Life Support Products LSP Cinch Rescue CollarFEATURES The Cinch Rescue Collar allows a victim to enter the collar from either side. When loaded, the victim's weight releases the connector, allowing the collar to "cinch" around the victim. Used for many years by helicopter crews in swiftwater or bluewater rescues, the Cinch Rescue Collar can also be deployed from land or watercraft. As a flotation device, the Cinch can be used as a life ring buoy with the added capability of gripping the victim.
