USGS Handline w/10ft Rubber Cable & 40ft Ellsworth Cable

A handline is used to make discharge measurements or to collect water quality or sediment samples where it is inconvenient to use a sounding reel or a crane. It does not have a counter to measure water depth, and only 15 or 30-pound (7 or 14 kg) sounding weights should be used with it. The handline consists of a Lee-Au handline reel, 40 feet (12.2 m.) of 0.10-inch (0.25 cm) Ellsworth cable, a pressed sleeve connector, and a 10 foot (3 m), 16-gauge/2-conductor, rubber-covered electrical cord with adapter to complete the electrical circuit from the meter to the headphone, counter or beeper. Additional electrical cord lengths can be specified as required, 65 feet maximum.
