A fish finder is a simple gadget used to locate and track the location of fish in the water. It scans through the murky waters and pinpoints the location of each fish relative to your location. It can give you information about the temperature and depth of the water.
There are many fishfinder brands, models, and types on the market. Finding the best one can be quite a challenge. To assist you to overcome this challenge, I have reviewed the best cheap finders available on the market. With this review, I believe you will be in a position to get the right choice for your fishing needs.
Best cheap fish finders – what to look for?
A fish finder is an excellent tool that enhances one’s fishing experience. It enables you to catch more fish than you could have done without it.
There are many fishfinder models and brands on the market and choosing the right one can be quite a task. The best fish finder should be able to suit your fishing needs and conforms to your fishing style. There are many factors you need to consider before purchasing a fish finder. They include:
This is the part that sends the sound waves to the water surface to show you what is underneath. It sends a sonar signal that bounces off the objects in the water and brings back the details to the transducer. This information is visible in a picture on the display. The most important feature to look out for in a transducer is the cone angle.
There are three types of frequencies you will be required to choose from. These are single, dual and multiple frequencies. Frequencies of between 50 and 100 KHz are ideal for fishing in deep waters while high frequencies are ideal for shallow waters. Knowing your fishing area can, therefore, help you choose the frequency that works well for you.
How the fish finder is powered is generally referred to as wattage. For a faster response time for your fish finder, you will require more wattage. Fishing in shallow water doesn’t require high wattage. A combination of frequency and wattage will give you a clear picture of what is under the surface.
A higher resolution gives more details just the same way the TV and computer screens work. A resolution of 240 by 160 pixels may be good for sight. A higher resolution may be required to minimize blockiness of details displayed on the screen. For clarity of picture, you will need to balance between resolution and size of the screen.
Both portable and fixed units of the fish finders are available on the market. The fixed unit will need to be mounted somewhere on your watercraft. The portable unit is a better choice especially if you are leasing a fishing boat.
