Single Day Grab
The Single Day Grab comprises two stainless steel bucket sections mounted within a stainless steel frame that ensures the grab is square and level to the seabed when it is deployed. Once lowered and the frame has made contact with the seabed, the latch plates on the buckets unlock and they are released. As the grab is retrieved the bridles connected to the buckets come under tension and the buckets close collecting the sediment sample before the grab is brought back to the surface.
The bucket has hinged stainless steel flaps on the top to allow access to the sediment for sub sampling before the grab is emptied .
Additional ballast can be attached to the bucket in the form of lead weights to improve stability and control in stronger currents as well as improve penetration in more compacted substrates.
A double 0.1m sq grab is also available
