Cambium Savers

[kram]

Looking to get one, unsure what length or whether to have an adjustable prussik type, or just plain ring on each end.

 

I'd be fitting it as a retriveable anchor when I get to the top. I dont generally bother with a throw bag.

 

I remember being told that they work great over limbs but difficult to retrive if around a stem. I imagine I would use it mostly around the stem at the top.

 

I currently use a small sling and steel carabiner for the purpose but its not retrievable.

If you have an 11m rope or one with low profile eye as in cousin, courant and teufelberger lines then the fimblclimb is very good.

You can't go far wrong with one of these.

The multiSAVER from TEUFELBERGER is an often proven cambium saver of polyester, which impresses with its well-thought-out...

It does appear to do everything except for being quite large and bulky to carry up on harness, and expensive for what is a peice of rope and three rings.

 

I have large and small steel rings and some spare rope already. I am thinking a tied clove hitch on the big ring in the middle will allow adjustment,  spliced eyes with small ring on each end. Or one end with a barrel stopper, I'm not sure if its useful to have one on each end.

 

A quick example without splicing, probably wants to be a lot shorter. Ignore the tail.

Theres a lot of knots in that setup, you're going to be getting that stuck A LOT.

Let's play devil's avocado here, decide we aren't buying anything, and instead streamline this device. What can we do?

[kram]

Ah, I made a mistake there, the clove hitch and stopper should be on the small ring with the large ring having a spliced eye, so that nothing can get stuck.

 

However after a quick test, a clove hitch wont work on a small ring as it wants to fold over, to become just two loops in the ring, although the stopper does stop it pulling out completely, its not going to be reliable.

 

Perhaps with a pair of bigger rings it could work, but I dont have them.

 

I was intending to avoid using a prussik loop but that might be the best solution.

Where did you get those rings from? Are you based in the UK? I've only found them on a Japanese website

 

If cost is an issue you can get a (non-adjustable) Stein cambium saver for £37 from Gustarts

Rings from here, tho steel may be over the top. I got them for use as cinching anchors where I didnt want to trust alu but the small is a bit small, and big is too big for that use, so instead have some DMM 34mm alu ones for cinching.

Yes seen the Stein ones, I think their shorter 90cm one will be about double the length I want. The longer it is, the lower your top anchor becomes on a small stem. I assume that any multiple wraps around the stem makes it non retrievable.

The multisaver is a brilliant bit of kit, on small trees you set it long when dropping away from the anchor so your rope isn't rubbing on the stem and shorten it up when you go back up.

 Chogging a pole you lengthen it as the pole gets fatter, or round lumps, then you have a descendable drt anchor all the way down which is safer than just throwing climb line round. Put the rope through the third ring first, stops it hanging down and getting spiked.

 

So a well thought through, reliable, safe bit of kit. Works well, retrieves well, passes loler. Much better value in my opinion than eg ART ropeguide at over £200.

 

I haven't used my fixed length cambium saver once since buying it, definitely wouldn't waste money on one. Once you get used to a multisaver you can't go back, the fixed one is always too long or too short and hence a pain in the arse. As you say, wrapping ends your chance of retrieval, forget it.

 

I wouldn't hesitate to buy another.

 

Edit: forgot to say Stein make a version now as well.
