The Lungfish Gemini Dual Tank Valve is supplied with a mounting block allowing the unit to be mounted vertically or horizontally directly onto your webbing or harness. It connects to standard regulator hoses.
The Lungfish Gemini switch block is a beautiful piece of precision engineering made out of marine grade brass for durability and oxygen ready straight from the factory.
