I've had this audible for about 5o jumps now and so far haven't had any major problems with it. Some minor inconveniences have been
1. If you FUBAR an exit and end up in someones burble the freefall time may register very short, ie 3 seconds, I think that the pressure change in the burble fools the audible into thinking that you have pulled and stops counting freefall, the audible portion however still works correctly at breakoff and pull settings.
2. Do not use this as an audible to rely on if you are doing a high altitude jump out of a pressurized aircraft. I recently did a jump at 18K (not real high) after the aircraft pressurized at 10K, this fooled the unit to read goofy, at 0 ft AGL it still believed that it was at 1100 feet AGL, which incidently was what we were at ASL. However, this same jump goofed up some other audibles (dytters). Be forwarned, realy on you eyes and your visual altimeters if jumping out of a pressurized aircraft.
3. They operating manual (if you can call it that) is woefully lacking in detail, be prepared to figure some stuff out on your own, like maunually setting your base altitude (see point 2)
Other than these minor things so far I really like it, loud enough to be heard, good value for the price. I would reccomend this audible.
