Fish Finder Buyers’ Guide 

To put it in a nutshell, fish finders make fishing a far easier and fulfilling experience provided you’ve got the right device in hand and our list has some of the best models for the purpose. However, in order to zero in on the right one, there are certain guidelines to remember. If a product’s features align with your individual needs, it’s probably time to bring out the wallet!

Power Rating

Fish finders have their power ratings measured in watts; it could either be high or a low rating. Devices with a higher rating offer greater accuracy in readings and also work well in more depth. If you are a frequent deep-water fisher, it’s best to get a fish finder with a high power rating.

Quality of the Transducer

The Transducer is one of the primary prerequisites of an accurate fish finder. By emitting sound waves (Sonar), it detects the presence of fish for easy location. A simple way to find out how well this component works is to read customer reviews as companies are often misleading in their advertisement.


There are three methods of charging the device. A rechargeable battery, disposable ones, or by plugging it into a power source of 12 volts. In most cases, the specifications are clearly written on the device itself.

12-volt fish finders are the most cost-efficient option and also allow for prolonged operation. However, they must be plugged into the boat at all times which limits their portability. Disposable batteries, on the other hand, is a smart choice for the avid fisherperson.

Display Quality

A fishing expedition is only enjoyable if you’re not squinting your eyes at the display every time you need to take a reading. This is why the display quality of the unit is a crucial factor to check.

Many good models have features like color graphs and larger, high-resolution screens. Ensure that the display works fine in harsh sunlight, as that’s a recurrent problem with these devices. Therefore, backlit displays are a good option if you want to avoid that.


Portability, however, is one of the first aspects to check for; otherwise, the whole point of a fish finder is quite lost. A rule of thumb to remember is that compact designs are easier to pack and carry around as opposed to bulkier devices which are limited in their movement.


Some fish finders are big on state-of-the-art technology and can be paired via Wi-Fi to one’s phone and tablet. This is certainly a smart investment as it brings high operational efficiency, although you do have to shell out quite a hefty amount in some cases. But do keep in mind that less fancy models will do the job just as well and that connectivity is by no means an essential feature.

Cone Angle

While examining the Transducer, it helps to ensure that the cone angle of a fish finder is as suitable for your needs. An angle of 60 degrees is preferred if you want to have a wide view of what’s underwater. On the other hand, narrower cones with a 20-degree angle are better tailored to deep-water fishing.

Dual fish finders combine the best of both. With these units, users have the option to choose between wide and narrow angles. But they’re also far more expensive than regular models and may not suit a wide range of budgets.


You’d think this was a no-brainer for a marine device. But surprisingly many fish finders aren’t waterproof. Many LED screens are prone to damage by water, although Transducers have absolute water-resistance. So, we’d recommend buying a product all of whose parts are waterproof even if it means spending a little more than you’d anticipated. It’s definitely a worthwhile investment.

With that, we come to the end of this guide and hope it has been helpful.

However, to bring you just another step closer to the right device for your needs, we’ve rounded up a few of our favorites.

Deeper Smart’s product makes for a premium choice with impressive overall functioning but it comes at a considerable cost. Speaking of prices, Venterior makes a good case for excellence on a budget and offers good value for money.

So, go get yourself that fish finder already! But before that, do leave your comments below on what you think of our suggestions.
