I got one, plan was as an Audible as they have they 99 slots with start and stop altitudes, sounded fun to experiment with. I use a Phantom X full face which has an internal audible pocket in the lining. The ION is WAY too thick to be used as an audible, it was like putting a brick in my lining, uncomfy and not safe if i banged my head with it in there. Had to switch to it as my main alti and my old thinner neptune as an audible. I imagine helmets with an outside audible pocket will work fine with it. Also they logging is still non existent. Cant track what jump you are on, randomly adds garbage entries, even the real ones have the wrong freefall speeds etc. As an altimeter, its cheap, it works. But its a work in progress.

We ran a POPS 16 way sequential jump lat summer (15') and we're missing information on one jumper. Jeff Sanders from Kennewick WA area, retirement age. No contact info I have come across is current. Does anyone know Jeff (Pictured back row far right, if the upload works)

Here's a technical article on it to explain to his scientific thought process. http://hypertextbook.com/facts/JianHuang.shtml Basically though heavier objects and small objects experience less air resistance and fall faster then light or long lanky things with lots of surface area to produce drag and resistance.

I agree check with a doc first, but then assuming its just sensitivity to the air pressure.. I went through a phase where Id get some bad migraines like you describe, though usually the next day. At first I assumed the Valsalva maneuver was pushing air pockets back into my sinus and avoided it. Next when that didn't consistently solve the problem, I moved to trying airplane earplugs to stop the sinus problem at all. That was only minimally effective, and they were a pain in the ass to wear under the helmet and deal with each jump. Final solution is what worked for me, just being religious about chewing gum during the ride/jump, so that im equalizing the pressure, the entire skydive. Rarely I still get a touch of air sinus sickness, but my limiting the buildup up pressure to begin with, the problem is all but gone even with 6-10 jumps in a day.

Seems they thought of that. This video's linked off their Facebook page, showing a whacker opening. 7.5Gs!!! https://www.youtube.com/watch?v=-n05tgI5oR8

Sorry to inject of your thread but its here already. I also am having a problem getting dialed in, first few days trying it out (Replay Mini HD 1080 on a Benny Helmet). Bit of advice I got around the DZ was top mount a bit higher then level (Tried that and on inside video it was aimed too high. More likely a good setup for outside video). Then tried sidemount, mount spot its just under the eyes tilted back up a nudge to be inline with eyes. Those ended up too low on inside video. I realize a lot of camera work is aiming it by orienting your head in relation to where you know the cam points (Rings for instance). So a lot of my problem is noobness and not having learned to keep head a tad up or a tad down. Replay mini has no HDMI out, you have to download to view so sighting in realtime isn't an option. Are there rules of thumb for inside video and outside video, like standing 10 feet back from a wall standing up should record centered same height as your eyes? or lay down on a creeper 6 feet from a wall and check what your recording is centered same height as your eyes? Or just dead center top mount perfectly centered and level and just learn to aim ones noggin more? Cheers 'Femur' Ron

This sounds to me like a tension knot on the right side. The 4 brake lines coming off the trailing edge tend to get spun and twisted after a few jumps. (Some more so then others). Left unchecked it causes the knotted up side to get shortlined and your symptoms happen. Few pumps has fixed the few I had, but of course you cant do that with line twists. I had this happen a few times on my new canopy Since then I'm in the habbit of checking every pack job, and walking my brake lines every 3-4. Since getting religious about it ive had no more of those type openings on my Trialthlon 160. Pro Tip from a friend: Look up under canopy once in clear air and if you see twists, deal with them in flight. Under load they untwist easy.

We have the Piper Navajo down at Skydive Toledo. Come on down any time John.

Had a slammer opening on my 5th (cat d) AFF jump that completely broke my femur in half in June 2011. Canopy was trashed and I cutaway with the busted leg. After I landed with the busted leg, the main thought in my head was 'OMG will I be able to jump again.?!" (Slammer caused by me going stiff and scared and into a dead flat spin , dearched on my back come pull time, whiplashed my leg at the strap). I would have jumped again the next day but alas broken bones heal slower, slower yet in your 40s. Took 10 months to be truly cleared by the doctor (Bones didn't set very fast). As soon was I was cleared I started a S/L program to slow things down, especially opening shock a few jumps with the new metal in the leg. Still jumping, still having the time of my life, just passed my B and at 78 jumps now. 1st Jump I was hooked and not much would have stopped me from living the dream... Ron - Blue Skies
