Fishing is a hobby that seemed to have experienced a change in tides over the years. From being just a simple hobby that is done annually at the nearby lake in the early years, it has become a widely loved hobby turned into sport. There are two types of sea fishing – saltwater and freshwater. Open water and pier fishing belongs to the saltwater category while lake and river fishing is included in the freshwater category.

Have you ever experienced fishing with your friends only to end up with an empty bucket? Do not worry. It does happen and it can actually happen more than you would want it in the future if you do not start equipping yourself with the right gadget.

Gone are the days when it is acceptable to go home without a single catch. In the olden days, it is simply considered a bad day. Today, if you go home without a single catch, you are doing something definitely wrong. What could that wrong be?

What Is A Fishfinder?

This is actually the same technology used by submarines and ships in war. Through sonar frequency, a fishfinder is able to give a picture of what the eye cannot immediately see underneath. Sonar frequencies vary but the average would be a 200 kHz signal.

Primarily, the deeper water you are fishing from, the higher sonar frequency you need. Such units also give depth and even temperature information. Some latest models can even read 3D lake maps and consolidate it with other systems.

Best thing about a fishfinder is that it provides users the critical information needed in order to pick out the most suitable location for fishing, thus, saving a lot of time and energy for anglers and the likes.

What Happens When A Fishfinder is Equipped with GPS?

Fishfinders have already proven to be extremely helpful. Have you ever wondered why GPS devices with fishfinder capabilities are getting more buzz recently?

The addition of a GPS to an ordinary fishfinder is a major upgrade as this eliminates the need for two devices, therefore, giving the best value for your money. In fact, most fishfinder with GPS cost less when compared to purchasing a separate GPS device and a reliable fishfinder.

Fishfinders work in a way where a transducer sends out sound waves at a certain ultra-high frequency. As mentioned before, there are different frequencies available but the higher the frequency is, the deeper it can scan and give a pretty clear view of what is down under. The transducer then listens for the echo that will bounce with every object the sound wave bumps in. This process creates what are considered echoes on the screen.

The logic behind the echo is that the faster it comes back up, the closer an object is and the stronger the echo, the harder the object is.

The ultra-high frequencies are harmless and not hearable by humans or animals. For normal fishing a fishfinder with frequency around 200 kHz will penetrate the water deep enough and will still be returning high-resolution echoes.

The thing with fishfinders is that anglers would follow the track that shows where most fishes are. Common concern here is that they get lost in fishfinding that they in turn frequently lose track of where they are. This is what makes a fishfinder with GPS better. No matter how you get lost in your fishfinding activities as you follow that big fish around, you are sure to find your way back home the shortest time possible.

Most fishfinder with GPS devices today has the ability to show both the GPS and sonar on the screen at the same time or choose one to be viewed in full screen.

Things To Look For When Searching for a GPS with Fishfinder

It all seems utterly simple but truth is GPS with fishfinders can be quite complicated. The recognized brands are Garmin, Raymarine, Furuno, Lowrance and Humminbird. This is why experts suggest anglers or hobbyists to educate themselves with the modern technological features of such devices. Remember that no matter how advanced the GPS with fishfinder device you bought, if you do not know how to maximize its abilities, it would be of no use.

Here are some of the things you should know and look for when searching for a GPS with fishfinder:

  • Frequency and Power – Most fishfinders today come with dual frequency – 50/200, 83/200, and 455/800. However, if it reaches the 455/800, it is already called 3D SONAR. Power, on the other hand, is the capability of the device to send out the SONAR waves.
  • 3D SONAR – If you have the budget, we say go for the GPS with fishfinder that has this ability. This is regarded as the latest and best thing to happen in fishfinding technology.
  • Screen Size – This is another factor that affects the prices of GPS with fishfinder devices today. While larger screens are normally easier to read, bring out your checklist to determine if you really need or can afford a large screen.
  • Maps – Some brands today offer different preloaded maps for the benefit of users.
  • Navigational Data Storage and Waypoints – Most devices today can store data until you upload it to your computer or to an online platform. In addition, they also allow waypoints so that one can navigate back faster.

There is no doubt that a GPS with a fishfinder makes more sense than getting two separate devices. It is cheaper, more practical, and frankly, easier to use. Read more about marine GPS with fishfinders on
