Humminbird Helix 9 Di GPS Features

Control unit

Much like all the other Helix 9 models, the Humminbird Helix 9 SI GPS has a great processor that offers fast image updates. This means that the fish finder is 25% faster than old Humminbird fish finders.

It has a 9’’ diagonal display with a 16:9 aspect ratio. The pixel resolution here is 800H x 480V. It’s backlit, meaning it’s easy to read regardless of weather conditions. It gives clear and bright images with enough screen surface.

It’s IPX7 waterproof, which means the Helix 9 Di can take water splashes and immersions up to 3ft under water. It’s also dust-tight.

This product also has precise internal GPS chart-plotting, Ethernet capabilities, and built-in ContourXD maps. It comes with Down Imaging and DualBeam Plus sonar.

Its X-Press Menu system has a one-touch selection to many menu options. It allows you to zoom in and out, freeze the frame, mark GPS settings, take snapshots, and many other functions.

GPS & Mapping

Like the other units, the Humminbird Helix 9 comes with internal precision GPS/WAAS receiver. It provides quick looks with 2.5m accuracy. The device allows saving up to 2750 waypoints and 45 routes.

It can save up to 50 tracks which can also be used as routes. You can add waypoints to them if you want to.

Regarding mapping, it’s important to note that the Helix 9 comes with AutoChart Live. This means you can map pretty much any body of fresh and salt water. These charts feature highlight depth, water level offset, and shallow water highlight. The maps are compatible with i-Pilot Link.

This kind of mapping allows you to set your boat on automatic pilot and follow a specific depth contour.

The built-in ContourXD covers more than 3000 US lake maps with depth contours, channels, access points, etc.

Though the details are limited, its mapping features will help a lot.

The Humminbird Helix 9 also comes with an XNT 9 DI T transom transducer that supports its sonar. It’s dedicated to Down Imaging and works at 200/455/800 kHz.

For DualBeam Plus 2D sonar, the fish finder uses two conical beams: 16/455 kHz, and 28/200 kHz. It uses two fan beams for Down Imaging at 455 kHz.

You can use both frequencies simultaneously, viewing them in a blended or split-screen. Plus, it features the Switchfire function in 2D that does all sonar filtering. You’ll notice how this helps to alternate between information

The Humminbird Helix 9 Di GPS fish finder also features Selective Fish ID+, Split-zoom, RTS, Bottom look, Sonar Recording, and Screen Snapshot. However, the Selective Fish ID+ is only available in 2D sonar.

Another sonar function worth mentioning is the Bottom Lock. It graphs the bottom; flattening it, in a way. It can show you bottom-feeding fish and structure. Real Time Sonar gives you the sonar information caught by sonar echo.

Potential Upgrades

There are several possible upgrades you can opt for. If you ever want to up your game, the Helix 9 DI GPS will help you with the many updates available. This Humminbird model can use a 50 kHz transducer. In 2D, you can use the fish finder for higher depths. Replace its transducer with another compatible one via the transducer replacement program.

For maps, the fish finder is compatible with Navionics Gold/HotMaps, Navionics Platinum+, and LakeMaster charts.

Its internal software is also upgradable. The Humminbird Helix 9 is compatible with AIS, Minn Kota, HD Radar, and PowerDrive V2 motors.

Plus, you have the option of wireless control with the AS RC1 Bluetooth remote control. It has seven keys with long and short press functions. The feature allows you to move through menus, change, views, make waypoints, etc.

This function, in particular, is ideal for all people who are looking to save time as it allows you to navigate without actually touching the fish finder. Its big screen gives you a good view from afar, too.
