Humminbird Helix 12 Features
Auto Live Features
Humminbird designed this model with excellent and sophisticated features that are packed with power. People prefer this model, not only for its huge screen and big sir but also its additional features and benefits.
One important criterion is that hummingbird makes the model of fish finders quite simple to make navigation easy.
Mega Side Imaging
Mega imaging includes both mega sides imaging and mega down imaging. G4N variants with Mega imaging give you the best imaging version, and you can easily view 125 feet around your boat. This model comes with 360-degree imaging and gives the clearest reading and updates quickly. New monitoring areas, locating fish around the radius, and getting their photographic results.
This model allows you to view things easily as it is super bright and had 1500 nits. It has 1280 by 800 HD pixel crystal resolution. This helps to remove glare and view at all the angles more accurately.
The display ensures easy viewing of sonar readings at any time of the day. Due to its brightness and crystal-clear resolution, sonar readings can be viewed during the morning, afternoon, or pitch dark night.
One important feature of the Helix 12 model is 360-degree imaging, ensuring clear readings around the vessel. With mega 360 imaging, you can easily monitor fish and other structures under the water and get the photographic outputs that enter and exit the radius.
Dual Spectrum CHIRP Feature
Helix 12 has a dual spectrum chirp feature that offers you three modes to choose from. It may sound that the number of the modes is only two, but there are three, and you can easily choose your mode from the options. If you want to take larger images, then the wide mode is a good option.
This mode casts signals between 140-200 kHz. You can expect the image quality to suffer from the wide radius. You can switch after finding your target to the Narrow mode. This mode casts a signal between 100-240 kHz. Here you can expect a good image quality, but the size may reduce.
Between the normal and wide modes, you can find another mode called full mode, which combines both qualities and mixes the best quality of both the modes. This model casts a signal between 150-220 kHz. Here you get a good quality image and size and is big too.
All the modes of Humminbird have features of side imaging. It has brought a new model, which is an upgrade version of premium MEGA side imaging without the positive signs and the regular side imaging. It is now Mega side imaging +
The feature of this imaging type is that you can see both the right and the left directions simultaneously. The sides of the vessel receive the beams due to this imaging type.
Mega side imaging + is far better than the previous mega side imaging since it uses high frequency compared to other frequencies, which is shorter. It gives 20% clearer views and 60% better distance than the regular or previous side imaging.
You have three options to choose frequencies:
- 800feet with 455 kHz
- 400 feet with Mega
- 250 feet with 800kHz
Mega Down Imaging
Humminbird has come up with a new side imaging called Mega down imaging+

- 200 feet with mega
- 125 feet with 800 kHz
- 400 feet at 566kHz

Hey there, Patrick here. The Guy behind this blog.
My first fishing experience started when I was 11 years old, fishing for breams in my local lake at home.
In the years following, the hobby turned almost into a full-time pursuit, often requiring the travel of the country to discover new fishing grounds. I enjoy catching pike and king salmon the most.
I have started this blog to share my experience and knowledge about fishing and fishing equipment.
I hope you enjoy my blogs. Wish you good reading..
