The animals were conditioned to boat-follow, wear harnesses with radio backpacks, and deploy mouth-carried recovery hardware. An automatic direction-finding radio tracking system, originally developed for studies of wild marine mammals, was adopted and transformed to a system which is practical and reliable for day-to-day use with trained whales in the open ocean. The killer whales dived to maximum depths of 850 feet and 500 feet to deploy practice grabbers. The pilot whale deployed a practice grabber at a depth of 1654 feet and on one occasion apparently made a volunteered dive (without practice grabber) to a depth of 2000 feet. Float-line recovery devices proved ineffectual, leading to the development of a hydrazine lift system, which was fitted to the operational Grabber and is capable of lifting 600 pounds from 1000 feet. The pilot whale aided in the recovery of a dummy Mk 46 torpedo from 500 feet with this device, and during an earlier training session depolyed the hydrazine system on the same target at a 1000-foot depth.
