  1. Hi First of all, thank you for all the comments on the subject. The updated pictures were not on the website yet because we haven't got a hold of the model yet and couldn't make any pictures. Although in hindsight it would be better to just post the renders though. The pictures 1,2,3 in the attachment are the updated design with the mount reaching over the bottom of the gopro camera and has much less of a gap between the mount and the camera. I would like to say a little about our thought process here to explain some of the design features. Firsty I think that nothing is 100% snag proof. You can minimise the event of a snaged line to a point, but in the end the lines or the bridle could wrap around in some weird way and not come loose. So a cutaway system on a camera mount is very so beneficial. Secondly the pins are designed to break at a force of about 80 pounds. This is made for two reasons. First: in the event of an full opening of your parachute and still snaging a line on the camera the force on your neck would be tremendous and i don't think that you could be quick enough to cutaway in that scenario. Second: The force needed to pull away grows exponentially in regard to the force that is pulling on the mount. There is always going to be a point were the force will just be to big to pull. The 3-ring system sorts with this on your parachute cutaway and decreases the tension about 200 times. We have tested this a lot and i believe that the best way to avoid it is to break away the whole thing. (in that case you would cutaway anyway) I don't think that any other mounts have that considered. Thirdly is the shape of the mount, on which most of the comments were addressed. And i agree this could have been done better. So i've tried updating it to make it more snag resistant. See attached pictures 4, 5, 6 and 7. The camera is attached as low as possible and the gap between the camera and the mount is as small as possible. The whole footprint at the base is wider than the camera and it curves inward to match the footprint of the camera. The front and back are left partially open to ensure that the tilt of the camera is still possible. Although I think there is really little possibility of a line snaging there. Please feel free to comment. As for the comment from the.legend. I think that Pobrause cleared that up and I would maybe just add that same helmets in skydiving make me feel a bit scared. When you compare them to a motorcycle helmet it feels like a plastic bag around your head. Now I know that the purpose of the two is very different, but most of the helmets i've seen even have a disclamer that state the helmet will not protect you against injury or death. I presume this is so they avoid certification? All in all the two small holes won't affect the integrity of the helmet that much.
  2. I think that most people pass surveys as they just don't want to answer surveys. it's hard to say if only the people who don't think about camera safety pass the survey. I certanly hope that is not the case. Including the possibility that a stock mount will break when it needs to is not the best idea, as a bolted stock gopro mount will withstand a static force of 80kg+. So you would literaly hang yourself before it breaks. As for the cut-away helmet. it is a solution, but certanly not the best one. Some helmets are hard to get off your head and well if you cut away you destroy a perfectly good 300$ or more helmet. Not to mention that you're without protection when landing.
  3. First of all, thank you for your feedback. -The mount would be compatible with pretty much all helmets. -I see the problem with the cookie roller mount, as it for the price does not have a cut-away, as no mount is 100% snag free, and also not suitable for all helmets. -the survey is foremost to see how much camera safety is important to people
  4. Hello, We are designing a new type of safety mechanisem and would appreciate your feedback. on the link below there is survey regarding the use of a safety mechanisem with a GoPro camera among skydivers. The survey is short and wont take more than 3 minutes of your time. Thank you for your cooperation. Greetings, Aleš Jurjec, Matevž Štern https://www.1ka.si/a/103449 If you have any questions please feel free to ask.
