John and others
First of all, I am glad to see all the chatter back and fourth about the new Delta System. It is definitely exciting to have something new on the market for people to talk about. Let me assure you we have done months and months of extensive testing on the system including all the required "Essentials" skills, including the rescue skills, to ensure that this new Delta System and specifically the Delta Trim Device works for single tank divers who are looking to take a UTD Essentials class or something similar. UTD has a very active R&D team, that has being using and testing this system and putting it through it paces.
UTD, and all members involved with the development of this product, have tested this Delta System thoroughly and we sincerely put our name and reputation behind it. The Delta Trim Device is truly a phenomenal improvement over the standard back mount single tank wings. There is so much more to this new system than "where the LP hose is." The reality is that this trim device really does put the majority of the lift exactly where you need it as a single tank diver. It absolutely helps give the diver the perfect prone position trim that we are looking for, and without the consequence of excess wing flapping around or taco'ing, which in turn allows air to shift in the cell or worse yet creates excessive drag.
The LP dump on the left side works perfectly, and it dumps air from the air cell in both the vertical and horizontal positions. We tested it descending vertically, which of course we don't want to do, and horizontally and even head down and kicking kicking. It works great and the best of all we don't need a "Bungee" system to do it. It is a clean wing and profile when swimming with it deflated. We also moved the LP elbow off the top center of the wing and back to left side to accommodate deflation while staying in the horizontal flat swimming position - that we learned from our side mount configuration. We found it convenient because now you can dump from the left side without having to reach back behind your body to access the OPV. If you have the light in your left hand you have two choices, either reach back with the light remaining in the left hand - taking the light away from your buddy in front of you OR switching the light to the right hand so the light can stay pointing forward and reaching back with your left hand. In either case the Delta Trim Device makes this process much much easier and hassle free. Now by moving the LP dump to the left rear side that means we could now put the OPV on the right side, finally giving you the ability to have right handed access to dump if for some reason your left hand was occupied such as in a rescue scenario.
When on the surface we found it to lift you well above the water line, as the majority of the lift is below the water line and with no affect of throwing you forward or on your face. It was well balanced and easy to maintain a vertical upright posture while waiting for a boat pickup. And yes you can dump gas fast even when vertical. We tested this scootering, we tested this swimming, standing on our head, upside down, right side up, you name it we did it. The Delta Trim Device really was a great improvement over the traditional single tank wing.
Once again I do thank all for taking the time to see the video blog, look at the images, read the information and if you have any question please feel free to email me at ag@unifiedteamdiving. com
