On a discuss.

On which type of jumps can you best plan and do a low pull?
Meaning lowest canopy opening.

On which jump is the most safe for a lowpull?

werry simple,please only chek 2 boxes.

I see 57 votes but no replies...

At first I was going to vote slider down because
simple is usually more depenable then I realized
I have no business voiting since my 7 jumps were
slider down, on heading, and none were low pulls.

However, I am very curious to hear the rationale
for the different popular replies from you experience
guys out there. Thanks in advance for the education.

 
quicker, more reliable opening that can be gauged for distance used better.

I think it depends on your definition of "low pull."

I'd go with slider up, short delay, over deep water. This gives you the most margin for error (since the water helps if you pull too late), the most "survivable impact" time (since almost any time after the slider begins coming down is surivable, but will still impress your buddies as a "low pull"), and the easiest reactions/judgment on when to pull (because you are moving the slowest). It's also likely to give you the best groundrush, because your impact speed can be the fastest (while still survivable), yielding the best visuals if you can impact while the slider is still only part way down the lines.

Again it depends on how you define "low pull" though. If you go with "full flight before reaching the ground" or "lowest pull with a stand up landing" or even "most freefall time per canopy time" your answers may vary.

Slider down, canopy opens faster (uses less altitude to open and vertical speeds are lower so it is easier to judge.

Is a Freefall from 160ft automaticly a low up??

By some standards our last freeway overpass static line jump would be considered a low pull...
freefall 0.5 sec...
canopy time 0.5 sec.

That's a descent ratio for a low pull

and yes... Greeny's throw and go's have got to fit hummin' it standards!!

well i think the poll speaks its own word..

the thourght were jumping over hardground.
There were no definition on the lowpull as it were thourght as over hard ground(i know i didnte write above sorry).I define a lowpull as a jump were you pull as low asposible over hardground and still walk away

No Greeny ff off 160ft aint a lowpull unless you make a delay

Subterminal round over water.

If you're jumping over solid ground, isn't it safer to reduce vertical speed by tracking hard?

Also: If you go on a terminal tracking jump with slider down/off, will you/your canopy survive?

I guess it's the nature of the jumps I mostly do. But I usually find myself behind where I could pull high before I even launch.

I just try to fit in a deployment, after I leave, and before I hit the ground.

Isn't that what everyone else is doing?

I know the Norvegian Stig did a terminal slider down and survived. His body was sore for a couple of months but no broken bones and no canopy damage. Pretty amazing!

There is a regular poster on this forum who famously did a terminal slider down jump off a big cliff in California. The resulting injury, rescue and arrest are also quite legendary.

moron didnt roll his nose, he would have been fine.

low pulls are cool u need a solid 2 sec delay from 300 feet stowed and im not talken about talas i mean concrete or pavement

What if i jump from 190 and pitch after I clear the rather large ledge at 173??

(no it wasn't on video and I'm not sure I ant to do it again)

Greeny

While preparing for my FJC I accidentally took a Mojo 280
out of a cessna, slider down, packed in a Publix shopping
bag. After the lightning fast opening I spent from 3,500 till
1,500 just hanging in the harness and moaning.

I could not image taking one terminal --- ouch, damn!!
So was it an accident or a stunt?!?

what was ur exit airspeed?

exit speed?

If I had to guess I would say 40 knots

-------->edited to add:

I just did a quick search and found out that
49 knots is a cessna's stall speed so I guess
the speed was probably more like 70 knots.

When you're low, you're slow. Doing terminal low pulls is by far the most challenging jumps that are possible in my opinion. I was finally able to get a 7.2 second delay at Bridge Day on both of my jumps there last year. I have finally gotten to the point that I can open at around 150 feet from terminal towers (2000 feet). However, it's gotten to the point that I'm having to raise this altitude since it's only a matter of time until I bounce.

Speaking of terminal opening slider down, my friend John F. took his already packed skydiving rig to the DZ, back in 1984 or so. Unfortunately, he didn't realize the rig had been packed slider down by Steve Morrell (BASE 175) for a bridge jump. John opened after doing a regular airplane jump with that slider down rig. It blew out a couple cells and jump stayed slumped over all the way to landing. He was too afraid to open the reserve because he realized his body could not take another opening shock, no matter how gentle.

well i guess ill take your worth for it and no i wouldt do it either
good work
we need to hook up some day
