Bottom profiler H4p


H4p - mobile, compact high-performance bottom - parametric profilograph series Hydra™ (on-Board accommodation). Is designed to study the layered structure of the bottom, to find objects in the bulk precipitation at operating depths of up to 200m and ability to penetrate into the soil up to 50m.
The property is on Board a moving carrier (vessel). The work is based on the principles of bottom profiling.

  • narrow directional diagram

  • large depth of penetration into the soil

  • high resolution depth

  • can be synchronized from an external source

  • digital acquisition and processing of signals

  • the possibility of integration of external sensors

  • small dimensions and weight


  • the classification of the type of soil and bottom sediments

  • search and detection of different objects in the sedimentary layer

  • depth measurement

  • engineering and environmental monitoring, preparation and supervision of construction of the HTS

Basic kit contains:

  1. block transfer and acceptance (BPP)

  2. unit antenna (AU) with cable

  3. power cable BPP

  4. Ethernet cable

  5. mounting kit for attaching the AU to the rod

  6. case for transport and storage

  7. CD “Complexes sonar Hydra containing:

    • FOR the basic set - recording program HyScan

    • the user manual

  8. passport.

NOTE. Cable lengths specified in the order. Possible cable lengths given in the specifications.

The minimum set of components for operation:

  • computer (laptop)

  • the navigation receiver (connected to computer)

  • generator (if there is bortset sufficient power, you can use it)

  • mount BA to the ship.

NOTE. The absence by angle sensors can cause significant errors in determining the coordinates when working at great depths.

The expansion kit includes additional subsystems and accessories, which help the user to organize meals, monitoring of results, to adapt the complex to vessels of different type and displacement, etc., the User can purchase additional sub-systems and accessories yourself or include them in the package.
