That is a very nice demonstration. Of course there are many many ways that you can approach this, and the choice that you made you demonstrated very well.

Thank you!

Thanks for sharing! Best instructions I have seen on 2 person pull system, especially on working around the braking knots. Clear and easy to follow! Braking the initial fall seems like the crux of a situation though. Bet in needs a good amount of practice!

Thank you for your comment. It is indeed the hard part arresting the fall. We do not recommend it but the technical system could be useful anyways. For example if number 2 out of 3 falls in, you probably wont have enough extra rope to do any other system. Glad you found it helpful. Nicco Founder Nunatak adventures.

Thanks for this detailed video. I'll be doing a 12.5km traverse over a glacier in Alaska with one team member this late July, and this was good learning material in addition to an in person crevasse rescue course.

Thank you! Appreciate your comment.

Hi, thank you for excelent video! Please what thicknesses of reep cords do you use? I am wondered if you have 9mm rope if you can use 6mm reep cords for all used purposes.

Hi thank you for your comment. Yes you can but if you look for all purposes best 7mm cause you can use it to make anchors as well on ice climbing trips for example. But if you would own a glacier travel rope of 8mm you would need the 6mm cord to have good grip doing prusik hitches.

@@nunatakadventures66 OK, thank you so much! Take care :)

Good video, thanks for sharing! I have a question - is the assumption here that the tension on the rope will be too high to be able to undo the butterfly knots as they approach the traction device? Is it strictly speaking necessary to use the cordelette? Or does it just make it easier.

Hi Andrew and thanks for your message. Indeed the tesion is too much to physically be able to undo the knot. So the method using the cordalette is necessary to put the tension beyond the butterly knot into the prusik to then undo the butterfly so the rope can be taken into the ratchet (micro traction). Not the only method but an easy one to practice. Hope this clarify :)

Hello! And thanks for the video. What length of rope were you using for this demonstration?

Hi, thank you for your comment. In this case the rope is 40m, 9mm. The quickest rescue would be doing a “drop loop 2:1” (kzread.info/dash/bejne/q4h82MqCgNauqMo.htmlsi=X3avewYb3f5Hs373) but if the rope is not long enough, you have to do direct pull or 3:1 which is covered in the video you just commented
