RoxAnn GD – for better bottom discrimination

Sonavision’s RoxAnn uses tried and tested seabed analysis techniques to produce colour-coded 2D and 3D charts in real-time. With this, a skipper can quickly and accurately identify what kind of ground is below him, for example, rock, gravel, sand, silt etc, and build up personal colour coded charts, indicating favourable types of seabed most likely to yield his target species.
