The tip on measuring the angle in particular is great! I've used mine quite a few times with no tuition, just cut slots then bashed it down and buried it. Fortunately I'm an engineer & had some idea of a sensible angle. Last time on the Ben I had difficulty extracting it & it would have held an elephant as the snowpack a foot down was solid.

Thanks for the video. What's the physics behind this angle of 40° ? And how much changing the angle (to 45° for exemple) is significant ?

Technology is amazing!
