Basically it is a cheap way of mapping the ground contours. The system is a multi-beam sounder which means it marks the grounds depths using a beam width of 120 degrees port-starboard. Not looking ahead or behind but a wide 'brush' looking and marking depths under the boat and each side, all the time. Being a network sounder it does not come with a traditional display but connects into a Maxsea Timezero plotter or a TZTouch. Think of this as a cheap 'Wassp' system which does not plot hardness. The transducer incorporates the motion sensor, instead of the separate motion sensor used with Wassp. This can be a great device for charter angling boats.
The DFF-3D is an innovative tool for efficient fish location and seabed profile surveying, utilizing new multi beam technology. Highly detailed images are derived from the combination of an advanced signal processing system and an amazingly compact multi beam transducer.
Compatible with NavNet TZtouch/TZtouch2 or Windows OS with TZ Professional software.
