MicronSonar, mechanical sonar - Tritech

The Tritech Micron Sonar has set high standards in compact sonar technology. It is one of the smallest digital CHIRP sonar in the world. CHIRP technology dramatically improves the range resolution compared with conventional sonars and is a feature normally associated with much larger, more expensive systems. The Micron Sonar was developed to be compact, light, inexpensive and easy to install. It is therefore ideal for small to micro ROVs and AUVs. The Micron Sonar incorporates the very latest surface mounted digital electronics and many software features normally found only on full sized commercial systems. Based on experience gained from Tritech’s world class range of SeaKing and SeaPrince sonars, the Micron incorporates the most advanced acoustic features and software available today. The sonar can be controlled by a customer supplied PC or laptop and it can be configured for either RS232 or RS485 protocols. The Micron has an auxiliary port allow it to interface with other Tritech sensors.
