Humminbird has a multitude of high-quality and best-selling fish-finders on the market and it can be difficult to choose the one for you. There are a couple of different versions of fish finders in the Humminbird’s HELIX 7 series, but we will be talking about the 409820-1 model in particular.
Design
The HELIX 7’s backlit LED screen is larger than the average finder, which we’re really appreciative of. When using SwitchFire Sonar (which we’ll explain later), the larger size will come in handy because you’ll be splitting the screen.
In our opinion, the HELIX 7 is one of the easier finders to operate because of its size. Sure, you’ll have to make a pretty hefty investment for this finder, but the enlarged screen and simple buttons make it user-friendly regardless of your experience with fish finders.
Abilities
Let’s talk about the three primary sonar features of the HELIX 7 model:
CHIRP Digital Sonar-Perhaps the best type of sonar available to you, CHIRP picks out the details of individual fish and has the power to punch deep underwater. CHRIP returns crystal clear data to you for the best overall imagery.
SwitchFire Sonar-This application determines how you want to read the data returned from the sonar. There are two common display modes but with SwitchFire you will be able to factor in depth, temperature, and water turbulence to help locate and identify the fish.
DualBeam PLUS Sonar-This sonar is actually two beams in one that converge to give you pinpoint accuracy. Use it to identify fish and structures near the bottom over a wider area than the previous two sonar types.
The purpose of three different types of sonar is to give you the best possible odds of getting a catch. Sonar can be disrupted by the conditions in the water as well as metals and dense materials that might be sitting on the bottom. But sonar isn’t the only feature that the HELIX 7 is good for.
Most fish finders nowadays are coming equipped with different assortments of navigation tools. These tools help you find your way to and from hot spots and drop markers on spots you want to return to. The HELIX 7, in particular, lets you store up to 2,750 waypoints and 45 different paths back to those hot spots.
Overall
If you’re seriously considering the HELIX 7, you’re probably aware that it’s going to be a pretty hefty investment. However we think its well worth the price considering the assortment of tools and features you get.
As much as we raved about the HELIX 7, there are a couple things to keep note of going forward. First is the processing power. In order to sustain the operations of three different types of sonar along with the navigation array, the HELIX 7’s processor generates enormous power and as a result, heat. Many of the complaints about the HELIX 7 have been about it becoming almost unbearable to operate because of the combined heat from the processor and the sun. To circumvent this, you should keep the HELIX 7 in a shaded area of your boat and focus on one application at a time.
Heating and electronics are always going to a pain in the neck, but you’ll get your money’s worth with the HELIX 7. For the price, it’s almost unmatched in user-friendliness and sonar abilities.
