How often can the FS-3DT and FS-3ER systems generate a complete picture ahead of the vessel?

Unlike some systems which take up to 90 seconds to complete a large field of view scan ahead of the vessel, the FS-3DT generates a high resolution, full field of view image once every 1-2 seconds. FarSounder technology is able to give the user a near realtime picture ahead of the vessel. Longer range systems such as the new FS-3ER generate a high resolution, full field of view image once every 2 seconds.
