Slider Up

[guest]

I have only four BASE jumps and I'm going to jump mesh slider up for the first time at Bridge Day this year. I know of direct and indirect slider control. Is one way better than the other? What is the best way, or is there one? I would like some imput on this. Thanks

There's isn't any one accepted way. I use just direct by bungeeing to a c-line but everyone I jump with does it different ways. I don't think it's a major problem which way you do it as long as you do have some control of the slider.

I'm going with NO slider and a 45" pilot and a three to five second count depending on conditions.

DO NOT rubber band your slider at BD2K.
You can easily take a 5-6 with out a rubber band. Chances are you will take a 2-4 second like everyone else. NO EFFENSE! But most people take between a 1-5 second delay at BD2k. So there is NO reason to try to slow the opening down by altering the control.

"and this is obviously why we have a seminar to address such questions"

Remember there is NO such thing as an ignorant question, just Ignorant jumpers who decide to jump without asking.



This years seminars are for you to ask, listen and add your input.
The BDA has spent much time and effort in this regard, please take time to attend.....your input is important.

I don't know about anyone else but the reason I control the slider is not to slow the opening down but to ensure that it doesn't begin to come down the lines until full line stretch. I do this to stop the possibility of tension knots which I think would be a whole lot worse possibility than a slightly slower opening with a conservative delay.

Anybody else care to comment - I'd like to know if I'm doing something that everyone thinks is FUBAR!

Cheers,

3 - 5 slider down with a 45.

Dubious choice in my opinion.

People, please give your input on this subject... I'm taking 6 sec. from 1000' with no direct slider control... I'd like to know what luck people have had with similar/different methods.

i have been using both direct and indirect slider control on anything offering 4sec delay or more...towers >200m.

the combination seems to give a more evenly staged opening than trusting the indirect control via the locking stow by itself at higher airspeeds.

Hi Mick -

I have a completely different view than you. Not that my view is right, but simply my opinion from my own observations and test jumps.

I have made 114 slider-up jumps with both direct and indirect control on the slider. 68 of these jumps have been made 480ft or below with direct observation of the "direct control" of the slider and it's effects on low-speed slider-up deployments.

I am confident that my rigging of direct control actually *speeds* up the deployment process. 68 jumps is not quantitative by any measure, by it has been very apparent so far.

My theory (and it comes from Adam Filippino) is that direct control helps to ensure that the slider is not released until you have complete line-tension and bottom-surface expansion begins. With the lines taught, it helps to prevent slider-induced tension knots as well as providing a tight, clean path for the slider to "rocket" down the lines, therefore providing a faster deployment sequence.

But once again, this is simply my view. I'm not saying this is THE answer - rather my observations.

BDA has a really good point. They are going to great lengths to provide very informative seminars from EXPERTS in the field. (which I am not)

So I would definitely attend with an open mind to what you may think you already know - because others may share a different view.

Also, please don't take this as a harsh post. It's late and I'm mega tired!

Have fun and let's all party hard at BD2000!!!
