Which Fish Finder is Best for Me?

Buying fish finders can often get quite technical very quickly. This guide above helps break down the functions into digestible terms and specifications to help you find out what will work best for you. It is important to keep in mind the kind of water you wish to fish in (i.e. salt, fresh, ice), at what location and environment, as well as your experience level before committing to a pricier fish finder. Remembering that some fish finders are meant to mount permanently, while others focus on portability may make the distinction for you. 

Also take into account the transducers necessary, beam and cone angels, and screen displays as per your preferences. Screen color, resolution, and size can often be a source of frustration or joy on the part of the fisher. Lastly, keep in mind your budget. More expensive gadgets come outfitted with better sonar, Side imaging and Down Imaging as well, with water resistance, Bluetooth capabilities, and multiple frequency settings. 

While these features can be incredibly handy in shallower waters, providing more details, and overall handedness, if not necessary for your expedition, a more novice fish finder may be ideal. At the end of the day, fishing is an opportunity to relax, get away from the hustle and bustle of life, and take some time to enjoy yourself. 

Be sure to look carefully into the pros and cons of each fish finder detailed above to ensure that it fits with the ambience of your fishing expeditions and adventures from day one, using technology to make your life easier without breaking your piggy bank! Below is a compilation about the more technical aspects of each model to help even new users understand the differences between each fish finder model and type as well as navigate the waters.

The Basics: How Will a Fish Finder Really Help Me?

Fish finders are normally small, somewhat-portable devices that use frequency signals to detect location and topography. When frequency waves bounce off of the nearby water, fish, and landscape below, the gadget in your hand will be able to tell you based on the speed and incidence of the returned wave what exactly is below you. While the science of it is fascinating, (I’m sure most physicists will agree), it is not very vital to the purchasing process. However, it is important to note that these frequency waves, depending on the Hertz (high, low, numerical) emitted from the device, will result in different and varying degrees of accuracy. 

More advanced devices will also provide thermal and color imaging as well as build a detailed image of the bottom of the body of water you are on as you map it out. However, it does come with increased cost to be able to put together a topography at faster speeds. There is a maximal speed that the device will no longer be able to produce accurate pictures at.

What Is a Transducer and Why Do I Need One?

A transducer is simply the basis of the frequency emission system in your fishfinder. It allows the sound waves that are returned to your fishfinder to be interpreted on the screen and displayed in a readable manner so that you can interpret it. 

Similar to a microphone and sound absorber, it converts the frequency waves as needed into electrical output. Most of the time, a transducer is simply receiving input. The better your transducer, the higher quality images and detail you will be able to get. To sense fish underneath the surface, a transducer searches for the air bladder that maintains the fish’s buoyancy. When it hits that air bladder, the input received is distinct and your transducer is able to recognize that. 

The frequency at which your transducer operates can change from product to product. The higher the frequency, the better, crisper picture you will be able to get in relatively shallow waters. However, if you are deep lake fishing, a transducer with variable or lower frequency may be better for your needs. Some transducers are available in variable frequencies, lending the product a good degree of adaptability.

The transducer will also determine how portable your device is. They do need to be mounted ideally to allow for the best degree of sensation in the body of water you are fishing in. They are usually mounted either through, inside the hull, or on the transom (back). More portable ones can be cast. Different mounting style s and transducer styles work best for different levels of fishing and different boats/waters as well. 

Depth and Accuracy

Sonar scans are often key to a good fish finder. Shaped conically,  the pulses of high frequency sound sent out expand over greater distances. The area that the sonar will cover is changed by the exact frequency. The wider the cone, the faster and less accurate the scan will be. However, wide scanning capabilities are often preferred until an object depth of approximately 50 feet. Narrower scans help with deeper waters, give slower readings, and are better for finding exact locations. Depending on what you’re looking for, find a good medium between the two by adjusting the conical angle of the device. 

Be aware of surface clutter. When something is too close to the surface of the water, your sonar will not be able to accurately read it simply because the reflected sonar waves are moving too quickly. This “clutter” or “noise” makes it difficult to identify surface level objects, especially fish that are moving by themselves as well. Some of the more advanced systems will be able to switch frequencies higher to minimize the blind spot issue. 

Deep and Side Imaging fish finders help you see what is on the side of your vehicle and what’s below it. These beams are meant to spread out conically at sharp angles that will lend you extreme detail when baiting fish. This increased visibility also helps fishers distinguish between different features around them, between sand, bottom, fish, or plants. 

GPS

Be sure before buying your next fish finder that the tool has an active and well-functioning GPS system. Not only will it help you get home or to shore safely in the event that you are unable to locate your position simply by eye, but it will help you map out less familiar lake beds and territory maps. While GPS does increase the device price, it is a healthy, safe, and sound investment that will pay for itself multiple times over. Further, be aware that having a waterproof quality to your fish finder may be key to making a good investment, as cell phones do not often fare well in water.

Conclusion

Fishfinders are a fisher’s best friend. Modern fish finders have keen abilities to make fishing not a chore, but an enjoyable task that takes the guesswork out of the equation. Keeping an eye out for price versus amenities ratio will serve everyone, from novice to even seasoned fishers well. Fish finders can be used to see what’s on the bottom of your boat, find bait, map out unfamiliar terrain, navigate and adventure freely, and record interesting readings around your body of water of choice. 

Configuration of these fish finders can vary, ranging from the more complex Hawkeye to FishFinders Pro. Depending on your requirements for configuration, type of boat utilized, screen details and readings, the best transducer for you will vary. Understanding the technical aspects behind it are key to utilizing your fish finder in a way that will help you fish at peace and at ease.

Lastly, practice makes perfect. No fish finder is 100% intuitive, although many improvements in the market have been made over the years to help them become user-friendly. Experimenting with positioning, speed, and settings as well as practicing reading the output display will help you optimize your expeditions with a minimal amount of work and frustration.
