Novice question here. What is the difference between an aad and a cypress?
thanks,

A cypress, along with an FXC, are types/brands of AAD.

AAD is an Automatic Activation Device. AAD's will open your reserver (or sometimes your main if you set it up that way) if you pass through a certain altitude at terminal velocity.

Cypres is a specific brand of AAD, made by Airtec in Germany. Cypres is by far the most common AAD because if it's reliability and trouble-free maintenance.

The second most popular AAD is made by FXC. FXC's are much cheaper then Cypres, but the general consensus is that you get what you pay for. Most skydivers strongly recomend Cypres.

Thanks. That is what I thought, but I didn't want to assume and make some dumb ass comment when looking to buy one. My rig came without, so I need to buy one.

This is a little scary. I don't mean to pick on you Andy or Skyrose7, but I continue to be amazed at how poorly most jumpers are educated about AADs and yet how much they are used and even relied on. Yes, they are a valuable safety device, when used properly by an informed jumper who has been properly educated on their use. They even have a great track record with those folks who never bother to learn much more than how to turn it on and off, but they can be and have been a factor in injuries and deaths. Folks, please read the owner's manual. Understand it. Ask questions. Know the design parameters and how it works. For example, the Expert CYPRES is designed to fire at approximately 750' AGL if the vertical rate of decent exceeds _78 mph_, not terminal velocity, which can vary but is generally accepted as 120 mph in a stable, belly to earth attitude. I don't know of any AAD currently in common use here in the US that needs a rate of decent at terminal velocity to fire. Just to get those of you reading this into the learning mode: The Cypres can be "fooled" into firing much higher than the stated design parameter of ~750' AGL. How high can it fire? How can you "fool" it? Hint: The answers are in SSKs website.

How would I become educated about them if I did not ask???

Re: aad/cypress [In reply to] Can't Post

a cypress is a tree that normally grows in teh warmer climates of the world I believe. An AAD is a device that some skydivers choose to wear that senses altitude and speed and acts accoring to it's programed instructions. A CyPReS is an example of one such device.

Re: aad/cypress [In reply to] Can't Post

My post wasn't chatter, I was pointing out that too many ppl rely on their cypress, thinking that it will always save them. Who's to say that it won't work? I thought that I had a valid point.

Re: aad/cypress [In reply to] Can't Post

I think you had a very valid point. I took a bit of heat for just asking the question in the first place. Do a lot of people jump w/out aad's?

Oh no...Here we go....Laugh

Seriously.......I think most people have a Cypres, a few jump Astra or something ancient, and a few (Like me) jump with handles......Smile

Some. Those who choose not to have one generally have a good reason or three.

Re: aad/cypress [In reply to] Can't Post

Alan,

That was perfectly fair.

I did not want to be overly technical in my answer, which in hindsight was a bad idea. My line of thought was that since the quesion was very basic, a less technical answer was appropriate.

Re: aad/cypress [In reply to] Can't Post

Do I have that many? It sucked me in!! I have been surrounded this winter by only WHUFFOs...that can be a stress on me and them. I was quite relieved to find this place... I get to let some steam off. Now, if you don't mind I think I will go search some sites that I can buy more skydiving things on and max out my credit card (again). yay! more stuff!
