I recently bought a rig with an Astra on it. Riding up to altitude yesterday, I looked down and noticed I forgot to turn it on. Let me tell you, I will never forget to do that again. I was nervous as all hell and had a lousy jump. Maybe the more experienced jumpers will disagree, but I think that once you have jumped with an AAD you will never be comfortable jumping without one. I heard one guy with thousands of jumps saying how he didn't need an AAD because he's "never forgotten to pull," but I'm more concerned about dying while trying to pull but not being able to get it. Just talk to somebody who has had a cypres save in person, and that (short of having one of yor own) ought to be enough to sell you on them. As far as these people who say theres no point to them and they are unreliable, forget them. Anything you can do to increase your safety is a good thing. Thats why I choose to jump with an audible, 2 altimeters, and an AAD. Anyways, sorry for the long post but it was on my mind today and glad to see the topic come up.
