The ISA500 underwater Altimeter & Echo Sounder provides exceptionally long range measurement capability – in excess of 120 meters.  In addition to providing exceptionally long range capability, the unit has a 1mm accuracy – allowing precision underwater distance measurements to be made.

Altitude & Echo Sounding

The ISA500 utilises sonar technology to derive distance measurement.

Operating by default at 500kHz, the unit utilises a broadband composite transducer and electronics together with an advanced digital acoustic engine.  The combination of these enable the unit to achieve long range and high accuracy.

The unit can be operated at any frequency from 400 to 600kHz – ideal for different applications or operating in conjunction with other acoustic equipment.
