navigating with SRT TIP

I'm having trouble visualizing changing the TIP when climbing in a tree single line. You have to get the free end and pull it around with you, then loop it over the next crotch and feed the line down. . .am I missing something?

Do people change the TIP much when single lining? I am often high enough with the original TIP, and can do all the work from there, swinging around with a RADS system, after climbing up on a tree frog kind of thing.

Can you have a falsecrotch for the SRT line, and just take a bight of the rope with you when you want to go higher or move to another crotch, and hang it on a sling or something?

Just wondering. Can't remember living without SRT. . .
 
You can change the SRT much like one would change a split-tail DDRT - lanyard in and advance the same end of the rope, or some people like to do a double end advance, in which case, as you said, you feed the free end over the next TIP, and then you have two options:

One you can lanyard in and switch all the gear to the rope on the new TIP, or two, you can hang from the foot ascender via a tether (RADS) while you remove the Grigri and install it on the rope on the new TIP. Then stand up and tighten the grigri to unload the foot ascender, and transfer it.

Of the three methods, the single end advance is simpler; you don't have to remove the pulley and biner from the foot ascender and reinstall it all on the other end. You also don't have to remove the grigri and reinstall it.

I have however, used two grigris and advance double end. Although I did that all the way up to the top, 100 feet, I didn't like that method much - too much gear and stuff in the way.
 
Just yesterday afternoon I had to advance my TIP once I got into the tree. A better TIP was up and to the right from my access TIP. All I did was lanyard in. Detach my Unicender. Pull up the running end of the rope, install it higher, reattach the Unicender, test my new TIP with a bounce/set and finish the pruning.

Resetting a TIP with SRT is so much easier that DdRT.

When I got to the ground my rope cleared out smooth as ice.

Jeff and Ron,
Can you pls clarify if you are talking about a choked or ground anchor in each situation.
Cheers

I use a limb cinch if at all possible. The ground anchor makes rope advance a bit more complicated and sometimes a bit restrictive, plus, you can run out of rope - 75' ground anchor pretty much uses up a 150' rope.

Sometimes one simply cannot avoid a ground anchor to get into a tree. My first preference would be to use a ground anchor technique that I can release from the tree and recover the rope. It is a perfectly safe, well as safe as tree climbing, and doesn't involve some kind of slipped hitch. The downside is that there is a slight chance that the rope can get snagged and not release.

A second method is to use a ground anchor for entry and then use a second, possibly shorter, rope to advance once you reach the TIP.

That's my main technique for tall conifers. For hardwoods you can usually cinch the anchor and then make a decision depending on what you're trying to accomplish whether to advance the SRT TIP or convert it over to a DdRT system for working the crown.

Remembering that this is a work climbing context, ground anchor w/rescue potential built-in (as Tom has been talking about for a while) seems like the smartest way to go.

I can see it now - thank you all. I'm usually anchored on the ground, (and often bring a smaller rope and advance up higher with it - all too often in some sticky fir. . ), and can see how that makes things more cumbersome. I'm picturing climbing high in a spreading canopy and moving laterally and up to get a higher TIP, like Tom's describing. Just pull up the end, don't drop it, and loop it over the next crotch and tie in below that.

I'm hooked on this Edelrid Eddy device for SRT - will they let me use it in the TCC? I don't have a unicender (yet), but can you use one of them in a TCC?
 
I would allow an Eddy...no reason that anyone else wouldn't, or shouldn't. There have been times when the people doing the inspections aren't up to date on gear so they don't allow some things. The best thing to do is bring the product info along, either in your phone/PDA or printed. You could also bring the links on the Eddy from Treebuzz too :)

How are you using the Eddy?

Do you have it rigged 'upside down' so that the ground end of the rope goes out the bottom? If so, you can tail the rope really easy from limb walks. YOu can also 'thumb' the cam to limbwalk out. This makes it soooo smooth!

Paolo and I tried to test to see if we could thumb the cam but still trust that it would go over-center to lock if we fell. We came up with a simple test that convinced us that it wouldn't compromise our safety.

Let me know if you're going to buy a Uni, I'm a dealer now.
