Detailed Description

SonaSoft 3.5

FarSounder is pleased to announce the release of SonaSoft™ version 3.6, a major upgrade to the software which powers the FarSounder-500, FarSounder-1000, and FS-3DT sonars. This upgrade includes a number of improvements to the processing, user interface, and display software.

For more information please see What's New in SonaSoft 3.6. We recommend that all users take advantage of this upgrade opportunity to significantly enhance their FarSounder experience.

We have spent considerable effort improving the user's situational awareness and strongly recommend taking advantage of FarSounder's expanded chart overlay capabilities. The chart overlay feature requires a C-Map eToken USB dongle and chart data license for each user interface computer. Dongles can be purchased directly from FarSounder for $92 USD. FarSounder can also arrange a complimentary 3 month trial license. Full licenses can be purchased directly from C-Map.

Products Affected

  • Current: FarSounder-500 and FarSounder-1000 sonars
  • Legacy: FS-3DT sonars

Computer Requirements

The new features are computationally intensive and stringent computer specifications are required in order to maintain a fast update rate. The recommended computer specifications for our FarSounder-500 and FarSounder-1000 sonars are posted on our web site. Running this software update on lesser powered computers may result in slow update rates.

Legacy FS-3DT sonars are less powerful and the update may be able to run on your existing computer. Please contact FarSounder at for details.
