Rope length measurement device for belaying - do you like that?
|
Hi all, |
|
If a belayer doesn't notice the half-way point pass through the device...they probably should be belaying. That said, I'm curious how your proposed device would get the attention of a belayer. I'm picturing some sort of dog collar triggered by the passing of the mid-point through an ATC. I wouldn't use it. |
|
some middle ink marks are a bit stiffer and youll often notice the middle mark going through the device ... especially on a smart |
|
I'll re-post what I did on supertopo because I'm bored: |
|
Just add quarter way as well as half way marks to the rope. Job done. |

It would be an interesting device, but I doubt anyone would use it. It would have to be lightweight and unnoticeable for the most part. Definitely limited to beginners for the most part, but I can see some uses (rapping in the dark over an edge where one can't see the ends on a windy, chicken-head pocked route?). Seems too specific for me. |

If your climbing at a developed sport crag then a 60m will usually do. I pitch that needs a 70m would look unusually long I would think. Could be a nice idea I suppose. Novice climbers need to get in the habit of always knotting the ends of their ropes. This would mitigate A LOT of accidents. |
|
If there's ever the slightest bit of doubt, or sometimes just for shits and giggles I use this device. The best thing about it is that it comes with the rope for free. |
|
On second thought, I suppose a slip knot at the midpoint of the rope would be a pretty fool-proof method. Easy to "untie" while belaying. |
|
I think this is kool but better suited for rappelling. I have done cliff mapping studies where trying to figure out distances on a cliff was obnoxious. This device would account for rope stretch when the rope was weighted and would be ideal. But how are you going to make it work? with a rolling arm that rolls along the rope and keeps count? |
|
I don't think its a good idea because if you do get it people may stop tying knots in the end of their ropes because they think they would know how much rope is left which could lead to more accidents. If they don't stop tying the knot then your device is pretty irrelevant or just an expensive toy. |
|
By the logic above then we should all go back to hip belays and forget about gri gri's it's not a substitution just an added measure like a shunt over a Prussik for rappelling |
|
I want an electronic rope that you can look down at your knot and it tells you that you are at the end of your rope, maybe it'll beep once at 20 feet from end, or send a shock to your junk, or something similar??? |
|
I think this is a cool idea. It would definitely be useful on long multipitch trad routes ("How much rope is left?"..."Uh, a small pile!"). No one likes to hit the end of the rope and have to down-climb back to the last good belay stance, although it doesn't happen too often. |

It would, however, be a terrible idea for a non-bicolor rope. A mark that could be confused with the middle mark is quite dangerous, since while rapping (in the dark, while tired, etc.) it could be quite easy to accidently center the rope on the 15-meter mark instead of the middle mark. This has happened to people, they have rapped off the short end of the rope, and they have died. |
