Finally got to try mine out over this past weekend and I love it! Did a couple fairly deep dives (around 120) on the "new and improved" USS Spiegal Grove and it worked superbly. Did the first dive set on the second level of conservatism, then backed it off to the default setting. The alarms are a bit hard to hear like a lot have noticed. I also dive with an old Citizen Aqualand as backup and it was way louder, but when I was listening for the alarms on the Cobra, they were noticibly different sounding. Nice to know which gizmo is actually beeping at any time. Anyway, it wasn't too conservive for me, after all, my wild and crazy diving days are pretty much over and I have a family to consider. All in all, I like it much better than my old TRAC, which it replaced. By the way, I got mine from Divetank also and have nothing but praise to heap upon them. I spoke at length with Rick (the owner) and as busy as he must have been, he answered all of my questions and we even swapped dive stories fro awhile. It came fully accessorized with the swivel and compass, a UK hardcase, spare protective cover and even a spare battery. All for $599 (oh, and free shipping too!). I had the Aqua Lung $200 rebate that I tried to use at my LDS, but he would only quote me the MSRP, which was like $850 and didn't include the swivel and compass, which would have added $150 to the price. So I think I saved around $200. I do support my LDS (more than one, in fact) with a lot of purchases, tank fills, rentals, and ongoing certifications, but $200 is $200.
