Altitude Awareness Can't Post

I've crossed over to the dark side just a couple of times, and I'm curious about how to check your altimeter. I've tried just glancing over at my altimeter, but then I start spinning. I've tried bringing my arms in to look at it, but that's just not happening either. It's easier in rw dives just to glance at other people's altimeters, but since I rarely see anyone in my sitfly jumps, I can't do that either. Any suggestions?

check out www.skykat.com and a device called the wedge. I love mine!

I have seen sit-suits with the altimeter mounted in a pocket on the knee.

Skydiving is not a static excercise with discrete predictability...

I don't know if you are head down or in a sit, but for me in a sit all I have to is keep my arm strait and bring my hand up. Then all I have to do is turn my head and I can see it without any problems.

I put my altimeter on the side of my wrist. More like on top of my thumb. (I have three fingers thru the little circle thingy.)Then its barely a glance and quickly to avoid the spin cycle. But, go ahead and learn how to counteract a spin or counteract anything. You will need this information later.

Anyone here use one of these? I think it would take exactly one missed landing to convince me that this is a Bad Idea.

An audible is always a great back up to your altimeter. Wink Especially with the increased speeds of freeflying. Cool

Re: Altitude Awareness [In reply to] Can't Post

I see a lot of the really experienced people mounting them on a wedge at the mud flap. I still have mine on a standard wrist mount. Just practice looking at it until you can do it without spinning in your sit. OK.....now figure out how to look at it while Head Down. I remember the first time I managed to check my alti while head down without being unstable. It was an accomplishment!!!!! Smile

You can put your hand in front of you as long as you counter-act this with the other arm behind you......... it takes some practice...........

Which is why I had my grandma get me a Pro-Track for Christmas (I've got the best grams...) I've also heard that you can put your altimeter on top of your shoe. I'm afraid that if I biffed it in, however, I'd have to spend another $100 on an altimeter.

Re: Altitude Awareness [In reply to] Can't Post

I've heard that a chest mount isn't good for FF due to the burbles it would in. I've been using one for a while now and it's been fairly nice, just a quick gland down to see my altitude.

Is it inaccurate due to it's position?

"chest mount isn't good for FF due to the burbles"
Good and valid point Aggie, Pat Works suggests a wee bracket thing on the ring cover, similar to the Skykat wedge and used to have a DIY guide for it on his website. At a guess, the burble is only really gonna put you out by about 500 ft max. With most early F/F breaking off at around 5k, I don't think its that critical. IMHO really accurate altitude management is more important at pull time. ie its imprtant to pull at the planned height, not too low, and equally not too high. To me this (the time between break off and "minimum decision altitude") is the most critical part of freefall
Personally, I supplement my wrist mount with two audibles (throwback from my 2-d camera flying days), but am considering the wedge thingy or similar.
The chest mount should be ok if its pushed over to one side or the other, or it should be a simple mod to put the chest pad on the ring cover with some wide velcro straps.
I'm low time sit/stand, but some of my drills have been doing alti checks between other moves (hey, it works for AFF!). Sooner or later you will have to start moving your arms about to take grips, geek etc, anyway.....
2 cents worth....for what its worth!

YES...in fact the last time I jumped I did a 3 way hybrid. I noticed on break off and pull time that the two belly fliers alti's were off due to spending several thousand feet in my burble. (I was in a sit/stand beneath them) One of the belly fliers says he pulled at 3500. I had planned to pull at 3000 but since I stayed in a sit to watch them leave I knew my air was clear and dumped at 3300. They both ended up below as the canopies opened.
I think putting it up on the Mud flap instead of the chest strap alleviates most of the burble problem.

Should be no problem if you're head-down or sitting properly (torso near-vertical) or standing. There will only be a real burble on your chest if you're lying right back or purposely back-flying (arms and legs pointing up).

Re: Altitude Awareness [In reply to] Can't Post

Actually, in a proper sit, a center mounted chest mount is going to be in the middle of your burble.
Try this one once to see where the burble on a sit is.... tye pull up cords to your jumpsuit in various spots and watch them in freefall. The ones that are straight up are in clean air, the ones that dance all around are in the burble.
I discovered the burble is actually quite large on a sit flyer by flying for a totem and falling on thier lap beacuse I hit the burble from thier legs.
Turbulent air flow is what causes the altimeter to be off, it can't properly sense the air pressure if it keeps changing.
