I know that the dive equipment manufacturers need to keep introducing new products to stay competetive.......but I don't think the air trim system is a good choice for anyone looking to advance their diving especially if you are thinking of doing some tech stuff some day. You will not find a wing out there with air trim type of bouyancy control and by the time you get to the stage where you want to take more advanced training you will have already developed muscle memory of the air trim rather than the traditional inflator.
