Search and Recovery
Accidentally dropping an object from the dock, from the boat or even onto the bottom during the dive can happen.
If you have lost something in the water and want to find it, then the PADI Search and Recovery Diver Specialty is for you. There are effective underwater search techniques that increase your chances of success; and more or less suitable means for raising the surface of small, large or really bulky objects. Finding and retrieving items can be a challenge, but it's a fun course.
