Great combo for scuba with hoses for BC and dry suit as well.
I just replaced main seal on regulator 2nd stage and tested it to work perfectly. 
Spare Air has filling adapter mounted on the hose. 
Computer turns itself on automatically once you are below 6ft of water. 
In case you need more stuff, I have 2nd stage (with hose) of  Cyklon who needs Inhalation Diaphragm #2577, than DIN to yoke adapter, bunch of scuba accessories.
If you come to pick it up in Las Vegas, I will add led belt in the price. 
New season, so just to make sure, all works I took it to the pool for testing.
