When I purchased my dive equipment 3 years ago I purchased the Delta 4 regulator, it came with a swivel mounted on the second stage. Just this year I noticed that my first stage is the PX3 without DVT. Was this first stage ever offered by Oceanic on the Delta 4, or do y'all think that the LDS, where I purchased my equipment from, swapped the FDX10 first stage (with DVT) for the lower grade PX3 since I didn't know any better back then? I was just curious to what y'alls thoughts are on this, and would I really be able to tell a difference if I have the FDX10 first stage installed on my setup instead? Should I invest in the FDX10 or leave my setup the way it is? Y'alls thoughts and opinions. Thanks.
