The Importance Of Having A Good Fish Finder On Your Boat

Fishing is an amazing pastime to say the least. If you are like most people who fish you find it to be fun, challenging, relaxing and a great way to bond with family and friends. It also is a sport that takes skill, technique and can be very demanding at times.

There are so many types of fishing and each one will require you to master certain skills. The only problem is all the skill in the world will not matter if there is no fish in the area of a lake, river or ocean where you are fishing. That is why it is so important to have a good fish finder on your boat.

What is the best fish finder? That is an easy question to answer. It is a fish finder that is accurate and will get you to an area that has a large fish concentration in a hurry. A good fish finder will help you with such things as lure selection, line weighting and even help you determine what type of fish you are most likely to catch on a particular day.


How Does A Finder Work?

You may be like many anglers and wonder just how these amazing fishing devices you have heard of work. There is nothing magic about them they just use simple science to give you a better chance at having a successful fishing adventure.

They are a device that uses sonar waves to help you determine when fish are present. They have a receiver unit that is much like a computer screen that is placed near the pilot area of a boat and a transmitting unit (called the transducer) that is installed on the bottom of your boat under the water line.

When the fish finder is activated the transducer starts sending out sonar signals which are sound waves that will travel until they hit a solid object then reflect back. The timing of the reflected sound wave coming back is how size of an object and its distance away is determined. It is the same type of technology that the military uses to find enemy submarines.

The sound wave information that is reflected is then displayed on the screen that is mounted near the pilot area of the boat. Not only can this information help improve your fishing but it can also alert you to such hazards as rock outcroppings, shoals and rapid depth changes underneath your boat.

Myths About Fish Finders

Here are a few common misconceptions about fish finders that you should know:

  • They will tell you what type of fish they are detecting

As we mentioned before the only thing that a fish finder will really indicate is the concentration of fish in an area and the approximate size of those fish.

It cannot tell you if they are bass, pike or salmon; but these things can be determined if you know the indigenous fish habits of the area you are fishing and combine that with the fish finder information.

  • They cannot be used in shallow water

This is a myth. Sonar is sonar. Whether the water your boat is in is shallow or deep the sonar will go down and hit an object and send that information back to you regardless of depth.

  • They don’t always work

Once again sonar is sonar. When a sound wave is sent out from the transducer it will travel until it hits something that will reflect the sound wave back.

A fish finder is not foolproof but it’s a pretty good bet that when you are getting small sonar hits there is fish under your boat. They are very accurate in a majority of the instances they detect the presence of fish.

What To Look For In A Fish Finder

Fish finders come in all shapes, types, sizes and price ranges. With as popular a pastime as sport fishing is you can imagine just how many choices you will have in the marketplace. Make sure you take a look at the key attributes of any fish finder you are thinking about buying before you make that purchase.

It can make a huge difference in purchasing a fish finder that works great and leaves you happy you spent the money on it.

Here are some of the key attributes that you want to take a close look at on any fish finder you are thinking about purchasing:

  • Price

The best fish finders are not always the most expensive ones so don’t be misled by price. It may be a good indication though of what features that a fish finder has that may be useful to you.

You should set a budget for the amount you are willing to spend on a fish finder before starting your search too. This will keep you from wasting time looking at ones that are out of your budget range.

  • Wattage

A fish frequencies power is displayed in watts. You may wonder what this has to do with a fish finder you are thinking about purchasing. It is actually a very critical factor in determining fish finder quality.

The higher the wattage a fish finder has the faster the signal of what is in the water under the boat gets back to you; that means the higher the wattage on a fish finding unit the more accurate and up to the second the information is that you are receiving on the display.

So make sure you do not underestimate the importance of wattage when it comes to making your fish finder purchase.

  • Frequency variety/Cone angle

The more frequencies a fish finder has the better versatility it has as far as helping you find fish. High frequencies (192 KHz and 200 KHz) are great for using in shallow water and lower frequencies (such as 50 KHz) work best in deeper water.

The number of cones and cone angles are also important too. The more cones the more area coverage underneath the boat you can detect if there is fish there.

The number of frequencies and the cone angle are two things that are very important to consider when shopping for fish finders.

  • Display/Screen resolution

The more screen resolution your fish finder display has the more information it can display for you. The more information you have on the fish around your boat the belter decisions you can make on how to catch them. Also a color display is usually better than a black and white display in most cases too.
