slider up/off delay

[guest]

Hi again.

I was wondering how much altitude you loose by using a mesh slider compared to a slider off.
Surely this depends on the slider itself, the packing etc. but I just would like to know in which size group that takes place.


thank you

Have you looked at the gear/altitude/delay chart on the Basic Research web site? That would be a good place to start.

Yes, I do know this chart, but it doesn't really answer the question.
On the chart are the recommondations what gear to use, my question was more like how much does a mesh slider actually slow your opening down and how much height do you loose that way.
The only source I have are some videos, but that's not a very good foundation.
So I thought that maybe one of you already figured that out :-)

The decision on whether or not to use a slider must be made with consideration to several factors. Some of these factors have little to do with simply how much altitude the deployment will take.

Sliders will affect your deployment differently at varying delays. Using a slider with too short a delay will probably have negative results on your heading performance. Going too deep without a slider is a bad idea for more obvious reasons.

Once you are within the appropriate delay range for using a mesh slider, you can have varying results in opening times that have more to do with the canopy type, packjob, etc.

I think you want to know a hard number for vertical feet consumed during deployment. This will vary according to your equipment configuration and the factor I listed above. I'm sure you know from skydiving that openings can be quite different even using the same setup and packjob. In this game you need to work out what your gear likes to do, and try for as much consistency as possible. Just because someone else is getting openings of a certain type, doesn't mean you can count on getting the same.

Learning to BASE jump involves a lot of learning. There's a terrific amount of information you will need to make wise decisions in this sport. Sometimes reading about BASE technical stuff can seem like swimming through a murky pool. As you learn, more and more will become clear to you. Ask questions and read everything.

Also, on the vertical feet thing... Whereas in skydiving you might be able to make a statement like, "My VX46 takes 1500 feet to open", these statements are grounded in the fact that almost every skydive is the same in the sense that you're assuming a terminal deployment. Aside from the fact that this means you're deploying with the same vertical speed every time, there's also the fact that the 120 mph vertical speed will (unless you make a habit of jumping in 60 mph+ winds) drown out any effects due to other winds.

In most cases with BASE jumping, I don't think these simplifying assumptions can be made. The time it takes you to open will have a lot to do with:

- Delay you take
- Wind conditions
- Altitude of the jump (ASL)
- Temperature
- The exact gear configuration

Also, as Dex mentioned, there are a lot of things which are often more important to consider than available altitude.

That's almost what I expected although I thought it would maybe be possible to name a rough value.

nevertheless thanks a lot!
