Line Pull Signals

Today (Feb 26, 2010) we went to a new dive site to practice line pull signals. The depth at the site was 33' and sea bed was wide and flat which was perfect for running search patterns. The point of this exercise was to familiarize us with the US Navy line pull signals in case of lost electronic communications. As soon as we hit the water we were on line pull signals which is a means of communication between the diver and his tender via pulling on the diver's umbilical. The diver's started the exercise by running a widening arc pattern on the bottom as directed by their tenders. Once the instructors were confident that the diver's were following the line pull signals correctly and making good arcs they started throwing small weights into the water all around the boat for them to find. It was a good exercise and each diver got quite a bit of bottom time to practice the signals. David Jones even got to spook a Blue Herring off of its perch by coming up beneath it at the direction of his tender.
