The PoleClinometer slope meter is color coded to help you quickly identify slope angles that are more prone to avalanche. The color coding is described on the use page in detail.
Wind is not your friend in this case. You won’t get a good reading from your PoleClinometer slope meter if the wind is blowing your pole around. If you take a lot of slope readings from windy ridgetops, you’ll probably want a second form of inclinometer with you (see above). But PoleClinometer will still be very handy for quick “on the go” slope angle readings when you’re not exposed to high winds.
If you want to measure slope angles in all conditions and scenarios, I’d recommend a 2nd device to supplement your PoleClinometer slope meter. My favorite is the Avalanche Inclinometer app: Best avvy inclinometer app hands-down, and works in all use-modes (sighting cross-slope, sighting up/down-slope, & contact measurement) unlike most other apps & devices which usually only support one or two of these use modes.
The real beauty of the PoleClinometer slope meter is it’s so quick and easy. No stopping to dig through pockets for your device. Your pole is always in your hand. Just dangle it, and sight your slope angle! You can literally take measurements in the skintrack at a moment’s notice without even breaking stride. Most users find they take slope angle readings far more frequently with their PoleClinometer slope meter than they did with their prior inclinometer devices. Lots of quick measurements as you move through the mountains add up to a better overall picture of where the risky terrain might be.
If you take a little time with a measurement, you should be able to get a reading within about 2 degrees of actual slope angle. For super quick “on the fly” measurements, probably within 3 to 5 degrees is more realistic. Bottom line: It’s at least as accurate as the average pocket inclinometer or inclinometer-equipped compass.
You’ll find detailed instructions on the use page.
ABSOLUTELY NOT! Only YOU can do that, with a combination of good education, good local knowledge, and good decision making. Slope angle is only one piece of the puzzle. Take a sanctioned Level 1 avalanche course to get started, and approach the backcountry conservatively.
