[Texascavers] Helmet-cam videos - 1010
Here is a new helmet-cam video. Its primary purpose seems to be to show the viewpoint of a caver looking at his foot placement while touring the cave. https://www.youtube.com/watch?v=_1cX_EH9f-o He sets the bar for resolution.1440p seems to be fine for such a cave. However, all the head-movements, and the poor lighting might give a viewer motion-sickness. It did to me. This video should give you an idea how to present your future helmet-cam videos. Walk very slow and turn head very very slow - all around not just in one spot. And have a flood-light instead of a spot-light. I thought the sound of the heavy-breathing and foot-steps was too loud, so I turned it way down. I do not think this type of video recording is going to be a fad, as the price of the helmet-cams is getting lower and lower. I am surprised there is not a gate on this cave. I assume the information below is the same cave: https://en.wikipedia.org/wiki/Pettyjohn_Cave I do not think this video is worthy of an award. Feel free to correct me.

Re: [Texascavers] Helmet & light combo
FWIW, I have recently purchased a customDUO insert to replace the halogen bulb in the headlamp (see details below). This was intended to complement the 14-LED side module in the headlamp. It took about 4 weeks to ship from the UK, and I received it in time to install it on the first evening of the TSA Convention in my Petzl Duo headlamp. Installation was really simple and only required a small screwdriver from my Leatherman tool. Several cavers joined me in walking off into the woods to compare the light output of this insert (cost: about $100) with a Stenlight S7 (cost: about $310 for the standard version, including charger and extra battery; $60 extra for version with premium LEDs) and a Scurion 700 model (cost: about $700, including spare battery and charger). Verdict: customDUO insert compares favorably in light output to the Stenlight S7 on highest setting, and to the Scurion700 on lowest setting. The beam pattern is intermediate between the highly focused Stenlight and the very diffuse low setting of the Scurion. Details about insert: cd701-XPG twins, two Cree XPG LEDs, focussed and full flood. Smooth spot optic. Single mode (700 mA regulated) providing 280 lumens. R4 neutral white LEDs. I have not had the opportunity yet to test this on a caving trip, but will report on my impressions of the insert once I get the chance. More info: http://customduo.co.uk/twinmodules.aspx I prefer the Ecrin Roc helmet, it is really sturdy and easy to clean and decontaminate and dries quickly.

Re: [Texascavers] Helmet
@ Andy Zenker I really like this feedback. In my mind, A stenlight meets its full potential in large open vertical caves. Those are the times I wish I had a stenlight. I have worn both helmets, get the same impression. I feel like the Elios is more convenient in tight crawl spaces, but the Ecrin is a safer and more suitable for vertical. I think I'm going to go with a Ecrin.

Re: [Texascavers] Helmet
I put my sten on both an Ecrin Rock (I use for large and vertical caves) and a Petzl Elios (I use for tight and crawly caves). In both cases, I've used a metal or plastic strap mounted on the helmet to slip the light into with an elastic band to keep it there.

Re: [Texascavers] Helmet
Yup, I second the Ecrin Roc. I've seen people trying out the newer styles of helmets and in the end getting back to Ecrin Rocs. They're very good helmets, and comfortable. - Fofo On 26/04/11 14:13, Andy Gluesenkamp wrote: Ecrin Roc.

Re: [Texascavers] Helmet Cam
I picked up a "Tony Hawk's Helmet Cam" about a year ago with the idea that it was cheap enough to risk breaking it in a cave or dropping it in a pool of water. It has survived a handful of caving trips, including a thorough beating against the sides of Robber Baron cave. Here's one for $25: http://www.compuplus.com/i-Digital-Blue-Tony-Hawk-Helmetcam-1011956~.html?sid=6d9v35b715u3v12 For dropping a wide pit lit by daylight like Devil's Sinkhole, it does a reasonable job: http://www.youtube.com/watch?v=2_8H2ewVOd4 In a cave at a range of 2-3 feet with the 2nd brightest setting selected on a Princeton Apex, it does a reasonable job: http://www.youtube.com/watch?v=7G83DLfvW8Y The video quality is about what you'd expect for a camera in its price range: 320x240, 15fps, heavy compression artifacting, and poor low-light response. For your average stumbling through a cave, the results are mixed from poor to unwatchable, usually because they are too dark, but sometimes because of a weakness inherent in any helmet cam: it's attached to you helmet, which is in turn attached to your head. Our sneaky little brains play a very neat trick on us where in shifting our focus from one point to another, we perceive a smooth and seamless transition. Watching *videos* of the same transition, from almost the same perspective, our brains don't know how to perform this smoothing, and the result is violent and almost nauseating. A helmet-cam operator needs a great deal of focus and discipline to overcome the natural instinct to turn his head at a normal speed for a human, and this is a talent I do not have! Overall, it's a fun toy that can shoot some crappy video that's great for your local grotto's recruitment purposes, if nothing else. ~Alan Blevins On Thu, Jul 17, 2008 at 1:10 PM, Matt Turner wrote: > Yeah we've had a few people bring these on our beginner trips and normally > all you really get is a low quality video of hands and dirt.

Re: [Texascavers] Helmet Cam
Yeah we've had a few people bring these on our beginner trips and normally all you really get is a low quality video of hands and dirt. They only capture well where your head lamp is pointed and only then if it's decently bright. Truthfully though as with most things it probably just takes some tweaking to get the results you want out of it.

[Texascavers] Helmet-cams, etc.
Helmet-cams appear to be getting cheaper and more readily available. http://www.weatherconnection.com/product.asp?itmky=882426&s=froogle http://www.distributorcentral.com/images/products/b8a42537-8e69-4ff2-b557- I am predicting that in less than 10 years, you are going to see at least one caver on your trip wearing a helmet-cam. And in the future, video quality will improve, memory will improve, etc. For example, in stores now is Sony's new memory chip, the M2, ( for their new cell phones ) that is 512 megs and is tiny. http://www.mymemory.co.uk/images/products/1142697997-large.jpg [ the web-site claims they go up to 4 gig ? ] In addition, they will probably discover ways to compress the video better, so that future cavers can make longer mpegs or something similar. ( I believe they have already found a way to make .jpegs smaller and better resolution ). Popular Science is reporting new battery research. Imagine if you could have a helmet that was 2 layers of carbon-fiber and sandwiched between was a layer of some sort of flexible battery material ( see ORB ), sealed between the layers and fully water-proof. http://future.iftf.org/2005/12/yet_more_flexib.html Is this your next caving helmet ? http://www.jeccomposites.com/composites-news/2275/DXL-helmet-wins.html It is not hard to find a carbon-fiber motorcycle helmet.
