Broadband provides greatly enhanced fish detection making it easier to differentiate between the various fish species, large shoals of fish & the seabed. The result is better-targeted catches & a contribution to conservation of fish stocks.

CVS-FX2 features a dual, triple or quad frequency display with either a horizontal or vertical split. A range of Super Broadband transducers are available which operate on 38kHz to 75kHz, 130kHz to 210kHz & 85kHz to 135kHz.

Frequency can be adjusted in 0.1kHz increments for optimum fish detection, identification & also to avoid interference with echo sounders on other vessels. A 28kHz to 60kHz & 130kHz to 210kHz broadband transducer is also in development.

With Koden’s latest software update the CVS-FX2 & CVS-FX2BB can output both depth and hardness data to the Olex system on every depth transmission for a detailed 3D seabed map.  If the Olex system has the optional HT seabed discrimination module installed then Koden’s hardness data output will be utilized to produce a 3D seabed image with Bottom hardness (Ground discrimination) shown, thus enhancing fishing based on bottom contour and bottom hardness information.
