The CSH-7 has a 55 or 70 kHz operating frequency with 800 m maximum range. Two user-programmable function keys simplify operation by providing optimum settings of range, tilt angle, pulselength, pulse repetition rates, TVG, etc. as preset by the user.
When connected with appropriate sensors such as GPS, heading sensor, gyro compass and E/S via an optional interface unit, the CSH-7 displays own ship's position, speed, course, heading and water temperature.
The compact display, transceiver and hull units allow for flexible installation on fishing boats that have limited space.
