H5ds37 is a dual-frequency side-scan sonar (DSSS)

H5ds37 is a dual-frequency side-scan sonar (DSSS).
It consists of two SSS operating at different frequencies (high and low).

Fields of application:

  • bottom survey observation, identification of relief features;
  • search for objects at the bottom and in the water column;
  • determination of coordinates of objects and depth of occurrence, estimation of dimensions;
  • preparation and support of construction of various hydro-engineering structures (HES) - ports, hydroelectric power plants, dams, bridges, etc;
  • ensuring the safety of navigation;
  • engineering and ecological monitoring.


  • easy to transport and store – all sonar fits in one case;
  • built-in navigation receiver (optional);
  • wide swath of view and high quality images;
  • ability to upgrade and integrate external sensors;
  • wide supply voltage range, low power consumption;
  • external synchronization;
  • compact size and light weight;
  • mobile or fixed accommodation on all types of vessels.

HyScan - the survey and primary data processing program used by SSSE is included in the basic package. You can download the program through the SW download Center.

Additional information: Documentation

The complex is supplied in various configurations. Recommendations on the choice of configuration are described in the specification.

The basic kit contains:

  1. Receiving-transmission unit (RTU)
  2. Antenna unit (AU) with elements of attachment to the rod
  3. Navigation receiver antenna with cable (if there is a built-in navigation receiver)
  4. Power cable of the RTU, spare fuse
  5. Ethernet cable
  6. Disk " Sonar complex Hydra. MD (maintenance documentation) & SW”
  7. SW of the basic kit -HyScan shooting program with data converters (on disk)

NOTICE. Cable lengths are specified when ordering. Possible cable lengths are given in the specification.

The minimal set of components for the functioning of SSS:

  1. Computer with installed SW of the base kit;
  2. Rechargeable battery or power supply (when powered by mains);
  3. Installation kit (mounting elements).

NOTICE. The absence of a set of angle sensors during operation can cause significant errors in determining coordinates when working at great depths.

The expansion kit contains additional subsystems and accessories that help the user to organize powering, monitoring of results, adapt the complex to vessels of different types and tonnage, etc.. The user can purchase additional subsystems and accessories himself or include them in the package.
