Its correct that the Tandem Cypres activates itself at 900 m. But it will still be activated even if you drop below 900 m, if i understand it correct. The deactivation altitude on Cypreses (except speed) is 130 feet or ~40 m. If your static line jumprun drops below 40 m, then yes you have two problems.

Hmm.. Good idea. When you log the data that could work, but when/if you manipulate the already loged data it could be harder. But i looked at one of my jumps with Flysight, and i think the horisontal-, vertical- and speed-accuracy could be used combined with the number of satelites. The H and V accuracy was about 4 m during the jump, so if i would use a threshold of 7 or 8? When i have a larger sample of loged jumps i will start with that. Thanks for the idea!

My experience with creating a frefall detection is that its really hard to make it work with GPS devices. I tried to make a code (to my other GPS, not the Flysight) that removed all the airplane and canopy data. If i remember correct i made the code react on altitudes above 2000 meters, vertical speed of 100 km/h, looking at the other nearby vertical speeds and altitudes to make sure its correct numbers, and vertical speeds dropping below 50 km/h. But because GPS devices sometimes get wrong data it could sense that i was in freefall when i was not. And basicly if i changed the code to make it work on one of the jumpdata it would not work on the other because of that change conflicted the data on the other. I have thought about trying to recreate it for the Flysight, but my previous attempts for my other GPS kind of holds me back. The Flysight is more stable than my old one so its probably going to be easier, but EDIT: one of the biggest challenges with GPS devices is when you turn them on and they start looking for satelites they are not accurate for S***. And thats one of the areas where you get problems with freefall detection. Other troubble areas is loosing connection with one and geting connection with another, this can create a "bump" in the data. But ofcourse, this was with my old GPS, i have not tried it the Flysight.

that was too far away, i could not read the serialnumber on the canopy.

I agree with the previous poster about asking your intstructors. Pulling the main while on your back might work, but there is a big risk that you get entangled in lines. But that is better than not pulling, every second in freefall eats lots of altitude. Talk to your instructors. We had a fatality like that in 2002 at our dropzone. Dont do it.

Last time i looked at their website it said september this year.

i see you caught your miscalc. i was gonna say, i just checked my neptune and i have 6 hours of canopy time. 6 hours of canopytime at 155 jumps? Did you use the neptune from jump 1? Im only asking because of the canopytime per jump on average. My calculation was 5 min per jump, but i think that is to much. I would think 2.5-3 min is more correct, but 5 was easier to calculate

Yup. It scares me too. Over here we have a 500 jump limit, after 500 jumps you can jump whatever canopysize you want. And some (a lot of people) think that is too much. 500 jumps equals about 4 hours under canopy. Who thought they knew it all after 4 drivinglessons? Edit: just realised i missed one zero during my head calculation there. It probably equals about 40 hours not 4. But still, its not that much

I had no idea you used In/hg in the US METARs. I thought it was the same all over the world. In that case the METAR should have one part saying AXXXX where the X are numbers. You could use this map and find the METAR you need, and you can change the units to make it display the numbers in hPA in the decoded version of the METAR http://en.allmetsat.com/metar-taf/north-america.php

Primary goal...figure out if I've got the right settings going on. Does what said earlier mimic how it should be set up? I've done a few jumps with my Core and a Galaxy II. They pretty much agree. Yes, when I'm in the loading area I set the ref alt to 0. What is your current setting for sea level? Mine is 972 hPa. A quick google tells me that at 15C it should be 1013.25 hPa. You googled a general pressure at 15C at sealevel or where you are right now? If you want to compare the airpressure with your Suunto i suggest you look at the METAR at the closest airport. The METAR should have one part with QXXX or QXXXX where the X's are the airpressure. Also look at when the METAR report was made, if its a few hours old it could be off.

The altimeter basicly only tells you how much air is stacked above you right now, and the numbers on the altimeter is just to make them work in aviation. So what happend was air moved away from you making the air less "heavy", that made the needle move. If you look on a weathermap you will see H and L, that means highpressure and lowpressure. Highpressure means you have a high stack of air, and to create balance it flows (wind) towards the lowpressure where there is less air. So that day you where in the highpressure and the airpressure lowerd because of "things needed to be balanced out", this means your altimeter reacted as if you in the airplane going up (lower airpressure). And that is the reason you ALWAYS should check your altimeter before geting in the plane

It is required on every phone but you can turn it off. most of the time E911 GPS cannot be disabled if you turn gps off on your phone there is no `back door` for the police to turn it on, nor (as I said previously) they need it in order to pinpoint your current location. On my phone there is. I can turn on and off the GPS trough interenet, trace it on a map, call it (even if there is no sim-card in it), and lock it from use. I was very suprised when i managed to call the phone when there was no sim-card in the phone. But it works.

I would say Pro mode. If someone rents it that feels confident under canopy they could fire the AAD on the low speed altitude. It happend twice last year when expirienced jumpers used student gear.

Are you sure it was not just the waiter asking you for a refill?

Stay with the large docile rafts until you get the expirience. If you have a camera already you might consider buying a drybag instead?

I have done this on an Otter my old DZ used to bring in a few weekends each year. When the plane would leave on Sunday night to return to it's home base, the pilot would take one last load up to 5k or 6k, let us out, and then continue on to fly the 200 miles home. I would climb out to the camera step, and lower the door before I left. While I felt like I was doing the pilot the biggest favor of all time, I was later told that if I didn't shut the door, the pilot would have trimmed the plane for cruise, left the cockpit and walked back to shut the door himself. Seriously? Seriously what? Him closing the door or the pilot doing it? I have tried closing the door on a AN-2 once but i had to give up after a few tries. But our pilot closes the door himself too in the AN-2 if its cold. What could possibly happen? But sadly we dont have a AN-2 anymore

Could you explain why high pullers go third? At my DZ, if I am pulling at let's say 12,000', I am last out. What is the advantage of your order? Thanks I'm assuming Ron means high relative to other freefallers - maybe someone who is demoing a new canopy and wants to pull at 5,000 but is still going to freefall. I agree that someone who is pulling out the door should be out either first or last (I don't see CRW on Ron's list, but I've seen them go either first or last at different DZs). And he completly forgot about all the skysurfers too But such a list does not work. You have to consider the skill of the jumpers. A smal but novice group of FF will probably drift as much as a RW group, if they jump after the skilled FF they will all be in the same area at pulltime.

Buy a carpet that you use only for packing. If you have wood (or any other hard surface) floor it will make packing easier too.

I got the same problem. Those batteries seem to discharge before their expiry date (EP = Expiry Date). I will check the PD/ED next time. I know this thread is old but it may still help. :-) Ha! This is a oldie. I would also guess ED would be expiry date, but they ssaid EP. Anyways a few weeks after this thread died the batteryindicator showed 100%

You can calculate the distance traveld from the Flysight logs.

http://www.decathlon.es/gps-electronica-keymaze-quechua-500-hike-id_MAN_16538_8161772.html I dont really understand what you mean but there is no reason to wear the Flysight on the wrist as it does not have a display and you need long earphones cables. No rason for that. If you are talking about using the thing you linked to as a altimeter? Those numbers look very smal, not saying it cant be done but it looks very impractical to have such a tiny display to tell you the altitude. And what happens if it looses GPS-signal? Will it show 0 or will it freeze?

There are vibrator apps...... Funny you bring that up, i posted about that on facebook this morning. http://market.android.com/details?id=com.goodvibrations.goodvibrationspro&feature=search_result Check out what Adam thought at the user reviews

Rolf Gibbs G might suit your need? I think that this is the best video you will ever find given what you are looking for.

I used to have pictures of that but i deleted them a few weeks ago Here is a video of a different 0.5x lens, cant remember the name of it. But the Raynox lens is more wideangled and has better focus than this one. http://contour.com/stories/05x-wideangle-lens I belive that we came to the conclusion that the Raynox 0.5 was about the same as a 0.3 of the lens in the video. Looking at the video it does not seem like much difference, but with a Raynox there is a big difference.

Thats what i have been saying all the time
