B175-0-M Broadband CHIRP, No CONNECTOR, Depth & Temperature Thru-Hull Tilted

Model: B175-0-M Brand: Airmar

"CHIRP Fishfinders transmit across a wide frequency band instead of using a single frequency. This is also known as “Frequency Modulation” or “Spread-Spectrum” Transmissions. These waveforms are typically of long duration and for example may start at 42 kHz and end at 65 kHz. Energy transmitted into the water can be 10 to 50 times greater than a traditional fishfinder. « less
