This self-closing sampler uses our patented spring-loaded Pinch-Pin™ that releases when cable slackens. A safety pin replaces the Pinch-Pin™ when not in use to prevent injury. Removable top screens with neoprene flaps allow water to flow through scoops during descent, decreasing the risk of surface disturbance. Economy version has zinc-plated steel arms and stainless-steel scoop. All-stainless version is best for severe conditions.
Crane and winch recommended due to working weight.
• Centre pivot for low bottom disturbance
• Tapered scoop edges for a clean cut
• Heavy hinges; extra weights available
• Hefty 8200 mL scoop volume
• Self-releasing pinch-pin™
