Possible but I know the engineers at Castle are always working on improvements. Its a never ending. Along with they have other products to keep updating as well in their boat, heli, and plane line of speedos so it just takes some time.
Most companies do not have the extensive line or products like Castle does thats for sure.
From talking with Joe Ford all the time I can tell you its pretty hectic at Castle with the move and all the new products that they are working on. I wonder if these guys ever get any sleep.
