Humminbird Helix 5 SI GPS Features

Down to the meat, the Helix 5 SI comes with several powerful features that will change the way you fish.

Sonar features

The first of these is the Side Imaging Sonar, which gives you a 180o perspective side-to-side of what you have passed. The ultra-thin sonar beam casts out 240 feet to each side, essentially giving you a 480 foot net that fish can’t escape from. You can zoom in for detail, adjust the color to better suit your hunt, and display range lines to find the distance to an object.

Humminbird Down Imaging gives you a crystal clear view of what’s beneath you by sending out an ultra-thin sonar beam, which returns an exact snapshot of what’s under your vessel. You’ll see an exact portrait of fish, obstacles, cover, the floor, and whatever else may be down there. That said, the use for this unit could go way beyond fishing.

The Switchfire Sonar lets you choose what is displayed on screen. Add or remove as much detail as you like. Refine the results to target your desired species. Use Clear mode to sort out everything but targets, such as distracting noise and current, or use Max to see the whole picture, for optimizing the position of your lure, viewing bait schools and more. Just about anything is possible with custom viewing like this.

The Helix 5 SI comes with single beam sonar and DualBeam PLUS. Use the single beam to see a 20o beam at 200 kHz, which presents you with a precision image beneath you. Combine this with the DualBeam PLUS to also get a wider scan of the area with 83 kHz. With the single beam, coverage equals ⅓ of the depth and with the DualBeam PLUS coverage equals the depth.

Precision GPS

The Humminbird Helix 5 also has Precision GPS built in, that gives you an accurate fix to within 2.5 meters. The Helix 5 SI gives you the ability to mark any number of locations, from important destinations like the docks, to your new favorite hotspot. And Waypoint Management lets you keep track of these by sorting them alphabetically, by time saved, or nearest location. You can also tag them with a variety of icons so you can tell them apart. This allows you to find and return to the spot you want to every time.

Split  Screen viewing

One other amazing feature of the Helix 5 SI is the Split Screen. Want to combine all the sonar modes listed above for an even greater edge? With Split Screen, you can! You can view the picture in multiple sonar modes to pick it apart at even greater detail. This is truly defining. The possibilities here are almost endless.
