Periskal Radar Overlay is the best product for navigation on inland waters. The electronic map and radar image are integrated into one image. This gives a perfect picture for navigation. Periskal Radar Overlay is a further development out of the Tresco Inland ECDIS Viewer, navigation software used on more that 3600 inland vessels. The radar image is generated through a Radarbox connected with the PC. This means you can upgrade an existing Tresco Inland ECDIS Viewer with the option Radar Overlay. Every inland river radar can be used. The product is certified by the Rhine Commission.

The Periskal Radar Overlay distinguishes itself by the clear and easy user interface. The systems works as good in Holland - Zeeland, the Rhine, the Danube as in harbour areas. The radar image is stored so you can analyse the image later in case of an accident.

The system is using a double screen, one of it is the radar screen itself. (With modern TFT radars ) On the radar screen you will find the combined image of radar and chart. On the second screen you will find extra information and additional functions. The AIS transponder can also be integrated in the system.
