Fish Finder Buying Guide 3

Fish Finder Features for Fisherman Everywhere

Fish finders come with a variety of options and features. Features include GPS units, Bluetooth and Ethernet connections, down and side imaging and more. Here are some common and uncommon features to improve your fish finder experience.

GPS Units

Buying a GPS unit and fish finder separately is an option, but often the more cost-effective (and improved functionality) avenue is to buy a fish finder/GPS combo unit. These are often referred to as chart plotter/fish finder combo units, these use an on-boat GPS sonar to record and display both the current location as well as the underwater characteristics.

Why do you need both? This combination can track locations of excellent catches, notable subsurface structures and can mark straightforward ways back to shore if deep sea fishing. These combo units are strongly recommended for deep sea fishermen or for those in waters where it can be hard to track water depth and location.

Down and Side Imaging Units

Some fish finders feature both down and side imaging, giving you a clear a view of the marine world as possible. These units tend to have shorter range than individual imaging units, but they are great for viewing anything in a smaller area.

Bluetooth and Ethernet Connectivity

The more advanced fish finders have Bluetooth and Ethernet connectivity. The Built-in Bluetooth enpowers features like wireless software updates from manufacturer apps, displays paired smartphone notifications on the display screen. Some even come with an optional Bluetooth remote that enables control of the finders most-used features. Others feature Ethernet networking capability to build a powerful, professional-grade fishing system by connecting multiple fish finders or add-on technologies. Some have both!

Water- and Weather-Resistance

Not all fish finders are water-or weather-resistant. In the importance of being safe rather than sorry, Thunderbolt Electronics recommends a fish finder rated to be water- and/or weather-resistant.
