Yeah, the Petrel is a pretty good computer. A few months ago a friend of mine took a mild hit, I was monitoring his vitals and I grabbed his computers to see his profile and record the data, of course one of his computers was a Shearwater Petrel, the other computer well I could never figure out, so I didn’t even bother trying. Getting the information from the Petrel was so easy, I was amazed by how easy it was to extract the information. It convinced my next computer will be a Petrel. As for my buddy’s hit, he was diving very conservatively, both his computers had cleared and were set to the highest conservative setting. He had what we call a undeserved hit, I personally think it may have been linked to lack of proper rest, sometimes something so simple can be the root case, I’m sold on the Petrel!
