Drysuit Inflator Arm (Catch) Placement
Ryan-K-Explorer started a conversation recently regarding placement options for a drysuit inflator other than the standard chest configuration. Primarily he wanted to be able to keep his chest free of encumbrances so he could squeeze through low, tight “dry” restrictions between sumps without getting the inflator hung up, digging into his sternum or packing the inflator button with mud and jamming it open.

We came to the conclusion that the best option would be the opposite arm to the Exhaust Valve. This would have the added advantage of keeping the chest area smooth, clean and free of hoses for low restrictions while diving caves or wrecks.
Ryan went all in on the idea and ordered a custom suit from Santi with this valve configuration factory installed as well as another modification to the zip placement.
Having dived with Ryan using his new suit on a number of occasions with this valve configuration I could see it all looked very clean while allowing smooth easy access to the valve.
I decided to re-configure one of my back up suits to try the new configuration.
It certainly feels clean in the water without any hose snagging or need to move hoses out of the way when moving through low areas and the valve is easy to find and actuate. I liked it so much I converted my primary suit to the same arm configuration.
One concern was that it would be difficult to connect the inflator hose one handed. This is not the case, it is actually quite easy to do, left or right handed, provided that the hose is un-pressurised, The diver is also aided by the fact that it is very easy to see what you are doing.
Another consideration was hose routing, but after one or two dives this was easily addressed. Ryan simply added a First Stage elbow to his hose, where as my First Stage configuration needed no adjustment at all.
(The videos here are to show the hose routing in-water and the ease of use.)
While using the system it occurred to me that it may also be of use to those using Chest Mounted CCR or Chest Mounted counterlungs where the chest mounted inflator valve could be hidden or difficult to access.
Australian Drysuit Repairs has in the past moved exhaust valves for those customers who prefer the exhaust valve further back around the arm from the standard open water position. We are now offering the reconfiguration of the chest inflator valve to the “Catch” arm placement for those that may prefer it. As always we are happy to discuss the pros and cons of the “Catch” system and the considerations required to decide whether the right or left arm is preferable. The good thing here is that the inflator and exhaust valve seats are interchangeable (specific to brand -Apeks or Si Tech) so you can try both left or right handed operation relatively easily.
