A comparison: Eddy and Grigri (video) + I\'D pics

This is a discussion/comparison video; it's about 8 minutes long. I make some references to videos where I'm climbing on the Eddy, but I don't have those on YouTube yet, but here's a good starting place:

Oh, before you watch it, it's gonna be oriented upside down to you - sorta. I don't think it'll be a problem, but 'up' and 'down', 'left' and 'right' references are with respect to my position which is unfortunately opposite of you. I had to shoot it that way to avoid shadows and arm, head, and hand blockages.

And I should have mentioned two other things: one, the Grigri weighs 7.9 oz; the Eddy 12.7 oz or a difference of 4.8 oz. And two, it is not easy to tether either the Eddy or the Grigri to prevent dropping it. The Cinch, OTOH, is a cinch to tether.
 
Re: A comparison of the Eddy and the Grigri (video)

I want to know the difference between the Grigri and the I'D I was curios how they treaded and that explained it. So I take it that the I'D does the same.
 
Re: A comparison of the Eddy and the Grigri (video)

I'm on Spring Break, as I presume you guys are too,

so I've got a little more time than usual so I'll try to do an I'D report. I'Ds are often short-changed because they are big, but they do have some nice features and advantages.
 
Re: A comparison of the Eddy and the Grigri (video)

Thanks for taking the time to make and post the video!

The Eddy has a unique feature that sets it apart from the GG. The release can be used in pull, like you showed, or in squeeze. In many configurations for climbing squeeze works smoother. It takes a little time to learn how to feather the release but once that happens its as smooth as any well-tuned cord hitch. Letting the handle go locks off quicker than in pull mode too.
 
Re: A comparison of the Eddy and the Grigri (video)

Hmmm, I'll have to try the 'squeeze'! If I can figure out what it is. But, there aren't too many ways it can work, you either pull the lever down, or you lock it down and push (squeeze) it upward.
 
Re: A comparison of the Eddy and the Grigri (video)

Well thanks a lot Ron! There are alot of things that I want, but it is so far between when I can squeze them. So it really helps to see how they work, and the benifets, Thanks agin!
 
Re: A comparison of the Eddy and the Grigri (video)

OK. Well I watched your vid. and then a couple of more on youtube were people was working the Grigri. I was under the missconseption that the Grigri wasn't a descender, because in the Sherrill catolog, it says "THE GRIGRI IS A UNIQUE BELAY DEVICE" I just landed some work from my friends mom. So I was thinking that I would see if I could just make an order for a couple hundred dollars. Like I said I had been wanting the I'D, but if the Grigri will work the same for a hundred dollars less than I could get the Big Shot too. So any way for the money it is a good descender, and assent system? (I have CMI handle, and Micro pulley) If I get go with the Grigri, I should be happy with what I spend? And I haven't seen the Eddy. Where can you find it and how much? Thanks agin!
 
Re: A comparison of the Eddy and the Grigri (video)

The Grigri makes a good a RADS setup. However, the Eddy is about $115 and the Grigri is about $95. Both can be used to belay, ascend, and descend. Both are much smaller and lighter than the I'D and much less expensive.

You can buy Eddy's and Grigri's are lots of places. If you want the Grigri, On Rope has them and they are a mamma-pappa shop I can highly recommend.

I don't think the carry the Eddy, but Amazon.com has them, REI, and many other places. I'd try to find someone close to you to cut down on shipping time.
 
Re: A comparison of the Eddy and the Grigri (video)

Besides Ron's generous contributions to the discussions there is another place to learn about going up and down ropes.

Anyone who spends time on rope should take the time to read through all of Gary Storrick's work.

http://storrick.cnchost.com/VerticalDevicesPage/VerticalHome.shtml

There is soooooo much history there. You'll see rope tools going back to the early 60's. Having an understanding of how the current tools were developed will give any rope worker a better understanding and appreciation for what is available now.

Read and find out how racks lead to the Unicender. Munter hitches have lead to the Eddy and I'd. Hot seat rappels have lead to F8 tools.

Instead of us doing your homework, I don't mean to pick on you Chris, and you'll know much more.
 
Re: A comparison of the Eddy and the Grigri (video)

Thank's Ron those was a couple of nice videos there. Very nice demo's! I got lucky and had someone e-mail me, and is going to let me try out the Eddy and the Grigri. That was a real generous offer. But your videos and post have been very useful for me, so thanks! And thanks to Tom for that link and advice! I checked out that site, and I liked it. It is going to take some time of going through just to get a start on it. I couldn't believe all the things he has. I would not even imagined it. I do I like reading and researching when it comes to climbing, but sometimes don't no where to start. So I do appriceate it when you guys post links like that!

What's the major difference between the Eddy and the I'D?

Chris,
The I'D is huge; maybe I can post some comparison pics shortly.

The I'd has some nice features, including a panic lock, protection against threading it backwards, and on the "small" version, (10mm - 11mm ropes) it can be installed and uninstalled on the rope without disconnecting it first. A Grigri and Eddy have to be disconnected before they can be installed or removed from the rope. The I'D also has a work position lock off. You simply position yourself and rotate the handle to the lock position. It'd hold just fine without that, but the work position lock adds another level of security.

The I'D is expensive and big, i.e., about $225 (On Rope 1 - onrope1.com ) for the newer version and I don't believe the earlier models are available any longer, although, On Rope may still have a few earlier versions in stock for more like $180.

Re: A comparison of the Eddy and the Grigri (video)

Tanner,

Storrick is an interesting resource, but keep in mind he is cave oriented and I'm not sure if he's had any tree climbing experience and especially not arborist experience. And, before that's misunderstood, all I'm saying is that much of his evaluations are based on the suitability of gear for caving.
 
Re: A comparison of the Eddy and the Grigri (video)

The I'd is rated for a two person load since it was developed to fit the niche of rope rescue. This is a point that is routinely glossed over in arborist rescue.

Agreed, Storrick is cave based. Sometimes he misses an application that we use for a particular tool. He had gotten some arbo tools and does admit that he doesn't know how they would work, either in caves or trees. To me, that is a good sign.
 
Re: A comparison of the Eddy and the Grigri (video)

What a guy that Ron, ask him a question and he don't stop until he shows it to you! I think that I see the major difference. The Grigri, doesn't have that smaller piece that the line goes around. I don't no if you would call that a cam? But I am taking it that is why you make a loop with the Grigri, because it doesn't have that like the others?
 
Re: A comparison of the Eddy and the Grigri (video)

Tanner,

The Grigri and I'D thread exactly alike; the Eddy threads differently as can be seen here:

The 'little piece' at the bottom of the I'D is a safety that would catch you if you were to thread the I'D backwards.

The 'little piece' at the bottom of the Eddy is a wear/friction block for the down rope. The Grigri and I'D have a lip at the top that serves as a friction/wear/guide for the down rope.
 
Re: A comparison of the Eddy and the Grigri (video)

Great info, Ron. Tanner, if you are contemplating purchasing this type of tool do not overlook the Petzl Rig. I have not used one yet but it is getting great reviews.

Thanks Dave.

I looked at a Rig, more accurately, Jen at On Rope drug me over to the rack and showed it to me. I went back later to buy one and then noticed it's spec'd for 10.5mm - 11.5mm rope.

So my 10mm HTP is too small and my Lava and PI is too large. I think the PI/Lava size rope would work, but I haven't tried it and haven't seen any info about using it with ropes greater than 11.5mm.

You heard anything about that?
