As of SonaSoft™ Version 2.6, in-water targets can displayed as an overlay on top of Jeppesen's C-Map ENC and Professional+ charts inside FarSounder's user interface software. In order to comply with Jeppesen lisencing requirements, users must install a USB dongle key on every computer which will display the charts. Users must also purchase the chart data either direct from Jeppesen or through a Jeppesen Dealer.

The USB dongle can be purchased as an option for all FarSounder-500 and FarSounder-1000 sonars. Existing customers should contact FarSounder directly for purchasing details.
