DFF3D spatial resolution

[Basumal]

First post to this forum. Excellent knowledge base by the way.

Does anyone know what the spatial resolution capabilities are with the DFF3D, i.e. what is the smallest lump (size and height) that can be resolved in the 3D PBG software? Assume DFF3D 165kHz multibeam transducer and satellite compass corrections are being applied. Cheers, Bas.

Basumal,

The DFF3D’s data point resolution is roughly about 4.9 ft (1.5 meters) when using a Furuno Satellite Compass in junction with the DFF3D's Motion Sensor.

As a comparison, the WASSP that is the bigger brother to the DFF3D and is a commercial fishing multibeam system has data point resolution of about 1 ft (30 cm).

Great, thanks for the reply.
