Heres my setup- This is the microfrog designed by the late great Scotty Sharpe. keeps it all nice and compact. sorry bout the seperate photos

Heres the inline retrievable redi ive come up with that has no retrieval line, and doesnt use the tail of your rope to retrieve. Tom Oldmeadow kick started this idea but this is what ive finished up with. To retrieve i just tie a slip knot under the HC and clip into it. Attach a retrieval ball using elastic about a foot above spliced eye and pull the hitch side (the same as retracing your line through the tree) so the that the spliced eye side goes upwards. The ball then hits the clip and undoes the whole system. The cinch backs up the ropeman and the ropeman backs up the cinch so no stopper knot needed. If the system is unweighted the cinch stops at the ropeman. Works really well and its so nice not having to use your tail to retrieve-Big thanks to Joe Harris too for making the VTIO papers on redirects that started all this off. It looks gear intensive but is amazing quick to install and the benefits (for me) outweigh the hassle of carrying the gear.

might go and see the beal guys today then, cheers Max

yeah thats exactly what happens mate, a very easy step and works really well.

it all gets a bit tricky especially once you try and work it out including the smaller limbs your running over as well............

tree Frog/Rope walker is what i use.

bugger, but thanks anyway for having an ask.

the brace is well off bro-way too hot for it. i think some video was taken of the demo so ill try and track it down

a few pics from today showing off the new Stein range, GRCS, PRCB and cool little rigging tips. Im sur more pics will be at the treetools site soon as heard the Nikon clicking away all day! Reg-your gear is sweet. and well done to Rossi for showing it all so well.

hey bro, its cool to have the discussion! Weve done some dyno tests on anchors showing how much force is created by footlocking and it gets pretty high due to the nature of the technique and srt (Handled,cest,foot ascender) was way less movement. Hopefully we will get to do them again and this time video it all, getting hold of the portable dynometer is the hassle. I totally agree that more force is created by tieing off at the base of the tree and thgis is why i will always try and anchor to another tree to lower the angles-from memory i think 120 degrees lessens the load to 0x.(the angles chart is up somewhere to confirm.correct this) I also like having the rope running through lots of minor limbs as this also spreads the load over more branches. Obviously it wasnt the case this time as it snapped!! One thing is that it was a decent limb that i would of anchored to once i got to the top and would of 'probably' broke during the climb anyway, so my fault for choosing an unsuitable anchor but thats all easy in hindsight. I do think that SRT opens up a whole new kettle of 'potential' problems and hazards that have to be assessed before use and so correct training is vital. The other reason for choosing SRT ascent is that its bloody hot here at the moment and so the efficiiency of this technique whilst doing multiple trees per day makes up for the limitations it causes. Real good points you make though bro:001_smile:

its for a fall arrest type system.

any idea where i could get them from? CE makes no difference to me down here in NZ, cheers.

never. theyll be back, just stick with it bro:001_smile:

quality mark. I thought you had permed hair?

cheers kev-any idea on how dynamic the beal is? im after something that is as dynamic as possible without being a bungee

sorry for the confusion, yeah i meant kernmantle as core bearing the majority of load. Thats a really interesting test you got going there but would having both ends spliced mean that the ropes gets used alternate ends and so the bunching towards the splice gets stretched back out evry time its used? Having just one spliced eye means that all the bunching is always going to be going towards the eye? In the test, are the 5 descents done without milking the rope back away from the splice or just left as is and repeated? Are you doing the tests with a bowline on end to act as a constant to see what the bunching does to this? Nice idea for a test mate:001_smile:

Is there anyway to terminate dynamic rope apart from knots? can it be stitched? i see why a splice shouldnt be used and i presume its the same for stitching but if anyones got any other ideas then thatd be cool. cheers

How come? what causes this? on 16 strand, double braid, kernmantle? interested to know................

all done bro but cheers anyway

pies pies pies pies

Whilst this is quite neat and compact ive decided that its actually quite dodgy. Putting 2 ascenders real close to each other and so far away from you has POTENTIAL problems. as you move upwards with each step, there comes a point where both ascenders are close to your waist and at this point if you slipped you could have up too 1.5 m (roughly) of slack to be taken up. I reckon the forces generated by this may be enough to strip the rope or worst case, cut through the rope. The use of the double braid rope (tachyon) probably doesnt help-it really shoulkd be a kernmantle rope so that the strength is all in the core. Im thinking that any srt ascent using a handled ascender(ascension,futura,basic,etc..) really should have some form of chest ascender(croll,duck,vt,etc..) to ensure that a fall arrest situation is not produced. Its the same in footlocking but at least ther you have a hitch with the ability to slide and dissipate the forces. anyone else?

hmmm, thinking that i put too much force on it. If i hadnt of gone through lots of small er branches before the main anchor it would be easier to tell what forces i was putting on it. or maybe just bad luck?

Cheers steve, all sorted.

A little help in knowing what forces we put our anchors under-useful for srt, rigging, etc... angle chart[1].tif

ill give it a go, its a pretty basic chart, cheers for the help.
