<font color='#0000FF'>matty,
the dolphin come's with four dosage jet's, 32% 40% 50% and 60%. obviously with the correct dosage jet chosen, this allow's you to do 40m.
not 22m as you have been led to believe. the unit is sold with a CE mark and is rated for use up to and including 40M. more is possible if you like to tinker with yer kit!
the lung's arn't hard to clean! neither is any other part of the unit.
i can put my unit together just as fast as you can put yer scuba rig together.the only thing i would slag the unit for is.... it dont come with a po2 measuring unit. it is however perfectly safe to fly the unit without one, i do it regularly!!
it's a bomb proof tool and is far cheaper than anything else , on the market, ok! so it's been around a while and has become somewhat dated!!.....so what!! it work's and that's all that count's.
