Page 3: Introduction
The SonarMite Echo Sounder is the result of nearly two years research and development to further extend the boundaries of shallow water hydrographic surveying equipment. The introduction by Ohmex in 1997 of the SonarLite, the worlds first truly portable echo sounder system, has been a hard act to follow and it remains the portable instrument of choice in many survey companies around the world. -
Page 4: Typical Use Of The Equipment
SonarMite v3.0 (c)2009 Lymtech LLC Typical Use of the Equipment The SonarMite Portable Echo Sounder has been designed to provide a portable instrument that provides the facilities of a „professional‟ sounder at the cost and performance of a „fish finder‟ device. It is important to recognize what the differences are between these two types of echo sounder. -
Page 5: Equipment Supplied
SonarMite v3.0 (c)2009 Lymtech LLC Equipment Supplied The SonarMite is supplied as standard with the following list of equipment … SonarMite main processor unit c/w Bluetooth Antenna Universal EU/US/UK internal battery charger „Smart‟ depth transducer c/w 5m cable and embedded processor ... -
Page 6: Installation & Use
SonarMite v3.0 (c)2009 Lymtech LLC INSTALLATION & USE This chapter describes how the SonarMite Portable Echo Sounder would normally be installed and used. There are three typical ways in which the device can be used for hydrographic surveying applications, either as a „Dumb‟ sounder connected via a serial cable/Bluetooth Link to a PC running data logging and display software, or as a „Logging‟... -
Page 7: Internal Battery Charging
SonarMite v3.0 (c)2009 Lymtech LLC warm fresh water and cold salt water is about +/-30m/Second which represents a change of depth of +/-2%, this must be viewed in context with typical depths of the survey, if a typical depth is 10m then the error could be about 20cm. -
Page 8: Reverse Voltage Protection
SonarMite v3.0 (c)2009 Lymtech LLC Reverse Voltage Protection The SonarMite is protected from reverse connection or direct short circuit by an internal 1.0Amp thermal fuse. If the fuse is tripped then the system will need to be disconnected for 1 minute for the fuse to cool down and reset itself. -
Page 9: Depth Transducer
SonarMite v3.0 (c)2009 Lymtech LLC DEPTH TRANSDUCER The SonarMite system uses a „boat‟ shaped transducer in a „knock off‟ fitting for fixing to the transom of a light boat or more commonly in a temporary mounting using a survey detail pole. -
