V-Fin Depressor

The counterweight fin for operating plankton sampling equipment in horizontal towing mode

Inverse vane for horizontal plankton nets. The V-Fin Depressor gives negative lift to the towing rope during horizontal or oblique plankton net operation. This also stabilises the net in the water and allows for good sampling results. It consists of a lead-weighted body and a stainless steel rope with shackle.
