In December, Cadden has extended its rental pool with 2 new equipments :
- a deep water multibeam echosounder ELAC 50kHz (3000m),
- a sub-bottom profiler SBP 3000 (50m penetration), a system dedicated for use with the KLEIN 3000 side scan sonar.
Cadden is the only French company able to provide for rental a complete system for deep water bathymetry and acoustic imagery combined to sub-bottom profiling. Two surveys have been already completed with success through our rental offer : the first survey concerns cable laying in Africa, the second one pipeline laying in Polynesia.

Dedicated to large GIS data collection, Trident 3D associates high resolution video, geopositioning and photogrammetry for data collection from a vehicule. One year after its release in France by Cadden, this system developped by the Canadian company Geo3D is still the high level technical solution for large GIS data collection.
The advantages of this innovative solution make it very interesting for French local administrations. For example, the city of Nantes have used Trident 3D downtown, in order to identify and locate road signs, traffic signs, street furnitures… ; the city of Cholet will use Trident 3D, in association with the French Forestry National Agency, to locate trees among the streets.
