LOST AND FOUND - NOW BRING IT BACK UP!
Students will safely learn to locate and recover objects from underwater. Different search patterns will be instructed and deployed. Once the object is located various rigging techniques will be used to safely bring it to the surface. Students will be required to have their own lift bag of at least 50 lbs lift, and 2 marker buoys. It is suggested that students have completed the Underwater Navigation Specialty prior to this course.
Certification will be issued following student's safe demonstration of search and recovery techniques.
Over 4 dives the students combine the use of a compass underwater and the various ways to locate and recover lost items.
It's Archimedes Principle and Boyles Law.
What makes lift bags work? The great Greek scientist Archimedes
discovered the property: buoyancy. According to Archimedes Principle, "any
body wholly or partially submerged in a fluid is buoyed up by a force equal to
the weight of the fluid displaced. Robert Boyle discovered the relationship of volume and pressure.." Because of these laws of physics, a
liftbag that weighs only 26 lbs. on land can raise an object weighing a ton from the ocean bottom.
Minimum Age 10 years, Jr. Open Water Certificate, or equivalent, open water equipment with
compass, 50 lb lift bag, 10 ft rope and 2 marker buoys. It is suggested to have a pony bottle of 30 cu ft with an air pipe attached to a low-pressure inflator hose of the regulator.
