Fish Ray Handheld Sonar Depth Sounder Model FR300
Operating Depth: 2’ to 399’.
Simply place the nose end of the Fish Ray in the water and pull the trigger to quickly obtain water depth measurements. Readings instantly appear on the digital LCD display in feet. Once you determine a stable bottom depth, you can then slowly sweep the Fish Ray through the water to scan for sudden depth changes that indicate the presence of fish or contour variations. The rugged, high-impact housing is waterproof and floats.
Global Water Flow Probe Hand-held Flowmeter, 3’ to 6’ Expandable
Ideal for storm run-off studies or flow measurings of rivers, streams, canals, and sewers. Incorporates true velocity averaging for the most accurate measurement possible. The probe shaft is available in lengths that extend from 3’ to 6’ and from 5’ to 15’. Located on the bottom tip is a protected Turbo-Prop sensor which uses the most advanced positive displacement technique available. For minimal friction, this 2” Turbo-Prop sensor rotates freely on a bearing shaft with no mechanical interconnections. Magnetic material in the propeller passes a pickup coil in the housing producing electrical impulses. These electrical impulses are then carried by wire to a readout display on top of the handle. This readout display amplifies and converts the signal into feet/meters per second readings. Instantaneous velocity and true average velocity are then displayed. A unique two-button keypad allows other functions to be displayed including minimum/maximum velocity, time-of-day, timer, totalizer for batch flows, and RPM for accurate low velocity measurement. Features a 30-record memory, padded gun-type carrying case, five-year long life battery for readout display (no battery required for Turbo-Prop), and low battery indicator. Probe can be extended up to 25’ with standard PVC pipe and electrical extension cable.
