Aquatic safety expert Dr. Tom Griffiths now explains how and why lifeguards have such great difficulty detecting bodies on the bottom of “crystal clear” swimming pools. A must see for all lifeguards, managers, supervisors and parents in water safety. Hundreds of hours of filming in a variety of indoor and outdoor pools were condensed into to a new 10 minute lifeguard training DVD with evidence not found in lifeguard training texts. This training DVD clearly and effectively illustrates the phenomenon of Visual Body Blindness and exemplifies how difficult it is for lifeguards to detect victims once they submerge beneath the surface of the water.

It illustrates and emphasizes how under even the best of water conditions mannequins quickly disappear from sight as soon as the surface becomes disturbed by wind, waves or other swimmers.
