Is there a "hockey puck" size specification?

[frognog]

I'm looking at making a blueprint for revision two of my wrist-mount double hockey puck computer holder, and while I can obviously measure my own hockey pucks to get data that will work, I was wondering if there is something of an industry standard for hockey puck sizing.

I understand some hockey pucks are significantly thinner than others; that doesn't bother me (although if the spec gave a maximum thickness, that would be nice). Mainly I'm looking for minimum and maximum diameter on the barrel and either the minimum and maximum diameter of the protruding face portion or the minimum and maximum width of the "shoulder" between the barrel and the face.

Is there anyone here from the industry who has engineered either the pucks or consoles or wrist mounts for these pucks, and therefore has seen these details? Or, does anyone else know where this documentation can be found lying around?

The reason I care is I'd like my blueprint (or the actual machined plate) to be as likely to be reusable by other people as possible.

Interesting design.

I was actually thinking of doing something similar by mounting both of my hockey-puck computers in console boot and cutting off the hose protector and making a wrist mount for them on that...

curious question... on your metal frame, did you drill holes in the bottom piece to allow water movement to the back of the computer? (I think the sensors are on the back of the computer, but not 100% sure).

You do need a VERY large wrist to mount TWO hockeypuck instruments on one wrist
Don't you

The majority, if not all, hockey puck computers are manufactured by Pelagic Pressure Systems, which is related to Oceanic (don't know if it's a subsidiary, both owned by a common holding company, or whatever). Calling up tech support at Oceanic may eventually get you to the right guys.

IIRC, the older hockey pucks, such as the Data Plus series were designed to be the same size as standard analog depth gauges. There have been a couple size changes since -- look at the Versa and Veo series. I don't know whether they struck off on their own for sizing of the later hockey puck modules, or whether those also mimic existing analog gauges, but looking at dimensions of various analog depth gauges may help you zero in on the right sizes.

The metal back is a solid piece. But the front and back are maintained at a fixed distance from each other so as to not put crushing pressure on the pucks. I found even a slight pressure would cause improper pressure readings (i.e. on my couch, it would indicate a real depth). So the pucks actually float inside a cage, trapped by the fact their faces protrude through the holes in the top plate, and they cannot rock because the back plate is in the way. They would be free to spin in place except for the rubber strip I added. (In my next planned revision, the rubber strip will be replaced by something easier to install and nearly invisible.)

Water finds its way into the console backs (if they work that way - I'm not 100% on whether both of mine do) past the metal plate, because there's never any kind of seal back there.

It's not that bad. It helps that my arms aren't super short; my mom would have trouble with this thing.

I used to try and put two rubber wrist boots onto my arm. They are bulkier than my present setup because of the space around the rubber, and the fact they never sit right against each other, and they were a pain to put on, the straps would cut off my circulation at the surface but be totally loose at 40 feet, and I'd wrestle with rotating them the right way for best visibility once I was under.

Now the two pucks are super close together, I only have a double bungee to get onto my arm, I can hardly feel it yet it stays secure at depth, and it's easy to orient it however I want.

But, yeah, the pucks aren't tiny! Good thing I had to have an arm there already anyways...
