Vintage Double Hose

After much futile searching, I finally found a current, modern Horse Collar BCD to use with my fabulous Sea Hunt twin tank harness provided by Allan Klauda. BC-002 (marketing name Aquatec) is made by Duton Industries (Taiwan) and appears to be very rugged and high quality. It's a little pricey, I paid $220 plus $35 shipping.

I've got one of those. Build quality is relatively okay - holds a lot of air

Yes, I would also like it to be smaller. However, better than pulling a tube for backup during my long swim off shore beach dives in Lake Superior.
