What's the smallest Halcyon DSMB with an OPV

[wilbo]

All,

I am looking for a small 'H' Closed Circuit dsmb with an Over Pressure Valve.

As I understand it - the 3.3' Closed Circuit model does not have an OPV - and therefore does not vent gas as maximum pressure is reached on the way up to the surface. Consequently it bends like a banana on the surface! Question: Is this not a design flaw?

So - who uses the 3.3 Closed circuit version and how do you get on with it? Any problems on the over inflate?

thanks in advance.

I have the 3.3' CC and it has an OPV - just fire and forget

You want the Closed Alert Marker rather than the "Oral" version, it costs £5 more.

I'll have it with me at Plymouth, you can have a butchers.
