Single Beam Echo Sounders
CEE HydroSystems single beam echo sounders are compact, rugged and waterproof units offering the combination of exceptional sonar performance with maximum convenience. By using the latest modern microprocessors, an echo sounder no longer has to be large and impractical to offer survey-grade accuracy.

Jet Ski Survey Watercraft
Collecting bathymetry near shore, inside or close to the surf zone is a hazardous process. Sometimes it is not possible to collect survey data at all in this environment. The surveyor can wade out a certain distance from the shore with a GPS and range pole; this is a laborious process only suitable for covering small areas and is very time intensive.

PPS Synchronization
PPS or 1PPS means “pulse per second” and a PPS source is just a device which provides a high precision signal each second so that an application can use it to adjust system clock time. GPS and GNSS receivers are a source of a PPS synchronization signal, which is used to precisely time stamp data in hydrographic surveying.

Tide Gauge
Tide gauges provide a critical piece of information for any marine hydrographic survey – periodic tidal elevation data. While a hydrographic survey boat is collecting soundings nearby, the tide gauge continuously records the water level against a pre-defined datum to allow the gradual rise and fall of the sea surface to be incorporated into the bathymetry data.
