opening shock
As a recipient of shoulder surgery some years back, and having not done a basejump, please forgive this if a) there are threads to search this on OR b) its a stupid question. How hard is the typical opening shock on the average slider up jump? What about slider down/off?? I've owned a couple of Sabres loaded at 1.5 - 1.7 ish and had my neck hurting for days on end sometimes from the crap openings. I've never been sore after any of my reserve openings (3).

Thanks in advance.

Re: [freakydiver] opening shock
Speaking for myself here, I personally don't find any of my BASE openings(slider or not) being anywhere near the shock I used to get from some of my Sabre openings.

But I'm sure everyone here has their own tolerance for hard(fast) openings. Mine happens to be high. It's part of the whole experience for me.

But keeping in mind that the general rule is not to go more than 3 seconds without a slider. Anymore than that, and I'm sure they would cross the fine line between pleasantly brisk, and painful.

I remember my first slider off jump how after I tossed my pilot chute and prepared myself for what I thought was going to be the "opening from hell", actually turned out to be not so bad. And haven't been since.

(now watch, tomorrow night I'll probably get my ass slammed!)Crazy

Re: [rfarris] opening shock
I have a bum shoulder, ok I have two bum shoulders but my left is much worse - most of the rotator cuff assembly is torn entirely off the bone. I was told two years ago "don't do anything physically demanding, schedule surgery at once, take it easy in the meantime, and get ready for 6+ months of rehab." Of course, I ignored that.

I've dislocated that shoulder twice during deployment, both slider-down. That is not fun; both delays were in the 3-3.5 range. After those incidents, I learned to basically cross my arms after tossing the PC to hold my shoulder in during opening shock. Not very stylish, but it works.

BASE deployments slider-down in the 3 - 4.5 range (particularly above 4) can be very, very punishing. I've had partial blackout at the 4 second range, and that's jumping old Mojos. Take 4+ with a new-ish, vented canopy and the damage goes up exponentially. I'll still do it sometimes, but the body load from those sorts of delays is truly punishing.

Yesterday I took just shy of 4 and cleverly forgot that I had a nearly-new, vented Troll 290 on my back. My neck is quite sore today, along with shoulders and (mysteriously) abdominals. I think I know those delays well enough that I tense my body and prep for the pounding. Staying loose sounds good in theory, but for me I need to fight that shock or I'd end up doubled over in a ball and not very functional for dealing with potential off-headings.

The worst pounding I've ever taken was a 4.3 second delay where I got very head-down. Pack job came out of the container and hit my feet on the way to line stretch - not optimal body position, to say the least. I opened with a 120 right and half a line twist, along with blacked-out, tunnel vsion. I kicked off the cliff, got setup for landing, and somehow got down safely. I hurt for weeks afterwards, and was scared of that object ever since - I still am!

I don't think many folks are into taking 3+ second slider-down delays consistently. There really is damage as a result, not just in the neck but in the lower back. The visuals are fun on some objects, but I'm much more picky about when I'll go deep now than I was in my "young and stupid" days. Now, I'm old and stupid!

I think it is possible to pack so that slider-up deployments aren't horribly punishing, consistently. However, I know of no safe tricks to really soften 3+ slider-down. For those, we just grin and take the pain.

Peace,

Re: [Dd0g] opening shock
From up top, I swear I saw your feet swing out from under the canopy when it opened! Wink

Re: [Dd0g] opening shock
I were wondering,does BASE manufactures make a test on the systems,like TSO?

If so i could legal skydive my Fox in Denmark(ie no troubel at the dz,which i have enough of)
Shortcut
Re: [Faber] opening shock
As far as I know, there aren't any BASE canopies that are TSO'd. It's a pretty expensive process that's hard to justify. Especially here in the US where even our skydiving mains don't have to carry a TSO. We can pretty much stuff anything in a main container and jump it as long as the reserve is good to go.

To clarify, to jump a main in Denmark it has to have a TSO? ---Dex

Re: [Faber] opening shock
I believe the Mojo was TSO'd (or whatever the equivalent certification is) in Germany a few years ago. This is the only case I know of where BASE gear has actually gone through a certification process for general skydiving.

You might try contacting CR for more info, as my memory of the details is fairly hazy.

As i understand the rules yesUnsure

Re: [Faber] opening shock
If thats the case then you can't jump any of PD's main's since they are not TSO's.. only the reserve's are. Ame with Icarus mains, and Big Air Sportz, and well.... I'm yet to see something other then a Raven be used as a main that's TSO'd.

Re: [PhreeZone] opening shock
That's what I suspected because most mains don't carry a TSO.

I think this may be a trans-atlantic miscommunication. As I understand it, there are several non-American parachuting jurisdictions that require a "TSO-like" certification for mains, as well as for reserves and harness-container systems.

I believe that one of the German BASE jumpers took a harness system through the German TSO-like process, because the German USPA equivalent required it before they would co-sponsor BASE days held off some of the local towers.

Re: [PhreeZone] opening shock
As i said as i understood.. I´ll find out exactly tomorrow.I´ll post the answer here..

I hope your rigth,so i can skydive my Fox when i get back(need theese new brake and so on).

Only asking while my dz is werry much against BASE,and im just a newbie that dont want to step on too many toesWink

Pointless factoid alert... PA also TSOd the Falcon (maybe hoping to start a new market for nine cell reserves?).

after a deeper reserch i found out that the only thing that dont need to be TSO tested is a main canopi,meaning that the canopi just need to be cleared by a rigger,if you want to jump it in DK..

This info comes from my local rigger

Re: [Faber] opening shock
Hey Faber-

Just by way of clarification, I think it was a Perigee of some model and a Fox that was TSO'd in Germany.
