Buying Guide

As fish finder technology improves, you have a lot more things to consider before buying. The sonar used in fish finders gives you a better look at what’s in the water, which is at the heart of why you need a fish finder. However, there’s a whole lot more to it these days.

Conventional Fish Finders

A conventional fish finder uses sonar to collect information about what’s going on under the water and then it displays what it finds on a screen. It helps the angler by telling him more about the water and how to find the fish.

These units usually detect depth, temperature, and major structures like plants, sunken boats, and other objects. However, the amount of detail provided will vary significantly based on many factors. One of these would be the best fish finder for kayaks, canoe, or boat.

A basic fish finder will display crude, undetailed images while a high-end fish finder will show what look like photographs as it interprets the information it gathers via sonar. This rich detail can make it so much easier to read, but more complicated to set up or use.

Flashers

Flashers take a more simplistic approach to the information they find beneath the water, displaying the depth of the body of water, the depth of any fish it finds directly below you, and the depth of your lure.

While the information you receive isn’t as detailed as some other modern fish finders, the simplicity is a welcome relief to some of the more complex or overwhelming devices you might find on the market.

Flashers are great for ice anglers and also work well for the outdoorsman who likes deep water vertical jigging. While it’s probably not the best kayak fish finder, some conventional fish finders have a flasher function included, so you have it if you need it.

Flashers are portable, so they’re easy to move with you, which is part of the reason they’re great for ice anglers. You don’t have to mount them to your boat and leave them. You can have it with you as you navigate the frozen surface.

GPS Combos

Many conventional fish finders also feature GPS technology. These are fantastic tools for any angler because they have all of the same features you might need on a fish finder with information about your GPS location.

The best fish finder for a kayak, and indeed the best fish finder for any vessel, is one with GPS, because it adds so much to the experience. You can record exact locations of high fish activity for a return later, you can track your route, and measure your speed.

With advanced information about your location, you can plot charts and use fish finders to help navigate. Most mid-tier fish finders now include GPS capability, so it’s much more accessible than it used to be.

Castable Fish Finders

Castable fish finders are exactly what they sound like. You can attach them to the end of your line and cast them into the water. They use sonar beneath the water to collect information and then send that information back to your handheld display or your smartphone.

These types of fish finders are popular because you don’t have to mount them to anything. If you use your smartphone or tablet, you don’t have an extra piece of equipment taking up room on a boat that’s already small, like a kayak or a canoe. They’re also more affordable than other types of fish finders because they don’t come with the extra equipment. View our top choices for this type here.

Display Screens

Your fish finder can collect more information than any other fish finder on the market, but if it can’t display it in a way that’s easy for you to read or understand, it’s useless. Make sure the fish finder you purchase meets your expectations when it comes to a high-quality display screen.

While some basic models don’t have all of the complicated gizmos, that’s ok, as long as you know what you’re getting. Even a fish finder that transmits to your smartphone is a convenient tool as long as the app on your smartphone gives you the information you need.

Some displays are black and white, and others provide full-color images with high resolution. Screen size will also contribute to your viewing experience. Large screens are easy to view but take up more room. If you want to mount your fish finder and be able to see it at the other end of the boat, a large screen is ideal. However, if you need to conserve space, get a smaller screen.

Customization

Customization ability is a personal preference. Some fish finders will let you change the way information is displayed, fine tune the settings, or update the display colors. It can help you maximize the contrast, making it easier to see in bright sun or at night.

Installation

Every fish finder is different. Some mount, some transmit data to your smartphone, and some are portable. The installation varies based on the type of fish finder you buy, so this is another personal preference. Whichever type of fish finder will work best for you is the type you should get.

However, if you buy a fish finder that needs to be mounted, make sure you get one with clear installation instructions, making it easy for you to set it up and get started. This is especially important if you rent boats rather than using your own. A fish finder that’s easy to mount will make it much easier for you to use it each time you rent a boat.

Our recommended fish finder installs incredibly easily and quickly. Check out this demo.

 

Water Temperature Probes

Water temperature can affect fish activity and behavior, so this can be a useful feature for all anglers. A temperature probe can lead you to areas of ideal temperatures for angling and let you know when the temperature is less than ideal, so you can move on.

Custom Maps

We’ve already discussed the importance of GPS, but did you know you can also get fish finders with custom map-making technology? If you fish in large, well-navigated waters, you most likely can find maps and navigational charts that will help you while you’re fishing. However, small rivers, creeks, and ponds are less likely to have this information already.

If you get a fish finder with this kind of technology in it, you can make your own maps for future use or upload them to the database for others to download. Unless your spot is top secret or on private property. Then you probably don’t want to share.

Removable Storage

If you and a buddy regularly alternate going out on each other’s boats on Saturday mornings, you may find it easier to simply remove your storage device and pop it into his fish finder instead of transporting the whole unit.

Fish finders equipped with SD card readers let you move your collected data from one fish finder to another. You can also upload that information to your personal computer at home or any other device with an SD card reader.
