      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

FYI: GoPro vs Beacon Interference

Recommended Posts

Cliff notes from the video below:

 

-A GoPro camera, when on, can interfere with avalanche beacons in search mode, causing false signal readings. This finding could possibly confuse and confound a search for a live burial.

 

-The range of this interference is limited and varies by beacon model, however, it is sufficiently large that a helmet or chest mounted GoPro could interfere with the beacon of the person wearing that camera.

 

-How the GoPro does or doesn't affect the transmit function is unknown.

thanks for sharing. the Mammut Avy blog has a decent article about electronic interference with their Pulse beacons. I think they suggested 40cm was around the range that interference occurred, even with items like a digital camera (go pro).

Maybe its just me ... but the article doesn't really say anything usefull. Does it interfere with sending your signal (ie you're buried and can't do anything) or does it interfere with receiving a signal (ie you're searching and can turn your phone off and relocate your digital camera)?

Also, keep in mind when using a compass, that any electrical device will create a magnetic field (eg. gopro, beacon, Mount Hood Locator, stupid metallic bracelet, etc...). If anyone liked to have GoPro mounted near your chest/beacon, perhaps they could use a bit of metal screen to make a mini Faraday cage (just wiki it) for the camera.

Essentially the latter.

We've revised the older text here in light of the additional recent interest:

... but let me know if anything is still unclear (although updates are usually on only an annual basis).
