MIDAS Surveyor GPS Echosounder

Product code : 1489649428

The MIDAS Surveyor has been designed to offer a low cost solution for small scale hydrographic surveys. The system is supplied with a 210kHz transducer as standard, and uses Valeport's own advanced digital signal processing techniques to ensure high accuracy and reliable bottom tracking. With an integral SBAS enabled DGPS receiver, the MIDAS Surveyor will log position and depth data for over 30 hours, as well as performing on-line correction using external heave and tide data inputs. Options include an additional 33kHz transducer, or high accuracy 16 channel DGPS receiver.

    he MIDAS BathyPack is one of Valeport's premier MIDAS 
    products, using state of the art sensors to generate precision 
    Sound Velocity and Density profiles for highly accurate depth 
    and height data. The simple top-end PC software, BathyLog, 
    also allows all profile data to be used to monitor and correct 
    multiple miniIPS pressure sensors, giving you the complete 
    picture with one integrated sensor suite.
