HP hose length for transmitter

[Edward3c]

Why would someone be hoisting your tanks with regular attached? And if there was a chance someone would be messing with my gear I'd be watching it. And them.

Go dive in the Caribbean or SE Asia (Thailand) and you’ll discover boat staff want to be extra helpful.

Right but why would they have reason to lift your entire rig with regulator attached out of wherever it's positioned on the boat?

I've had many boat crew members and dive guides "Help" me to the dive platform, and as I'm standing up, the first thing they grab is the regulator. They also "Help" me back to my dive station. and as I'm coming up the ladder, the first thing they grab is my regulator. These are the same folks that very "Help"fully give a firm push on my tank to ensure my giant stride entry clears the gunwale. Problem is, I may be doing a Hawaiian Flop, or a James Bond roll.

Instead of limiting yourself to a pre-determined hose length...
Start by figuring where you really want the transmitter to live. What location makes the best home for it. Is there a nice little place where it tucks in nicely? Someplace where it is secure and out of the way. Once you find that home, route your old gauge hose to it. The hose should be too long and pass it. Make sure the house flows nice and takes a good path. Once you are settled on that. Measure how much hose it would take.

Now you have the right length hose for your needs. Not some random hose length that worked for someone else.

I use a 6” rubber hose facing off to the right- same side as my computer. One thing about that 6” hose is that it becomes a lot more rigid once it’s pressurized; so, it sticks straight out and won’t move around and smack you in the head. I could see needing a longer hose and a way to secure it if I was routing it left from my right-side HP port. But for my computer and port on the same side, that 6” hose works great.

In some of the diving I do there is no boat ladder. I doff my gear on the surface and the crew help to haul it into the RIB. Experienced crew know to use the tank valve knob to haul the rig out of the water and not the regulator or hoses. But sometimes the crew are inexperienced or new to the job. And like all accidents, if something happens, the number of miles you have driven before without incident doesn’t matter. I use a short hose for my transmitter, just in case. Maybe it’s unnecessary, but I would rather be cautious. I don’t route the transmitter through D-rings or tie it off to anything.

Doffing tanks in the water and handing them over to crew.

Most RIB diving in the U.K. involves removing kit in water where the cox/crew take it onboard, then you climb in over the tubes. There isn’t the time to ‘look’ for a lifting handle, kit is grabbed by whatever is handy and dragged in.

Carefully consider whether or not you REALLY need the transmitter to be on a hose or not. If there is a HP port you can use that causes the xmitter to point down and prevents it from striking the overhead, or other things then I suggest not using the hose. The hose is simply adding another failure point.

You said most of the diving in the UK is done this way, with the crew hoisting the gear over the side of the inflatable. It would naturally follow that the crews that do this see their fair share of first stage mounted transmitters and don't grab the rig in such a way as to damage it. It's not like divers who regularly splash off of zodiacs are replacing their transmitters on a regular basis.

In fact I can't recall one single incident either witnessed by me personally or having read about, where a first stage mounted transmitter was damaged by a crew person improperly handling it.

It probably happens about as often as oxygen toxicity does to a single tank recreational diver when setting a computer for 1.6. Which is never, from what I've seen and read.

You've misquoted me, I said RIB diving. Which is mainly done in the UK by clubs not commercial operators who tend to operate hard boats (which mainly have lifts). Its your fellow divers who are most likely to 'grab' your kit, not professional crew.

And yes I have seen transmitters damaged. Either the outer case or the base cracked flooding the unit.

I go over my shoulder, and through my chest D-ring (also with a splitter block and a button SPG). I've been using the HP QD fittings Randy (Piranha Manufacturing) sells. Non locking, but I've had no problems. It isn't like your LPI suddenly disconnects, why would a transmitter? I do have a stash of the SP QD fittings from years ago. I use them for my wife's console (Peregrine).
