Nothing at all wrong with the Petrel 2. Great computer. Doesn’t have AI, but pretty much has everything else. The SWs seem to hold their value well, so down the road, if you want to move into AI, you can sell that and get a Perdix AI or Teric, or whatever else is in the lineup. Or, just keep the Petrel as a backup.Great input - thanks all for your responses. I’ve purchased a Petrel 2 as my first DC. A bit of an add-on to this - I’m still fairly new to diving and learning a lot everyday - it seems like many dive ops require you to carry a DC.
It really depends. Some shops will also offer a puck style computer in lieu of the depth gauge. A 3 gauge console, without computer, will suffice depending on the op you are diving with. If they require a computer, that won’t suffice, but you have your computer now, so no need to worry about that.All of my dives, with rented or provided gear, have included the big 3-piece: pressure gauge, depth gauge and compass. Does that typically suffice? Is it always provided with rental gear? Anywhere inputs on where it is NOT?
