Thx for the tutorial, really helped! Keep doing a great job! :)

[@REECOIL_DOT_COM]

Thanks for the great feedback! 😊

[@markelmes4645]

Great tutorial. 🤙

[@REECOIL_DOT_COM]

Thanks Mark! What knee ascender setup are you using at the moment?

[@rossmckitrick7806]

Very clean 👌

[@jibiroo]

Nice rig thanx

[@georgelucas1693]

Where can we buy both fids that you used in this video?

[@user-us7pk2dy3k]

Muy buen video en horabuena, me gustaria preguntar se puede ascender con un ALPINE UP ? en lugar de lo que tu usas ?

[@ushi120]

5mm Robline Dinghy control line has only 4mm dyneema core.
If you don't need the cover, 4mm dyneema will be good enough!

[@REECOIL_DOT_COM]

That would definitely make it even more compact! I do like the cover on the dyneema though, just to avoid the dyneema strands picking.

[@mathiashaenel2832]

Im using 3mm dyneema without cover for 3 yeas now and its still fine.

[@habiullah8362]

Please give a clear video on how the legs are locked with the rope while climbing

[@gallant_hung]

Would you suggest a website that can buy all the items need for building the knee ascender kit?

[@REECOIL_DOT_COM]

That’s tricky. The ascender would come from an Arb, rope access or Rock climbing shop as well as the DMM xsre carabiners.
The elastic shock cord from a hardware store. And the dyneema cord from a sailing shop.

😍💪

[@user-jd8dx4ql1k]

What is the brand of the dyneema rope ?

[@REECOIL_DOT_COM]

It’s the Robline Dyneema Dinghy Control Line. The 5mm has a 12kN rating

[@robo11735]

Won't the cord come up a little short since you didn't do the Croll marking while it was girth hitched?

[@REECOIL_DOT_COM]

True. Probably lost about 5-10mm from the spliced large eye to girth hitching it. Good pickup 👏🤙

[@pfv3462]

Can I ask you an important question?
Is the TasLove 3 a safe device?
Thank you for explaining how to make this knee ascender

[@REECOIL_DOT_COM]

I do like the Tas Lov3. But only for very specific uses IMHO. I don’t think it’s a good device for moving around the canopy of a tree (it doesn’t have the fine adjustment of a hitch, zigzag, rope runner etc) it is great for ascent though and I do think it is a safe device when used correctly in the correct application.
I’d compare it more to a Petzl ID and Rig, ISC D4 and other rope access descenders but with the benefit of being able to ascend a straight rope. It doesn’t have an anti-panic function though, so that’s something to bear in mind.
