Background
There are essentially two “mainstream” options for attaching tanks to a rEvo rebreather:
Traditional
These are the traditional brackets that are “semi-permanent.” You can obviously unscrew the brackets and remove the tanks, but it isn’t quick (or easy) to do that and then get them re-installed, aligned correctly, etc.
By the way, if you use these, you should definitely get a 7mm Nut Driver. It is a TON easier than a screwdriver.
These are useful if you have a static set of tanks that you fill, dive and then remove the tank & bracket to re-fill.
rEvo “Travel”
rEvo developed these and started selling them a couple of years ago and then work well.
As the name indicates, they are great for traveling divers or divers that have multiple tanks at home and switch them in and out.
The Limitation
The “permanent” brackets are rock-solid and tanks stay put and never budge. The travel brackets work great with 2L steel tanks. However, I found that they are a bit too “wobbly” for my liking for the taller 3L steel tank. Having only one attachment point makes them a little too insecure for my liking. I have dived with them quite a bit and never had a problem, but I wasn’t a huge fan.
The Solution
While diving with Mike Hall on a rebreather live aboard trip to the Revillagigedo Islands a few years ago, I noticed that he had tank fixation brackets that had TWO cam bands. It turns out that he had made them himself with the help of a friend who welded a few bits together.
I think Don Six made similar brackets for a while but they don’t appear to be listed on his website anymore. Don posted this in June 2017 to the Rebreatherworld Forum: “Here is what I am doing. You supply the original tank brackets, 8 tri glides, and pay shipping both ways. I will do the fabrication and welding for $40 per set.”
Mike did something similar for mine. I supplied the parts and he had them welded by his buddy and sent them back. I’ve been diving them for 3+ years all over the world and absolutely think they are best tank brackets ever!
In case you want to try to build something similar, here is a list of parts I bought:
- R205A- Tank Fixation – Oxygen Side — Qty 1
- R205B – Tank Fixation – Diluent Side — Qty 1
- AP Diving Off-Board Webbing Camband (100-130mm Cylinders) — Qty 4
- Smooth 2″ Stainless Steel Sliders — Qty 12
Here are a few pictures of them and a picture with them on my unit with 3L steel tanks:
