Meg Head - A Question

Moray Brown · 4th February 2007, 21:10

I know what the H stands for (Hud)
also the S (Sensor)

Can anyone tell me what the A stands for? the one that's not used on top of the head, and also is it possible for air to leak from this as my diving partner was sure he saw bubbles escaping from this.

Cheers,

My guess is that the four ports on the current heads are:

P Primary
S Secondary
H HUD
A Auxiliary

The standard Meg would have the P, S, and H ports occupied by the APECS electronics. I think the idea was that could use the A for a fourth sensor, but I think they have a 4th sensor available in the counterlung now. I haven't seen it yet. I had a 4th sensor in my head for a while, but it's hard to find a good place for it.

On a COPIS, just the primary has been used. I've heard they're working on a HUD.

They've also changed the threading on the head to an o-ring sealed straight thread part.

there is always a possiblity that you could have a leak but it is un likely. the plug has an o ring seal and it is also is sealed with silicon on the threads. so the chance of a leak from here is low.
