The Bongo Paired Plankton Net System, Series 1200 is a sophisticated sampling device that is capable of multiple unit, simultaneous sampling at mid-ocean depths as well as a reliable single unit tow platform for use in shallow water sampling. One of the unique features of the Bongo system is its opening and closing mechanism that allows discrete "known-depth" sampling. The system has no frontal obstructions to frighten, disturb, or damage the catch and is large enough to filter water at the rate of 47.5m3/minute when towing at a speed of two knots.

Because of the Bongo's simple design and rugged construction, the unit is almost maintenance free. The net frames are constructed of 6061-T6 series aluminum with bronze release mechanism, stainless steel flow meter control lever and rollers. Water lubricated Teflon bearing liners are used in the swivel assembly and flowmeter and are maintenance free.

We manufacture the 1200 series Bongo net system in several sizes. The only difference in the models is frame size or hoop diameter, measured in centimeters. When requesting a quotation for a Bongo system, please indicate the diameter and net mesh that you prefer, along with the filtration ratio of the nets. When you purchase a complete Bongo system, all nets, doors and cod ends are rigged and tested prior to shipment to insure proper operation. One Operating and Maintenance Manual is provided with each order.
