Description

Overview

The SonarMite MILspec system represents the ultimate in portable ruggedised hydrographic surveying equipment, based around the integration of sub-meter handheld GPS with the Ohmex ‘SonarMite’ portable DSP echo sounder. The system, manufactured in the USA, further extends the boundaries of shallow water hydrographic surveying equipment.The release of the MILspec echo sounder marks a further milestone in the introduction of equipment designed around the WinSTRUMENT concept using the latest portable computers integrated with new measurement technologies.

The MILspec SonarMite makes use of a metal case with MIL spec connectors to provide a ruggedised enclosure. The use of Bluetooth wireless technology enables the SonarMite instrument to be waterproof and used in a hostile environment while the more sensitive computer features can be located in a more user friendly environment up to 50m away from the instrument. The SonarMite instrument uses ‘Smart’ integrated echo sounder transducer technology, in addition to highly reliable bottom tracking algorithms using DSP techniques the system also outputs a quality value associated with every depth measurement made.

  • Velcro Wrapped for easy installation

SonarMite Measurements

The SonarMite instrument uses the same ‘Smart’ integrated transducer technology used in the SonarLite system, in addition to highly reliable bottom tracking algorithms using DSP techniques the system also outputs a quality value associated with every depth measurement made. The popular SonarW10 software has been updated to Windows 7,8, 10 versions, in addition to the standard post-processing and editing features found in the SonarLite software the program now includes extended features to implement the additional measurements produced by the SonarMite. Software for the ‘front end’ of the SonarMite is available to run on a wide range of devices from Pocket PCs through to the full range of desktop systems running the Windows operating system.

Active Transducer Technology

The SonarLite uses active transducer technology manufactured exclusively for use with the Ohmex Instruments range of survey quality equipment. All the signal generation, data processing and filtering is performed digitally within the transducer element, thus overcoming problems associated with old analogue technology.

The Active Transducers are available in the standard ‘Boat’ shape transducer using a ‘Knock-off’ body design patented by Airmar, this allows a transducer shoe to be mounted on the rear transom of a boat alongside outboard motors, the active transducer tracking and filtering algorithms are not effected by the acoustic noise generated by the motor. The Airmar patent design allows the transducer to kick its mounting if grounded and thus avoid serious damage.

New P66 Transducer

The standard SonarLite ‘Smart’ transducer has been updated using the new Airmar P66 shell and ceramic element. This design offers an improved ‘slipstream’ design together with a simple ‘clip-on’ fixing clamp enabling easier transducer mounting/removal. The active processor has been updated to a flash memory processor which enables the later reprogramming of the transducer to incorporate new firmware features as they arrive. The SonarLite active transducer is a specially designed Ohmex transducer with firmware designed for survey applications to IMO standards, IT IS NOT THE SAME TRANSDUCER AS THE AIRMAR SMART NMEA DEVICE although it uses the same shell.
