    Prism topaz idiosyncrasies?

    I'm the proud new owner of Tom's gray wolf with a donut wing topaz. Late on the band wagon I've missed the hayday of stories and preferences regarding this unit.

    What elements of the design did/do you find particularly useful or problematic?

    Hoping to gather some of the lore of it's crowning features and avoid some of the negative points.

    I appreciated the magnificent Chett L. built by Robert Landreth refining the unit.

    Also, have dug through the archives for what the internet has to say but the records are getting scarce.

    However, we all have our own values and quirks so I'd love to hear what made it suited to your diving.

    Regards,
    Cameron

    Ps. Apologies to Tom for the ungraceful naming... perhaps I need a christening.

    Re: Prism topaz idiosyncrasies?

    Did you buy a complete unit or just a wing?

    If you got a complete unit, here's a few things to be aware of.

    Be careful with the scrubber bucket pins, especially when you are removing the scrubber bucket after diving or anytime you are taking the bucket on or off. Be very patient with this procedure or you can snap the pins off.

    Be careful with the secondary, not to accidentally drop it or bang it too hard.

    Be careful when you remove the battery compartment each time you open it. Make sure it's clean and put plenty of silicone before diving.

    Inside the battery compartment there is a calibration pod, maybe buy a back up module. Buy a spare wiring harness.

    Make sure you get familiar with the ADV, you usually have to manually fire this when you are Desending. There are dozens & dozens of people that have this first generation Prism Topaz, and they all have hundreds and hundreds of dives on them. The people that have the most dives on these units never post here on RBW, instead they are diving and not posting, I know many of them and they are still happy with this unit even though it's not the latest and greatest.

    Best regards,

    I'd also add the you may want to reach out to Pete and Shaz, I believe they still support the P1 and should have spares (or at least the tooling to make you some) should you need them.

    It's a fun unit, dive it as often as you can.

    I would be honored to reach out to the creator of the incredible steam machine, I may hang in the shallows a while until I fully appreciate their support!

    Glad to know they are still avaliable.

    I certainly intend to! Maybe even get it into some nice warm waters!

    It is the full breather, and with some thoughtful spare too, including the wiring. I'll be primarily diving in the middle of no where so they'll come in very handy... Expect me on the buy sell page as well if something goes pear shaped. I intend to maintain two units, and they are finally at a price point that's logically possible. (Though Tom's was an exceptional deal for a well maintained rig)

    It does seem often those most underwater are least online. Glad to know there are plenty still floating around at 5m and are well loved.

    I've had my eye on one for a decade and finally made the move.

    Thanks for the heads up on the plastic (derlin?) fragility.

    I'll also keep special eye on avoiding flooding.

    In working on my own analog seconadary I did a tear down of the volt meter on a spare guage. No wonder they deserve a little attention to avoid using them as a mace.

    All the best!

    Hi Cameron,

    I believe that the unit is made from a heavy duty polymer plastic. Some parts are not compatible and interchangeable from one unit to another so be aware of this.

    Robert Landreth is a person you should try to introduce yourself to as he has thousands of hours in fixing modifying and changing many aspects of this unit.

    Best regards,
    Chett. L

    I forgot to mention the name PRISM (Pete Readey(s) Incredible Steam Machine) The original logo they had was hilarious if you can find it. One of Pete's buddies did the drawing.

    Here's a link to a fun video, about 6.5 minutes long:

    I remember in the early/mid 90's when Pete Readey was promoting his unit round the UK there was someone else touting a rival unit at the same time who was claiming PRISM stood for Pete Readey's Instant Suicide Machine.

    20 years later are sales tactics much better?
