Adolescent Water Rescue Manikin
Simulaids - Water Rescue Training Manikins, Item details:
These adult and adolescent models are made of durable plastic with rust-resistant skeletons, articulated joints, and optional CPR capabilities. As the manikins fill with water, they will sink up to the neck. To take them to the bottom, add five to ten pounds of weight (not supplied). A brick will do.
