Computer on the left arm?

Can anyone tell me why most rebreathers have the computer wired for the left arm?

I've only ever had it on my right and the shearwater on my JJ is standard on the left, I can swap it over but it isn't as good on the other way due to the battery positioning.

Considering all the OC reasons you have your computer on your right, why have the manufacturers decided to put them on the left? Am I missing something obvious for rebreather use to have it this way?
 
Because that was where the Biomarine CCR-1000 nee Mark-15 primary was worn, and because that was the first commercially "produced in numbers" CCR. All else really followed.

The Beckman Elecrolung preceeded that, but it was not widely distributed and had a short service life.

FYI: A blob of solder on a circuit board is all that reverses a Meg's handset for right side wear. Shearwaters, as you say, can be flipped with a menu choice.

Most people are right handed so mounting the on the left allows right handed operation.

There I was thinking that there'd be a sophisticated reason, typical legacy issues. I'm surprised it hasn't been changed over the last 35 years.
 
Because I dont want to scratch the screen when I reach into a hole with my right hand and pull out a Cray ( lobster)

What would they be?

I've always worn my computer and before that timers/gauges on my left arm, just like my watch. Almost everyone I know does the same, apart from the DIR guys.
 
Very true. The main reason for the DIR guys is because the left arm is the 'working' arm, dumping gas, signalling etc.

The DIR guys use bottom timers too, so having the timer on the right arm allows you to light up the display with your torch on your left arm.

I've swapped my Shearwater on the JJ to be right arm due to the length of my HID torch ballast.
 
I !@#$%^& HATE having the controller on my left arm. Aside from the fact that the damned thing is almost the entire length of my forearm (why???), I can't read it or manipulate it while scootering. If it were on my right, WHERE IT BELONGS, I could....

/rant off/
 
Put mine on the right after two dives. Not only does it make much more sense to me there for scootering etc, I couldn't bear the cable on the same arm as my dry suit dump.
 
if you are ascending and use the deflater of the wing the computer is up and behind your head so wen are you at depth ?
dumping from the lungs is on the right on the JJ so thats ok, ( ore dump trough the nose / mouth)

i have a goodman handle the computer must be at the end of my arm to read it, the end of the torch is in the way.. so the computer and SW on one arm ... not ..
then there is also the compass.... runtime table....backup computer..:brickwall

Dry-suit dump is on the right.

People are mostly right-handed for button pushing.

In the UK we wear our watches on the left.

Lack of originality.

I find it much easier to manipulate the buttons with my right hand...especially when I was diving a Vr3. Just became habit to have it on the left. When I switched from OC to the KISS which had the displays on that side it felt weird to have the computer on the right arm. Now with the external monitoring Predator, it's back on the left where my muscle memory says it belongs.

If your scooter is an SS, buy one of my handles for it and you can drive it with either hand. Problem solved.

If you don't have an SS, disregard this post. :ignore:

The main reason is buoyancy control is on left so it makes sense to not have your depth there too. That way you can adjust your depth and monitor it at the same time ... pretty logical ;)
