DSE 5 #52 March 18, 2014 Chuck, I did test it. The photo I was trying to find of the snag point being at the base vs being at the attachment is my helmet/fish scale. I can't find it ATM. The VRB came off comparatively easily when rotated but was damn near impossible with a straight turn. It released before the camera mount broke. That said, I'm sure *you* could manage it. You're highly experienced, likely quite capable in a malfunction situation. But most of the people that need to read and understand this conversation aren't anywhere near as capable nor experienced as you. FWIW, GoPro mounts are a tad more expensive than a dime In my case, the case mount flange itself broke before the snap bracket in the mount broke. YMMV.

All true, although I don't know that my experience would help as much as my adrenaline in a snag scenario. I'm about to install the cookie mount that minimizes the snag hazard so I can get rid of the aftermarket aluminum screw attached mount that is a true death trap. Kind of wonder why no one has made a specialty box of even a helmet that incorporates the Go Pro directly into it.Chuck Akers D-10855 Houston, TX Quote Share this post Link to post Share on other sites

You're certainly right on the camera box. It's tough to justify the cost of R&D selling to such a small market. One might think the guys at Go Pro would work on something that would do the job across many applications. Couldn't agree more on the RSL, bro. My new Curv is RSL equipped. It's the first rig in my 29 years of jumping to have one and I've become an advocate. I also find it interesting that there are holdouts on the RSL thing. The stats clearly demonstrate over and over that history is against them.Chuck Akers D-10855 Houston, TX Quote Share this post Link to post Share on other sites
DcloudZ 0 #56 March 18, 2014 JohnMitchell ***Why not use or have an RSL connected? Because it wasn't cool or considered necessary, because other experienced jumpers didn't use RSL's. Because for old timers, RSL's were something optional, that gear didn't have unless you special ordered it. Because you used to be expected to pull both handles yourself or die, and accepted that. Because you believed you should try to deploy parachutes when stable for the best results. Because you want the choice of either pulling the reserve immediately, or taking a delay to get more stable. Right on the $$$. False pride and over confidence, 2 big killers. I feel most people should use an RSL. I heard one very experienced, very high performance jumper stating all wingsuiters should use RSL's. I was surprised but pleased. There's a lot of dead jumpers that would have been saved by an RSL. Want to be stable when your reserve deploys? Try putting your feet on your butt and arching when you chop. Not many people do. That's a very good point John. Nobody ever taught me that, I read that here on DZ.com. Luckily when I did my first cutaway it was almost instinct and allowed for a perfect on heading opening of the reserve following a spinning line-twist malfunction."Better to have a short life that is full of what you like doing than a long life spent in a miserable way." -Alan Watts Quote Share this post Link to post Share on other sites

Luckily when I did my first cutaway it was almost instinct and allowed for a perfect on heading opening of the reserve following a spinning line-twist malfunction. Quote Never taught to arch after a chop? That's pretty mind boggling. Gotta say, I would really question the quality of training on that one. Trying to maintain or regain stability after cutting away is one of the most basic and important techniques to promote a good reserve deployment. In fact, this is the first I have ever heard of it being omitted from the FJC or ongoing training. I know I'm old school and haven't been part of the student training process in more than a decade, but I would really be surprised if the practice of teaching arching with a chop is being omitted on a wide-scale basis. Of course there's always the SIM. From Section 4 - First Jump Course.... PARTIAL MALFUNCTION Note: On single-operation systems, pulling the reserve ripcord releases the main canopy first before deploying the reserve. Partial malfunction procedures for a single-operation system (SOS) are the same as for a total malfunction. 1. Check altitude. 2. Return to the arch position. 3. Ripcord systems only: Discard the main ripcord. 4. Locate and grasp the cutaway handle. 5. Locate the reserve ripcord handle. 6. Pull the cutaway handle until no lower than 1,000 feet. 7. Pull the reserve ripcord handle immediately after cutting away or by 1,000 feet, regardless of stability, to initiate reserve deployment. 8. Arch and check over the right shoulder for reserve pilot chute deployment. 9. Cut away above 1,000 feet. a. If a malfunction procedure has not resolved the problem by then, deploy the reserve (requires a cutaway with an SOS system). b. In the event of any malfunction and regardless of the planned procedure or equipment, the reserve ripcord must be pulled by no lower than 1,000 feet.

If you find the video suspect (I don't), why not borrow a pull-test scale from a rigger, gather up a few mounts, and see what you can come up with. You can also see my Vimeo channel where there are two bridle entanglements during wingsuit rodeos. In neither case did the camera break off at the mount. If there are "a lot of people that have had theirs knocked off in freefall", how is it that we're not hearing about those people from anyone? Helmet surfaces vary. Mounting skills vary. Air temperature may play a role. VRB that isn't mounted correctly can give way. VRB that is mounted correctly won't give much at all. Are you prepared to gamble on the variables?

I do every jump I make no different than you. I'm not going to debate it with you. I expressed my opinion and you're not going to change it. I bet a person could walk around a DZ and knock them off peoples helmets quite easily if they wanted to. I haven't heard or seen that either. I'll not borrow a riggers scale but suggest you do that yourself and inform us of the results since you're the authority on the matter.

jtiflyer 0 #64 March 20, 2014 tbrownIf you do a lot of CRW (CF) or have cameras on your helmet, I can see a reasonable excuse not to use a RSL / MARD system. As a camera/video flyer for a vast majority of my time in this sport, there is no reason why you don't want a MARD or RSL. My last 2 reserve rides were spinning velos on rigs with skyhooks. Cutaway and reserve opened with no line twists at all. Make no mistake, snag points are a much larger threat than a RSL. Quote Share this post Link to post Share on other sites

On the latter, the statement doesn't even seem to make sense. I'm not sure if those are conflicting statements, complimenting statements, or I simply don't get what you're saying. Please explain.

Zlew 0 #68 March 20, 2014 I think it is important to distinguish the 2 (RSL/MARD) For the vast majority of jumpers, I think a MARD and or RSL is the way to go. Statistically it is pretty well established that having one is better than not having one... After doing lots of research and video review, I choose to fly camera WITH a skyhook on my rig that is capable of having it....and WITHOUT an RSL on my rig that is not MARD compatible. To the snag argument- the way things deploy in spinning malfunctions can be very very different between an RSL (which many times fires the PC/bag/lines etc. close enough to contact the jumper as low as under the arm, and/or around the helmet area), and a MARD which tends to keep everything pretty well clear of your body on breakaway. Jumping camera, and high performance canopies...that's important to me. Also, flying outside video gives me some other considerations (like higher pull altitude) to factor into the that decision making process for me. That is the decision I've made, and it isn't for everyone. I hope to replace my Non-RSL rig in the next year, and the replacement will have a Skyhook.

jtiflyer 0 #71 March 21, 2014 ok to clear things up. I believe MARD and RSL are a good thing for camera flyers, and I jump with a skyhook. I believe a Main tangling up with a helmet is a much greater threat than the risk of a RSL or MARD leading to a reserve entanglement. My last 2 reserve rides were spinning line twists under velocities. I was using vector containers equipped with skyhooks. The cutaway and reserve opening were as planned and line twist free.

My last 2 reserve rides were spinning line twists under velocities. I was using vector containers equipped with skyhooks. The cutaway and reserve opening were as planned and line twist free. I think the point that was being made - is yes a MAIN entanglement is a viable concern with a camera helmet...IF one were to cut away with lines around a camera, having a reserve go into that is really rolling the dice. That's why some who jump cameras elect not to have an RSL or MARD hooked up...Has nothing to do with spinning. ~ If you choke a Smurf, what color does it turn? ~ Quote Share this post Link to post Share on other sites

Which is what didn't make sense to me in your earlier post and still doesn't. The whole point behind leaving a secondary reserve deployment system disconnected while jumping full-size camera gear is that the main can snag the gear during a cutaway, causing a reserve deployment with the main still attached to the jumper. The possibility of a main/reserve entanglement under those circumstances is precisely why camera flyers don't typical use MARD's or RSL's. Either we (myself and the others here who are questioning your comments) don't correctly understand your point, or we do understand you correctly and you don't comprehend the risk we are pointing out. To be fair to you, can you again try to explain in such a way that we can all be clear about your position?

Ok I think we are all considering different scenarios here. My biggest fear is deploying my main, and having it entangle my helmet. I jump a velo loaded at 2.2-2.3. If my canopy isnt symmetrical I am going on a ride quickly. If my helmet is tied up, I know I have to cut the helmet away before cutting away the main. Having your head pinned by entanglement sucks cause I have been through it before (I caused the snag kicking out of line twists on a crossfire and it hooked my ring sight). What I am not concerned with is entangling my main risers or lines with my helmet when I am already experiencing a problem. With my last 2 cutaways I had line twists pretty far down bringing the risers very close to my ears. By simply looking at my feet spinning on the horizon, I bring my chin down towards my chest bringing the helmet clear of the risers. With the centrifugal force building, when you cutaway you launch a decent distance from the main, which clears the risers very quickly. With the reserve being extracted away from you, the odds of the 2" reserve risers or the lines entangling are not something I am concerning myself with.
