Humminbird Helix 5 Sonar G2 – 5" Fish Finder with DualBeam Sonar & SwitchFire Technology

The Helix 5 Sonar G2 is designed for anglers who want solid performance in a small package. Featuring a 5-inch widescreen display, this fish finder provides a clear picture with an 800x480 pixel resolution. Its size makes it ideal for installations in tight spaces – such as small boats, inflatables, or kayaks – without sacrificing visibility. The DualBeam PLUS sonar system uses two cones: a narrow 20° beam (200 kHz) for detailed imaging of bottom and fish directly beneath your boat, and a wide 60° beam (83 kHz) for broader coverage useful for locating fish in a wider area. The combination of both gives you flexibility – you can view both beams side by side or individually on the display.

One of the key features of the Helix 5 Sonar G2 is SwitchFire – a Humminbird technology that allows you to control how sonar returns are displayed. In Max Mode, you'll see every detail (including thermoclines, bubbles, and tiny baitfish), whereas in Clear Mode, some of the noise and clutter is filtered out to focus only on the fish and solid objects. This is especially useful under different conditions – for example, in choppy water or heavy vegetation, where you might prefer a cleaner screen.

The Helix 5 Sonar G2 is very straightforward to operate: the second-generation Helix interface is intuitive, allowing even newcomers to set it up quickly and interpret the data. The menu is in English (and multiple languages), but it uses clear icons and layout. The unit does not have GPS or chartplotting capabilities – its focus is purely on sonar performance – which makes it perfect for situations where navigation features aren’t needed (for instance, on familiar waters or as a supplementary fish finder).

This model comes with a standard XNT-9-20-T transom transducer, which includes a water temperature sensor. Installation is straightforward and all necessary parts are included. Additionally, the Helix 5 Sonar G2 can be converted into a portable unit by purchasing an optional portable kit – handy for ice fishing or if you frequently switch boats. With 500 W RMS output power, this small unit can scan depths of about 500-600 feet, covering the needs of most freshwater fishing scenarios. Thanks to its compact yet durable housing, it’s easy to transport and can handle the rigors of on-water use. The Helix 5 Sonar G2 is an excellent blend of affordability, precision, and convenience for any fishing enthusiast.
