angrypeppers 1 #1 September 28, 2006 I just started my AFF, and geek that I am, I bought two used altimeters off the classifieds here: an Altimaster II and a Galaxy. I've already sent the II to Alti-2 for a recalibration/checkout, but am curious about what to do with the Galaxy. It's in great shape, and seems to work on the ground (needle moves with weather pressure changes). Not really a comprehensive check, I know. I don't want to use it before I know it's accurate. My question is this: Should I send the Galaxy for a recalibration too, or can I just take it on a few jumps as a backup and check it in the plane against my student altimeter? I'm going to use a student alti for my jumps till I know that the Galaxy is working correctly, or I get the II back from the recalibration, so it's not time critical for me. Thx!

chutem 0 #2 September 28, 2006 You might consider asking one of your instructors to test jump it for you and compare to theirs. Also the school might have crude test/calibrate chamber you could run it through. James Quote Share this post Link to post Share on other sites
bch7773 0 #3 September 28, 2006 ask an instructor to wear it for you on a jump. and why did you buy two visual altimeters?! MB 3528, RB 1182 Quote Share this post Link to post Share on other sites
angrypeppers 1 #4 September 28, 2006 I was waiting for someone to ask that question! I bought the II first, since I liked the idea of the bigger face on it. But then, I found the Galaxy for a *really* nice price, so I bought it too. Figured I could try both and sell the one I liked least. I'll ask an instructor to check it out on my next jump...

councilman24 36 #5 September 30, 2006 Lots of riggers used to have vacuum chambers to test FXC12000's. I have a vacuum dessicator and an electric pump that will get me up to well over 12000'. Hmm, acutally I've never bothered to let it keep pumping. Ask around and see if anybody has a chamber. Jumping it is fine but with a chamber you can watch it more carefully. Or just check the trees from time to time to see how big they are.I'm old for my age. Terry Urban D-8631 FAA DPRE Quote Share this post Link to post Share on other sites
angrypeppers 1 #6 September 30, 2006 Thanks for the info, Terry! I'll bring it up to the DZ next time I jump. I have a feeling the Galaxy will check out just fine, and Alti-2 has already shipped the II; so I should have it Monday or Tuesday.
