Simrad announces new software for NSS evo2, NSO evo2 and GO XSE series displays

Simrad announced a new software update for NSS evo2, NSO evo2, GO5 XSE and GO7 XSE displays, providing sonar enhancements, new Navionics functionality and general software improvements.

The update includes improvements to Time Variable Gain and Auto Gain, Network Dual Sounder, Navionics SonarChart Live, Navionics Dock-to-Dock Autorouting (not available in U.S.) and Navionics Plotter Sync, in addition to NMEA 2000 entertainment enhancements.

TVG functionality has been enhanced to remove clutter at the top of the screen without affecting fish targets near the surface. With this enhancement, TVG reveals fish hidden in the surface clutter rather than filtering all returns near the surface, which at times would reduce the usefulness of the top portion of the water column. That makes a difference for anglers fishing the top half of the water column, allowing them to remove clutter caused by suspended sediment, wave action and other disturbances, without affecting fish targets. The update also simplifies the TVG scale, refining TVG levels down to four options, making it easier to use. Additionally, Auto Gain calculations have been improved to yield better performance across a wider range of transducer installs and vessel speeds.

Network Dual Sonar technology allows users to view and control two independent, live sonar sources — from separate locations on the vessel — on a single display. Eliminating the need for separate displays, or alternating networked sonar sources on a single display, this new feature provides anglers with a picture of underwater activity with control.

SonarChart Live gives anglers the capability to create one-inch (.5m) HD bathymetric maps – in real time — on NSS evo2, NSO evo2 and GO XSE displays. Maps are created by converting sonar returns into detailed contour maps as users navigate. Ideal for anglers fishing a new location, SonarChart Live helps raises awareness of shallow areas and reveals uncharted bottom features. SonarChart Live requires a Navionics mapping card with an active chart updates subscription.

Navionics Dock-to-Dock Autorouting (not available in U.S. territorial waters) creates detailed routes for navigating through narrow passageways and channels. The Navionics algorithm factors in data from nautical charts and SonarChart Live, like chart data, navigation aids and water depth, to display the suggested route. Dock-to-dock Autorouting requires a Navionics card with an active chart updates subscription.

With Navionics Plotter Sync, anglers can download the latest Navionics chart data and transfer waypoints and routes between the Navionics app and a Navionics card via the wireless connectivity of NSS evo2 and GO XSE displays. Additionally, waypoints and routes can be imported from the Navionics card to the waypoints/routes/trails database of NSS evo2, NSO evo2 and GO XSE displays. Plotter Sync requires a subscription to the Navionics app and a Navionics mapping card with an active daily updates subscription.

New software enhancements to NSS evo2, NSO evo2 and GO XSE displays enable them to work directly with all third-party audio equipment that conforms to the NMEA 2000 Marine Entertainment/Audio Protocol, including select equipment from audio partners, JL Audio, Infinity and Polk — with more to come.

“We have always been committed to bringing the latest software enhancements to our current customers,” said Leif Ottosson, Navico CEO and president. “We are confident NSS, NSO and GO XSE users will be excited about the new functionality and feature enhancements included in this software update.”
