A fish finder is becoming popular day by day. It’s a very useful device. Determining the depth of water is safe with a fish finder.

It’s also a convenient device to find out the fish in a wider range of fish.

Fathometers are active instruments that are used for navigation, and this device is derived from these. Let’s know about how to use a fish finder in efficient ways.

Before we go for details let’s think about what is a fish finder.

What is a fish finder?

A fish finder is an instrument that detects reflected pulses of sound energy and so that it is used to locate fish that lives underwater.

Sometimes, people call it sonar.

The Marine Rader, compass, and GPS navigation systems three integrate and make a high degree fishfinder system.

How To Use a Fish Finder – Definitive Steps To Follow

If you’re a newbie to use a fish finder in the most convenient ways then, you should follow these steps given below.

Learn Both Fish Finder and Chartplotter

To increase your fish-finding ability, you need to know how to use your fish finder along with your Chartplotter.

At first, you need to upgrade your system into a combo unit or a fully networked system.

After you have upgraded, these systems will allow the finder and plotter to maintain constant communication.

It will also help you to record a spot’s GPS coordinates even after you have passed over it.GPS will also keep your track of where you went to find fish.

Some keynotes

  • You need both Fishfinder and Chartplotter because, without one, another doesn’t work properly.
  • You can’t give any excuse for not having a handheld GPS as a backup. So you need both.
  • It would be a twin screen system if you own this Fishfinder along with Chartplotter.

Zoom Towards Specific Area

After you have learned to use the finder and plotter together, it is time to learn how to zoom in the bottom area.

It shows up on the screen in a counterintuitive way. It will help you to determine easily that whether the boat is over a hard bottom or not.

Set Your Baits Above Thermocline

A Thermocline means temperature barriers between different layers of water.

There is a characteristic in fish, that is, they orient these thermoclines exactly the same as a solid structure.

So when do you get to know that it’s a thermocline?

You’ll know when it remains consistent at a particular depth for a long period of time. You have to set your baits at a depth that is above a thermocline.

Tune The Sensitivity

As we are in advanced age, where technology has taken over all areas, so you have to trust the technology.

Tuning sensitivity is a vital case scenario because it has an effect on water.

You have to tone down the sensitivity when it comes to turbid water, water with thick planktonic or algae growth.

This toning down can cause you to make you show a ton of clutter.

In this case, you have to reduce your sensitivity with the help of the transducer. You have to keep reducing it until most of the clutter disappears.

When it comes to adding or boosting filters to reduce surface clutter, it is a bad idea without a shred of doubt.

Because, by doing this, it will be the cause of cutting down on the finder’s sensitivity.

There’s no loss in leaving the surface clutter alone, moreover, if you can’t have a clear view of the first few feet, it will not cause you any major harm.

Change The Transducer Location

Setting all points that have been discussed above, if Fishfinder still gives you a bad result, then you have to adjust your transom mount transducer or changing its location in an entire way.

The turbulence that has been created by the boat can be the reason for ruining a Fishfinder’s performance.

So in this case, you need to change its location until you get a good result.

Final Words

There are some variables that you should keep in your mind. Such as boat speed, transducer cone issues, etc. If you want to get better at this sector, you must know the pros and cons of this and keep these points in your mind.

So, get the required knowledge on how to use a fish finder and make your fishfinder functioning in its best way.
