Tunnel saturation

Don't get me wrong - I fully realize that for those who can afford it the tunnel is a great tool. I just think for people like me, who skydive on a budget, that you get more bang for your buck doing the "real thing."



Depends on what you consider "Bang".


From this :http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=1314150#1314150

Seems like several think a tunnel session is a good idea.

As for students peep this from that thread:
Quote

My parents video'ed my session in the tunnel with Ron over Halloween. "Captain Smartass" was geeking the camera while he was explaining things to me before we even got in the tunnel!

Seriously though the tunnel was the best thing I could have done at this point in my training, and Ron was awesome. I wasn't even in the tunnel for fifteen seconds before he had already corrected my body position that had been causing unintentional turns. As a student who had been unable to correct these turns since getting off of static line and onto freefall, this gave me such a good feeling. I was unable to jump this weekend so have only had one jump since getting back from the tunnel, but that jump was flawless in terms of the skills I had worked on in the tunnel.

Further, Ron gave me a new way to look at learning these skills and training in skydiving in general. He said that if any Olympian althete were to train for the exact amount of time we are able train in the air before going to the Olympics, we'd see some pretty poor performances. I was getting discouraged because I was doing these bad unintentional turns for eight jumps, but when I look back at my logbook that was only three and a half minutes to practice - I'm not even warmed up yet! Spending fifteen minutes in the tunnel with someone right there correcting things was a tremendous help, and gave me the solid foundation I need to continue learning. I'm sure I would have gotten it eventually, but this way I'm confident because I know I can do it, and I know what was causing the problem and know how to fix it.

Actually I'm feeling kind of funny...I think can feel a tunnel addiction coming on! I wonder what I can sell to make it to the camp in February... And in Feb I won't be able to feign student status, so I'm sure Ron will make me really work this time! (Ha! I was so friggin sore this last time!)

Thanks Captain Smartass!



I can take a student with problems and fix them in seconds in the tunnel.

I can take a person and teach them *much* faster than in freefall. I can pull them out, talk to them and put them back in 10 seconds. In freefall we have to land and get into another plane. Thats 15 min at best.

Quote

The other thing is, all the tunnel time in the world won't help you launch exits and track - two very important parts of any group skydive.



Very true, and it will not teach deployment mals, or canopy ride and landing.

However if I can make it so that the freefall was a piece of cake, I can focus on the other things more.

Quote

I've only ever been in an outdoor tunnel, and yeah it was a friggin blast!!!

>How many solar panels and how much area would it take to generate 750 kw?

About 3 million, around 1.5 million after state buybacks. Area is about 50,000 sq ft, or a square 220 feet on a side. In the case of Perris, that would likely be implemented as parking lot shade structures.

The opposite is true, actually. You downsize the array to meet the _average_ (not the peak) consumption of the tunnel. The utility is fine with people using power; on peak days they just can't handle massive constant loads. A net-metering installation where the array generates 2400 kwhrs a day, and the tunnel _takes_ 2400 kwhrs a day, doesn't unduly load the utility. That's around a 240 kw array.

Yes.
Houston is the location for the first multi-level VWT, with two completely different flight areas operating with the same column of air.
The sale is complete and the site is being prepped.. It is owned by Adren-L-N, who currently have the portable in the U.S. with wall to wall air.

So not looking, at this point, IS building. It will be part of an entire complex including competition class climbing walls, yoga, etc. Full body fitness.. one section of the air will be enclosed and the other open, to suit all preferences.

Yippee!!!:)

What specifically do you mean by "profit margin"? Is that Gross Margin, Earnings Before Tax, Net Income?

Given what little I know about the costs of running a tunnel I presume it is Gross margin which means there are still very large additional costs such as interest, SG&A, etc. that will bring that number down substantially. Or are you telling me that is ETB, or NI? In which case it is a printing press.

If "bang" = swoops, then no shit.

If it's freefall skills, then air time matters. And last year with sharing, I paid for 2 hours of time but got over 4 hours tunnel time (over 2 days). How many jumps to get 5 hours of FF time?

It was a lot of sharing and sometimes over half the session time (some sessions were 4 of every 6 minutes during the hour - I don't recommend that for any extended periods).

If you can do all 4-way in the tunnel, then it's $630 split among 4 teammates ($160 per person or so) for an hour of airtime. For an airplane, it's 60 jumps at one minute per jump x $20 per jump x 1.25 (need a cameraman for the same education so each person picks up a quarter of their lift ticket, I won't add in his packing adder or fee if any - I'll also not add jumps for unused time for exiting and tracking, etc.) = $1500

I'd think $160 was less than $1500, but I'm not on a terribly tight budget right now to understand how spending an extra $1340 is actually more cost effective in any type of freefall training......

So if you're on a budget and want freefall skills, you do get bang for the buck in the tunnel. no comparison.

So I don't really get your quote here, " I fully realize that for those who can afford it the tunnel is a great tool". Your talking about a preference, not monetary efficiency, so the only argument you can bring here is you prefer real jumps. I respect that, but a rationalization based on a tight budget is just plain wrong.

First of all, hardly anybody actually does 4-way in a tunnel, especially the 12 foot variety. There's just not enough room for any but the most compressed formations. 4-way teams that do tunnel camps spend most of the time doing 2-ways. And yes I realize that 2-ways are excellent for building 4-way skills, but they're still not 4-ways. So there goes the $160 per hour deal, not to mention you're not learning about exits, hill-flying, subterminal air, or any other components of what you have called "freefall skills."

Also to consider is the fact that for many of us tunnel time equals airfare and hotel accommodation rather than driving to our local DZ and sleeping in a tent/trailer/bunkhouse. If you're lucky enough to live within driving distance of a tunnel, good for you, but for me travel and accommodation prices have to be factored in.

For me, skydiving equals entertainment. What I mean by bang for your buck is max entertainment for my dollar spent. For $200 I get a full day of entertainment at a DZ. For $200 I get (at best) and hour at a tunnel. So I think my tight budget rationalization holds up just fine.

I've read your opinions on tunnels in a few threads, so telling me to chill is a pot and kettle thing. Stay light yourself.

Go ahead and run the numbers for 2-ways if you like to still consider it against $$$. We do a lot of 2,3,4 ways for camps when we can get them. So basing financial comparisons on 2-ways is fine.

Like I said - if it's what you prefer, then it's what you prefer. Nothing wrong with that. Also nothing wrong with using the tool. So I respect your last paragraph position and would expect the same in return.

>We do a lot of 2,3,4 ways for camps when we can get them.

I have done the same, but I also agree with Canuck that 4-way in a tunnel is not anything like 4-way in the air. I find myself getting good at very odd manuevers in the tunnel - turning in place and practically booty-flying to get enough clearance from the wall, getting big whenever I'm going to pass the 'stall area' by the door, using the bounce that happens whenever we do a point that has a compressed etc. In other words, learning a lot of things that will be useless or detrimental in the air.

4-way in a tunnel is like learning to drive in a 12 foot wide alley. You can certainly learn a lot, but at some point you have to add the other dimension.

I've gotten a LOT more benefit out of 2-way. During a 2-way you can work on one manuever exclusively (i.e. zig/mar positioning) without worrying too much about not having enough room. You can stare at the mirror as you try stuff over and over without worrying about the next point on the 4-way dive pool hung on the wall. Most of the improvement in my 4-way skills in freefall have come as a result of 2-way work in the tunnel (i.e. I used to suck; now I suck less.)

No issues with that.

My issue is the 'bang for the buck' comment. It's always one guy's way and any other stance is wrong. I just crunched the numbers and tossed it out there - it doesn't compare at all.

For me training for 4-way, I get so much more out of one day in the tunnel (time, practice, repetitions) than one day at the DZ. As far as the social stuff, well, it's apples/oranges. We go out and play at night while at a tunnel camp same as at the DZ. (I like exits, I love swoops, I like tracking). A tunnel camp is a vacation for me also, so I have hotel, etc - but I'd rather travel to a tunnel than a DZ, we have DZs here and no one says I couldn't stop at Deland and make a couple jumps anyway during a tunnel camp.

Now for Freeflying, I'm less obsessed and more Type B about it. So I don't see the point in spending money in the tunnel to learn FF. But I really stink at FF. But with FF, I'm all with Canuck's position about B4TB - FF isn't about getting better (for me - and today) it's about goofing around - different kind of fun. I'm much more serious about my learning curve in FS.

So - it's a great tool and extremely cost effective for -what-it-does- compared to trying to learn the same lessons with multiple jumps. That's all, it doesn't have to be the panacea of skydiving, I'm certain last time we checked that it wasn't advertised as such.

FWIW: Unless you are in a parking lot, driving is one dimensional - speed only. Maybe occasionally you turn, but it's really only 1-D. So I see no issue with learning -the mechanics of drivingg - in a 12 foot alley. Maybe more people would learn to stay in their lanes if they did.

OK, now that's funny. It bothers you that it's "always one guy's way and any other stance is wrong" but you end your last post by telling me that I'm "just plain wrong" :S

Have fun in the tunnel, I'll have fun in freefall, we'll both come out of it better and poorer.

Yeah - I see the irony (but I was being specific in terms of $$$ to flying time and math isn't a subjective science - you turned it from $$ to $$ as a function of fun factor - which is subjective).

See you at the soup kitchen.

And yes, I know there is more freefall time in an hour in a tunnel than in 35-40 skydives



This isn't true for us wingsuit flyers! When people make fun of wingsuit flyers I always laugh and tell them I'm getting my money's worth out of the jump :D

In 40 skydives I can get 80 minutes of freefall on average

The problem with tunneltime IMHO, is that it may be a really good 'tool' if you want to get much much better very fast (2hrs airtime in a day) but I started skydiving because I wanted to go skydiving dudes! Getting out in the sunshine, getting in a plane with mates and having a good time is the crack, if it takes me longer to get better doing the real thing so be it!

I think its pretty clear that tunnels cannot depend on skydivers alone to fill their schedules. They will have to build up their customer base by producing programs aimed at certain clientele. Skyventure Colorado has had great success in this area. They are extremely busy with very few skydivers filling their time. Military training programs, both domestic and foreign, are also a viable source. In any business, you cannot put all of your focus on one program. You must be creative.
As far as expense goes, money is a small part of achieving personal best, things like time, commitment, and inspiration to work hard get you where you want to go.
