The closing mechanism is our patented self-releasing Pinch-Pin™ attached to the two closing arms which holds the grab open before it hits the bottom. Upon impact, the tension on the chains is released, which releases the pinch-pin™. The chain pulls the closing arms together to close the scoops when the cable is lifted.
The top of each scoop is covered with 500 μm stainless steel screen for water to flow through during descent. The screen is covered with a neoprene rubber flap to prevent sample washout during retrieval. Operation requires b” cable (61-B14) and winch, not included.
• Lightweight yet large volume
