The MIDAS Surveyor is a revolution in small boat survey work. With an integral GPS receiver and Valeport’s unique “fuzzy logic” digital echo sounding technology, the Surveyor is quick to deploy, rugged and reliable, and boasts many features to make your work as easy as possible. Valeport also offers a range of tide gauge & sound velocity products to compliment the Surveyor - see the separate brochures.

Echo Sounder
Single (210kHz) or dual (210 / 33kHz) channel input, using unique “fuzzy logic” DSP to give accurate readings and reliable performance, even in shallow water. Data may be logged and output either raw (as measured) or corrected for tide and heave.

Position
MIDAS Surveyor logs and displays DGPS position data in WGS84 or Local Grid. User has full control over spheroid and projection constants for Local Grid setup.

Other Inputs
The Surveyor will accept data input from all the additional sensors listed below. All data may be logged and output in real time on a single RS232 channel, and tide & heave data may be used to provide real time corrections to depth data.

Data Outputs
Real Time RS232 output on a single channel of any, some or all of the active data inputs, in choice of industry standard formats.

Memory
16Mb internal FLASH memory provides nominal 32 hours of data logging. An optional 32Mbyte memory is available at time of order. 

Data Display
240 x 128 pixel graphics LCD display, providing numerical and graphical depth display, position data (WGS84 or Local Grid) and all other incoming parameters. On screen help and simple menu-driven setup functions allow full system control.

Software
Surveyor is supplied with SurveyLog, a Windows based software package, allowing data extraction & display. All data is presented in ASCII format, and may easily be exported for use in industry standard hydrographic survey software packages, or simple XYZ format data.
