Product Features


The Humminbird 409590-1 HELIX 5 Fish Finder is a dual frequency transducer that comes with both the 60 and the 20-degree cone. It comes with both the 83kHz and the 200kHz frequencies that make it ideal for both deep and shallow water fishing. This means that the unit can be used by both professionals and newbie anglers. It is an important device for commercial use since it helps to map out the area with the targeted species of fish.

The 200 kHz frequency allows the angler more details and sends in more sonar waves. It is an ideal device for anglers who fish in areas that have weeds and other objects that make it difficult to single out fish. The fact that it comes with a dual frequency transducer allows the anglers to switch between the broader and the general view depending on the circumstances.


The Humminbird 409590-1 HELIX 5 Fish Finder has a peak to peak output of 4000w and RMS output of 500w. This is enough power to allow the unit to provide a good representation of the bottom down accurately. It can give clear images up to 1500’. The wattage is great and allows the unit to display readings almost immediately even when the depth is high.

In fact, this is why the unit is a great asset to anglers who ply their trade in deeper waters.

Nonetheless, the unit can also be used by anglers who fish in shallow waters, thanks to the 200 kHz frequency that allows the unit to display readings in shallow waters. However, the angler will get better results when fishing in deep water.

Screen Resolution:

The Humminbird 409590-1 HELIX 5 Fish Finder falls in the 5 series category that features finders with 256 color TFT display and 800 x 480 pixels. This implies that the screen is capable of displaying 800 dots in the row and 480 dots in its columns. It suggests that the screen is capable of giving the angler more details and sharper and crisper images.

This alone makes investing in this finder a good proposal. When we add this to the great screen that features 5" WVGA display, it makes the investment worthwhile and guarantees your return to your investment. It gives clear pictures of what is happening at the bottom and enables the angler to make an informed decision.

Cone Angles an Beams:

One of the reasons why anglers choose the Humminbird 409590-1 HELIX 5 Fish Finder is that it features a transducer with 20 degrees and 60 degrees cones. This means that the 20-degree cone gives anglers who want to fish in water with different depth a head start.

While the 60-degree cone delivers to anglers a wider area and gives them an upper hand when mapping out the areas they should focus on.

It is a dual beam PLUS sonar that allows for gimbal mounting even though it comes with a temperature gauge built into the transducer.


The unit comes with transducers whose job is to emit and receive signals and waves. It sends signals into the water, which when they collide with the object such as fish, weeds or ridges, they bounce off and get picked send data to the main unit to be translated into pictures and displayed on the screen

. This helps the angler to interpret and understand what is beneath the water and take the necessary action. The unit features a conventional XNT 9 transducer that can be mounted on the smooth side of the boat or a transducer mount.


The Humminbird 409590-1 HELIX 5 Sonar is certainly one of the finders you should buy as a present for your loved ones. It features a 5” WVGA display, a dual beam, and is the right tool you need for searching the shallow and deep water.
