J.W. Fisher's DV-2 Dropped Video System

Fisher's most economical underwater camera system designed for boat deployment

The DV-2 dropped video system provides a cost-effective method for underwater search and inspection operations. The system is deployed over the side of the vessel and lowered to the bottom. Targets can be verified and recorded without incurring time consuming check out dives. The camera is capable of both downward and side viewing. Topside the DV-2 connects to a video monitor (see SKU: JWFVRM1) or standard TV. The video can be recorded on any VCR to make a permanent record of that favorite dive site or an inspection job.

JW Fishers DV-2 dropped video system is ideal for checking dive sites before entering the water or performing a variety of underwater searches. Difficult or dangerous dives can be avoided, and underwater objects or search areas can easily be viewed and recorded, all without time consuming check-out dives. The DV-2 can assist law enforcement agencies in their evidence recovery operations and help dive rescue groups with their deep-water search operations, eliminating the need for decompression dives.

The DV-2 system includes a high resolution low light color camera in a rugged corrosion-proof PVC housing, two powerful 1500 lumen lights and a Kevlar reinforced urethane coated 150' (45.75 meters) cable. The standard color camera has a 0.8 LUX 480L rating and a Variofocal camera lens. If the DV-2 is 10' (3 meters) from the bottom an area approximately 10' (3 meters) in diameter is being viewed. The high power lights are mounted on outrigger arms placing them away from the underwater housing to disperse the light pattern over a larger area and eliminating lighting "hot spots". Housing is equipped with leak detector circuitry.

The electrical cables are encased in a hollow core polypropylene rope that protects the cables and provides a strong tow member. Sharp, clear video images are produced by the DV-2's camera, which are sent topside for viewing. The high intensity underwater lights are water-cooled allowing many operations between bulb replacements. The DV-2 was designed for use as a vertical drop camera; however, a second tether line can be attached to front of the housing to lift it for horizontal viewing. The housing can also be carried by a diver to perform inspections or film underwater objects.

Unlike battery powered systems, the DV-2 is powered by 120 volts ac allowing unlimited operating time with the use of a small generator. There are a number of options available for the system including color cameras, cable lengths up to 1,000' (305 meters) and various depth ratings to 1,000' (305 meters). The camera, housing with ballast measures (Dia. x L), 5" x 15" (12.7 cm x 38 cm) and weighs 30lbs (13.6 kg), and the cable is (L x Dia.) 150' x 0.75" (45.7 meters x 1.1 cm) and weighs 22 lbs. (10 kg). The complete system comes with an owner's manual.
