    Back in the late 90s I knew people who took it on trips as a backup in case their dive computer died.

    I was on a LoB in GBR(1996) and did not have a computer.
    The diving supervisor declared that any diver who did not have a dc would be limited to 18m! Unless the diver could show him the pre-dive plan by using the "Wheel"!!! No problem for me.
    Bought my first dc when I returned home.

    :happywave: Certified as a (poor) college student in 1988. No way a PDC was going to be in my budget constraints. Certified YMCA (learned on US Navy Tables), but purchased a PADI Wheel as my first waterproof tables (only had the paper ones in the back of the New Science textbook) and learned to use them on my own.

    I've never seen anyone else using one in all these years. I still use it for quick checks. I purchased my first PDC in 1994 or thereabouts once I had a real job.

    I have two of them, both provide the same answers, and both are okay per the "dot calibration".

    I've still got one and will pull it out now and then to practice with. I also show it to students. One of the problems with the wheel was the dots on one would not line up with the dots on another. So you'd get some minor differences unless you "calibrated" it.

    Saw one for the first time on a dive boat in Maui; the DM used it between dives.
    Now I own two, both calibrated, and they often give the same result.

    I still have one. I had to learn it for my Divemaster certification.
