It's all a bit overwhelming, but you can choose the features that you like because each feature has a dollar sign attached. I should open a shop called "Build a Fish Finder".
Active Imaging and a 3-in-1 Transducer are included. You get superior images at deeper depths, plus all the sonar that you can think of. You can view it all simultaneously with the 6-fold splitscreen.
The GPS feature is able to integrate with AutoChart, Live Navionics, and offers 45 routes as well as 2,500 waypoints. These premium upgrades will almost always be more expensive.
Before I get into the details, I want to say that many of these premium features are available for this fish finder. You might want to pull out your calculator and have it handy. If you don't want to spend more on premium features, the bare-bones models are just a basic fish finder.
Humminbird Helix 5 A2 Chirp G2 GPS Combo is an affordable marine GPS unit. It comes with a 9" color TFT display, and 3 programmable buttons. This interface is simple to grasp and understand making it ideal even for novices. Most fish finders can be purchased for less than $100. The guide can provide you with all the information that you require while you fish. It is also useful for plotting sonar technology.
Let's start with the elephant in the room. This fish finder has GPS, it does have mapping, but it doesn’t have a MicroSD card slot. You are left with what comes with your fish finder unit. Garmin doesn't offer any additional mapping.
There are many options when it comes to sonar, GPS and navigation. That's why I believe it is the best option. DualBeam is an excellent feature for anyone looking for side and down imaging. This will give you the best versatility on the sea.
