Reg identification

[solentdiver]

Can anybody identify the reg in the attatchment? It appears to be a US Divers first stage, but I don't recognise the second stage. The badge on the purge reads 'Tech Dive' and underneath 'Sea' (as does the knob on the yoke). I know the reg is suitable for O2 mixes over 40%. Who are Tech Dive?

Thanks in advance for your help!!!!!

It looks like an Aqualung reg because it is. It is an O2 clean variant of their Cousteau first stage with a SEA second stage with a distinctive green purge button and graphics designed to appeal to the tech diving crowd.

Last year they were cataloging an 02 clean version of their Calypso reg as the "Calypso 02", with the green letters "Oxygen" on the white purge button and a green yoke knob. That particular reg was advertised as being 100% O2 compatible.
