Waterproof Ultrasonic Sensor

Product Description

The transducer waterproof ultrasonic sensor is both a sender and receiver. It is placed in the water, or in a medium adjacent to the water, and emits an acoustic signal with a characteristic waveform. This signal passes through the water at a known rate of speed and is reflected off any object with a density different than water. When part of the acoustic signal strikes an object, it is reflected back to the transducer waterproof ultrasonic sensor, which receives it and sends it to the processor.

Model NO.: A-TD500T-4

Use: Ship/Fishing Boat

Waterproof ultrasonic sensor 50/200 KHz transducer A-TD500T-4 worked with OVA Fish Finder & echo sounder. Since the body of a fish is mostly water, the depth finder signals don't bounce directly off their bodies - it is the air in fishes' gills and air bladder that create the target. With dual frequencies, the low frequency can search a wide area of deep water for targets, showing schools of fish as wide patches on the screen. The higher frequency offers more detail of objects directly below the boat, showing better bottom formations, bottom-feeding fish, and schools of baitfish, especially in shallower waters.
