass so you can double-check your aspect at the same time.
A steel ball inside a liquid-filled tube displays the slope angle on the BCA slope meter. Slope angle is a very important consideration in slope stability and this trusty device is a valuable addition to your backcountry kit. 0 through 60 measurable degree angles with marks at every degree Yellow, orange and red zones are marked for critical slope angles Attaches to skis or poles Stabilizes quickly for fast reading Doubles as a ski scraper
