Greetings. A month or so back my special ladyfriend gave me an N3 for my birthday. It had something goofy going on with the USB port on it, and therefore wouldn't charge. I emailed Jenn Bishop regarding the problem, and over the course of about 24 hours we emailed back and forth trying to determine if the problem was the N3 itself or the charger. With that we determined it was the N3 that was broken. She referred me to the RMA request form and within a day or so I had an RMA number. I send the unit back via UPS ground on a Thursday. The next Monday I had an email saying they had received it. The following Thursday I get home from work to a brand new N3 on my doorstep that works flawlessly. I post this as a thank-you to Alti-2 and to Jenn, and to let others know what a pleasure this company was to deal with. I was especially pleased with the fast communication, the heads-up email regarding receipt of the broken N3, and the ultra fast packing and shipping of a new unit. I mean really, the old one left my hands on a Thursday and I had a brand new one the next Thursday. That's excellent. Thank you so much to everyone at Alti-2. You will receive my business for my hopefully very long skydiving career.

Please note my limited experience.. but what I've read/seen/heard so far is that if you get an L&B or altimaster you'll be set in terms of product quality and astonishing customer service, end of story. I had an N3 given to me by my special ladyfriend as a birthday present. The charging mechanism was goofy. Jen at Altimaster was prompt with replies on what to do. I ended up sending it back. They emailed to say it was received today. I'll update on what happens, but there is no doubt in my mind that I'll be taken care of. From what I've read on L&B, their customer service is just as above and beyond.

Yeah a good point was made about the durability of adapting a system like that to jumping a few posts back, and I can understand that. But then again if you can make a digital altimeter skydiver-proof, then I can imagine you can do it with the little box on the dog's collar without too much grief.

I'm not going to search to see if this was mentioned in the other threads, but I'm going to go out on a limb and suggest one of those devices that hunters use to track hunting dogs. That would probably work. And apparently it's cheap enough to use on dime-a-dozen hunting dogs and still be economical.

any possibility this would be for sale to just any old body?

yes. i was waiting for someone to mention the gambler's fallacy.

Damn that's a bummer. Sulfuric acid is a no go with a rig. I'd be careful neutralizing it now and assuming its gonna be straight. I wouldn't jump it, period, without an ok from the manu, as was stated earlier. Best of luck.

I did a literature search on chlorhexidine (active ingredient in your mouthwash) catalyzed degradation of Nylon and found nothing. Looking at the structure of the molecule, I'd say it is unlikely to damage Nylon. However, your subject line says bleach. Bleach, especially if highly concentrated, is bad for Nylon. If your rig has been stewing in bleach in your trunk for who knows how long, that's very bad. If you are seeing evidence of corrosion of the metal grommets (due to the white precipitate being hard to remove,) proceed with serious caution. Get your final answer from your rigger. He knows more about this equipment than I do. I'm just adding my two cents.

This is my first post, and I'm an AFF student with three jumps done. There, my experience is plainly stated, so take this how you will. So far I've been reading a lot of stuff on here and in books to try to absorb all I can. I'm obsessed with skydiving. Thanks for all of the good content on the site. I've learned a lot so far. Maybe it could save my life someday. Or every jump. Seriously, thanks. Anyway, I chime in because I'm a polymer chemist wrapping up a PhD with my main focus being the degradation of Nylon as it applies to the offshore oil and gas industry. That said, when it comes to a Nylon canopy, stay far the hell away from: any sort of alcohol - methanol, isopropyl, ethanol (beer, wine, and spirits) any sort of acid - from vinegar (acetic acid) to sodas (club soda even, think carbonic acid) bases - bleach, for instance Now, elevated temperatures (think closed car in summer,) can accelerate degradative processes when any of the above listed are present. In fact, the main degradation mechanism of a polyamide (generic name which encompasses Nylon) is hydrolysis, meaning the addition of water and subsequent cleavage of an amide bond. This doesn't mean you must not get your canopy wet, but it does mean you should let it dry promptly and don't dare let is sit somewhere hot (car) for an extended period of time when wet. Other than that, solvents that dissolve nylon are relatively rare, and you most likely aren't going to be encountering them in any consumer-oriented product. But if you were wondering, I use meta-cresol and 1,1,1,3,3,3-hexafluoroisopropan-2-ol to dissolve samples for analysis. I can't speak on scotchguard or anything else people may regularly be putting on a canopy, simply because I don't know what chemicals are involved. I merely wrote this to try to give back some information to a community from which I have gleaned so much. AJG
