How to Buy the Best Offshore Fish Finder

With numerous types of fish finders out there, if you are looking to buy one for yourself, there is a high chance that you may get confused between the technicalities.

We understand that the experience can be rather daunting, which is why we have listed down a few main features for you to understand and learn from.

Do go through these if you are a first-time buyer or an angler looking for an upgrade. It will not only help you find the best offshore fish finder, but it will also save you from drilling a hole in your pocket as you would know exactly what is worth paying for.

 Offshore Fish Finder


The most important part of a fish finder is its transducer, without which the fish finder is practically useless. Transducers send and receive sonar waves, which are emitted into the water and bounce off of objects.

Once the transducer picks an object, it sends data to the central unit and displays the information on your screen. This information can help you reel in some great catch.

Also, depending on the type of vessel you are using, the transducer material holds a lot of importance.

Screen Display Resolution and Color

Whether you are a day-time fisher or prefer going at night, having a high-resolution display can help you view your screen in any light.

Black and white screens only have up to 265 shades of gray, white colored screens have a million. If you want to ensure that your data can be seen clearly, then opting for a colored screen is better.

Although there are plenty of devices still being manufactured with black and white screens, if you can fit colored screens in your budget, then go for them.

Power Wattage

Every fish finder has a certain amount of wattage it functions at. If you want a fish finder that redraws fast and has a quick response rate, you should look for a device with high wattage.

Devices that have low power will not work as fast, which, in turn, will delay your catch.

Fish finders convert sonar waves from transducers, which is why devices that have low wattage will perform better in shallow water.

On the other hand, devices with a higher wattage will prove to be more reliable even in deeper water as the waves will be converted much faster.

GPS Functions

For an avid fisher, finding the best fishing spot is a moment of joy. Having a fish finder equipped with adequate GPS functions helps you mark and share your routes, waypoints, and location.

The benefit is not only in finding hot spots, but it also helps find the shortest route to the hotspot.

It avoids sloping edges and underwater hills and helps you reach back to your dock safely during times when the weather gets uncertain.

If you can afford a GPS and a nautical chart, it is suggested to invest money in getting it.
