How to Choose the Right Fish Finder
Investing in the best fish finder can help you to have the best fishing experience ever. Before buying any fish finder you should check out the key-points given below so that your money will not be wasted.
- Understanding the frequency range is important while buying the best fish finder. Basically, there are three types of frequencies, including dual, single, and multiple frequencies. Usually, they come in 50, 83, 192, or 200 kHz.
- For shallow water, higher frequencies, such as 192 or 200, are recommended.
- For deep water, lower frequencies, such as 50 or 83, are perfect.
- Higher frequency shows more details on the screen and on the contrary lower frequency shows fewer details.
- Watt is needed to know the response time of the fish finder. With the increase of the watt, the response time decreases. This means if you have more wattage you can see deeper with the small response time.
- Fishing in shallow water requires less wattage
- The result comes with the combination of the frequency range and the wattage. Keep in mind this calculation: You can read up to 400 feet deep at 50 kHz with every 100 watts of power. You can read up to 100 feet at 240 kHz with 100 watts of power.
- Screen size is not the fact to detect the fish but higher resolution is also needed. Don’t buy a fish finder which has a too much blocky screen.
- The best and larger screen will demand more budget definitely. If you don’t go out fishing regularly or periodically, you can continue with the smaller display.
- This age is colorful so don’t buy an old black and white one. Colorful displays show more detailed objects thus you can catch more. But you can also buy a black and white one if your budget is so limited or as a backup one.
- Easy readings, even on the sunlight, touch screen, zoom-in, etc. are some lucrative advantages of a colored screen.
- A transducer, the most essential instrument in a fish finder which helps to find the fish. By emitting and receiving the sonar waves, it will let you find the fish and objects. All you see on the display is the received information through a transducer.
- There’s an option to upgrade the pre-installed transducer. To receive data faster, elaborate the reading area, and faster and better work you might need to change it.
The transducer material, water-resistant, cone angles, and beams are the other features that you might consider before purchasing the best fish finder for you.
How to Use Fish Finder: Best Practices
Purchasing the best fish finder is the start of your fishing journey. Don’t get confused with what to do or how to use it properly. We’ve created a step-by-step guide to help you set up the fish finder and ready to use it.
Check the Manual
Almost every device comes with a user manual, so don’t forget to read it. If you’re not a good terms and conditions reader, simply have a rough look at the manual. Any warning should be kept in mind.
Mounting the Fish Finder
Transom, trolling, hull, or portable are some types of mounts for the fish finders. Install it in the best place on your boat, so make your own decision to choose the perfect fishfinder to mount for your boat.
Setting up the Fish Finder
Turn your fish finder on and you will get it in automatic mode with the default settings. You can let it go in automatic mode at the very beginning.
Adjusting the Settings
As you will search for the fish at the beginning, you will need to understand the sensitivity of the fish finder. Adjusting the power will let you see more detailed views. On the other hand, lowering the power will show fewer details. Try changing the sensitivity of the fish finder and you will have a very good hand at it.
Using Auto Depth
You can use auto depth until you learn about the use of sonar. Auto depth tracks the bed of the lake and tracks from upper to bottom. But you can measure (manually) the depth from a specific level which will help you by providing the proper info of the fish.
