velvet 0 #1 February 19, 2004 I thought audible altimeters worked on measuring air pressure. How can they get an accurate reading inside a tight enclosed helmet where the air pressure is probably different? This will help me choose a helmet (Midwarp vs.Hurricane) so thanks for the help!

freeflyfree 0 #2 February 19, 2004 well, think where you AAD is located...I hope you don't think that little thingy with the button and the screen is the sensor. the AAD has to work stuffed between the middle of your reserve AND main canopies...

jerry81 10 #3 February 19, 2004 Magic! (That's what air pressure is. It changes magically inside your helmet even if you tighten it down real good.) Quote Share this post Link to post Share on other sites

phoenixlpr 0 #10 February 20, 2004 I used my ProTrack on my goggles. Ive tried in the packet of my JS, but I couldnt hear it :(. I have it in my Z1 helmet now. Quote Share this post Link to post Share on other sites
riggerrob 558 #11 February 20, 2004 I wear my Dytter inside my helmet, motivated by fear that a tandem riser strike will rip it off my helmet. The only advantage to mounting an audible altimeter on the outside of a helmet is ease of adjustment. Para-Sport Italia has the best compromise to this dilemma. PSI cuts a few holes in the helmet shell - near the audible - making it easy to push the buttons on an internal audible altimeter. Quote Share this post Link to post Share on other sites
sdgregory 0 #12 February 20, 2004 I have a Bonehead havok and my neptune goes on the outside. First it is strapped in with elastic badns and then it has a velcro enclosure strap for extra security. Like an inny and an outy at once. Quote Share this post Link to post Share on other sites
