Things To Consider When Buying
You may have noticed that some fish finders come with single, dual, or multiple frequency transducers. This is something you should think about carefully because frequencies are among the most significant factors.
The higher the frequency, the more detailed image you’ll get. It’s because this type of unit sends more sonar waves and receives a more accurate image.
High frequencies are the best choice if you’re fishing in shallow water. On the other hand, if you’re fishing in different types of water, you might want to consider a finder with multiple frequencies. It’s up to you to decide since even a single frequency is fine if you fish in only one type of water.
Power is another vital thing to think about depending on where you fish and how you plan to use the finder. Luckily, the market is packed with different units that range in features and specifications, power being one of them.
The higher the wattage, the quicker you’re going to see the information readings. Plus, this also affects its depth, so the greater wattage allows the unit to go deeper in the water.
Less wattage means a slower unit which is better for shallow water. So, think about if you’ll be in shallow or deep water. Deeper the water, more power you’ll need.
Screen resolution may not seem like the most critical factor to consider. However, it’s quite important since more pixels allow a more precise image that’s easier to read. If you want a sharp image and clear results, you should look for more pixels.
A general rule is to go for at least 240×160 which is considered a minimum. This is far from enough for a sharp image, but it’s the least you should think about.
If you’re a bit more serious about the image quality, you should consider a bigger screen and more resolution. These units usually cost a bit more money but deliver quality and sharp images that are easy to read.
Color is a relatively new addition to these units that used to be basic black and white a while ago. With color, you get better detailing and an image that’s easier to read. Different information is shown in a different color which is far better than what you’d get with a b&w screen.
Color on a fish finder allows you to see all the information with more detail. This helps to see and understand what’s happening in the water and it’s much easier to read in direct sunlight.
Transducers are among the most important things to look for when buying a fish finder. It’s the part of the unit that emits and receives the sonar waves.
A transducer sends the signals to the water and then picks them up once they bounce off of the underwater objects. The information is then sent to the main unit that converts it into a picture. As a result, you get an idea of what’s happening under and around your boat with different accuracy.
Most units come with transom mount transducers that are easy to mount, install and use.
How Does a Fish Finder for Small Boats Work
You should first know that there are three different types of imaging that range in purpose and accuracy. They work with sonar systems and create an image depending on the particular sonar. Because there are pros and cons to each of them, you should carefully consider all three of them.
These fish finders are simple and have a cone of sonar beamed down into the water. They deliver a rough image of what’s below and show fish as arcs.
Standard sonar type was first used in fish finders and as such isn’t the most accurate. Over time, they did become more sophisticated but are still the roughest of the three types. These don’t always show the most precise information about fish, depth, temperature and other stuff.
Still, they work reasonably well once you figure out how to read them. There’s a learning curve, but once you get the hang of it, you’ll find the unit quite useful.
Side Imaging is different than the other two. It focuses on sending beams to the side of your boat which means you’ll see less of what’s below.
It’s quite useful for finding structures around your boat. Instead of just seeing below the boat, you can now see around for more information and easier fishing.
The great thing is that you can find the technology built in along with the other two types. If not, you can also purchase a separate unit with side imaging. In most cases, side imaging works the best when it’s combined with the other two technologies.
Down Imaging is much like the standard sonar but a more sophisticated version. The difference is in the fact that this one shows a more accurate image of what’s below your boat.
For this reason, it’s a bit more expensive, but it’s also more accurate and easier to read. You’ll be able to see fish, weeds, rock and whatever other structure below the surface of the water.
Since it’s as accurate, it’s a great option for beginners and professionals. However, it takes a while to learn how it works and how to read the information it shows.
Benefits of Using a Portable Fish Finder
There are several benefits of using a portable fish locating device. If you compare them with fixed finders, you’ll find that the portable ones carry a few extra pros.
Convenience – portable units are easy to transport, and you can use them in different locations. It’s a perfect choice for you if you’re fishing from land, a kayak or a rented boat.
Ease of use – it’s relatively simpler than a fixed finder since there’s no installation required. You just set it up before use which takes a few seconds.
Affordability – they usually don’t cost as much as fixed fish locating devices.
Transducer flexibility – you can mount the transducer on a kayak or a boat. Also, you can throw it into the water from the boat, shoreline or the dock.
When you’re shopping for a fish locating device for a small boat, there are a few things you should consider. Size is only one of the few important factors that determine whether the unit will work for you or not.
Still, as you can see from our list, these units are quite versatile. They come in different sizes and have several various features to choose from depending on your needs and preferences.
If you’re unsure which to pick, we suggest you take a second look at the Garmin Striker 4 with Transducer. It’s easy to use and has a color display. Also, you won’t struggle with reading the information in broad daylight which is often an issue for other fish finders.
Still, the choice is up to you, so think about your needs and preferences before opting for one of the devices above.
