    OP - this thread should be in the slide zone.

    Same here. The Dioptra app is pretty cool. Just downloaded it and played around with it around our shop area. Thanks isbd.

    I always tell folks to take their inclinometer out a measure a lot of slopes to develope their terrain angle eyeballs. It's a good preseason training thing. Measure your garage roof. Every time you pull your car out take a second a memorize that angle in your brain.

    Walking out on a slope convexities to measure looking down slope can be tricky and dangerous. Be VERY careful when you do this, since you'll likely be on the major stress point of the slope.

    Back to the original question, I'll check slope if it's an area that is steep enough to be concerned. With us, we're generally meadow-skipping on 25-30 slopes that we know well and, aside from some smaller terrain traps we are aware of and avoid, have never been a problem. As I tell my wife, we choose slopes that are historically documented as never having slid in the history of mankind. Obviously, not always the case and when we do venture into unfamiliar territory with steeper pitches, it's in low conditions and I do take a slope as much from curiosity as anything. Rarely are we in the 35-40 range.

I suppose this could bite you if you were holding your phone and beacon in the same hand during a search but my arm is longer than 50cm and my phone stays in airplane mode in my pocket. I have practiced and do practice searching using my beacon with my phone off, fully on, and on but airplane mode; I have not seen a discernible difference in search effectiveness. So on the one hand, I've read some things about some devices interfering with some beacons in some circumstances; on the other hand, I have plenty of actual experience effectively performing beacon searches with my real every day bc kit, which includes my phone. Anecdotally, of all the people I've ever toured with, not one powers off their phone completely or has ever asked me to do so (or even mentioned doing so). So I don't worry too much about it, and phone app clinometers are nice.
    Yup. Definitely do your beacon check with how your phone will be running on your tour. I do airplane mode and if there are any search issues, it's powered off. A buddy's phone halves his search distance when it's powered up, sending/receiving (non airplane mode).

    I run both Dioptra and Clinometer. It's good to train your eyes from both perspectives.

    Could somebody please do a refresher post on current info related to phones and transceiver interference, preferably in a standalone thread? I have some ignorant confusion. I believe tremper spoke about it and addresses in his new book. I used to do airplane mode. Lately, I’ve kept it off. I like using it for quick pictures.

    I have a suunto compass with a slope meter that I carry in a pants pocket. I pull it out frequently. It has helped me and has been a clear component of me backing off an objective.

    Don't, but probably should to at least train the eyes to be better at guessing slope.

    What i do pay very much attention to, is run outs and traps.

    My kid gave me one of them angle/thermometers that straps to your pole so did a tour on boxing day hit the button and its dead

    it wasn't really dead they just don't work when its colder than -20C

    i gotta dig that thing out and try it again

    She said it at a "survivors/PTSD" clinic this past summer.

    Drift: Are those clinics common?

    A friend of a friend was a survivor (and first responder) of the Durrand glacier incident. Seems this person had been (and still may) want to participate in such a clinic.

    I measure slope angles habitually. It’s a fun and easy game to play to see how well my eyes gauge reality. Any and all tools that get backcountry skiers to slow down and pay attention to the snowpack, weather and terrain help create a safer experience for all.

    It matters.

    No, their not comman. This was a panel discussion at an event not for survivors, but for patrollers/s&r/CAIC types.

    Slope Angles — Do you measure 'em? How important are they?

    Thanks for the additional info.

    Looks like dioptra is android only. Are you iPhone users using clinometer or something else?

    ^ our local avy center has one built into the "take a picture" function in that app, but otherwise I use Steve's Badass Avalanche Inclinometer, I think in the app store as just AvyInclinometer or something

    Theodolite for sighting up/down slopes. Steve's badass clinometer or whatever it's called is for on slope measurement (it stores gps coordinates of each measurement). Or pole stickers. Or compass with clinometer.
