How To Choose The Right Fishfinder For Small Boat
-
Frequencies
You may have noticed that some fish finders come with one, dual, or multiple frequency transducers. This is something you should consider with care because frequencies are among the most important factor to consider before choosing a Fishfinder.
The higher the frequency, the better detailed image you’ll get. It’s because this type of unit sends more sonar waves and receives a more accurate image.
Its best to go for high frequencies if you’re fishing in shallow water. On the other hand, if you’re fishing in various 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
Power is another crucial factor to think. The one you pick should depend on where you fish and how you plan to use the finder. Luckily, the market is stocked with different units that range in specifications and features, power being one of them.
The higher the wattage, the faster you’re going to see the information readings. Also, this also affects its depth, so the greater wattage allows the units to go deeper in the water.
Less wattage means slower units which is better for shallow water. So, think about if you’ll be in deep or shallow water. The deeper the water, the more power you’ll require.
-
Resolution
Screen resolution may not seem like the most vital factor to consider. But, it’s quite crucial since more pixels allow a more precise image that’s easier to read. If you want clear results and a sharp image, you should look for more pixels.
A common 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 little more serious about the image quality, you should consider a bigger screen and more resolution. These units cost you more money in the bank but deliver sharp and quality images that are simple to read.
-
Color
Color is a relatively additional new feature added to these units that used to be basic black and white a while ago. With color, you get better image and detailing that are easier to read.
Different information is shown in varying colors which is far better than what you’d get with a b&w screen.
The color on a fish finder allows you see all the detail and information. This helps to grasp and understand what’s happening in the water and it’s much easier to read in direct sunlight.
-
Transducer
Transducers are among one of the most important things to look for when purchasing a fish finder. It’s part of the unit that releases and receives sonar waves.
A transducer sends the signals to the water and then picks them up as soon as they bounce off of the underwater objects. The information is then sent to the main unit that turns it into a picture. With this, you get a vivid idea of what’s happening under and around your boat with varying accuracy.
A lot of 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 3 imaging types that range in accuracy and purpose. They wok hand-in-hand with sonar systems and create an image depending on a specific sonar. Because there are advantages and cons to each of them, you should carefully consider all 3 of them.
-
Standard
These fish finders are easy 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 types first came with fish finders and as such isn’t the most accurate. Over time, they did become more sophisticated but are still the roughest of the 3 types. These don’t always show the most precise information about temperature, depth, fish and other stuff.
Yet, they work fine as soon as you decipher how to read them. There’s a learning curve, but once you get the hang of it, you’ll find the unit pretty useful.
-
Side Imaging
Side imaging is different from the first two. It main goal is 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. It makes you see what’s around for easier fishing rather than focus only on just seeing below the boat, you can now see around for more information and easier fishing.
The best part is that you can find the technology built in along with the other 2 types/ If not, you can also buy a different unit with side imaging. In most cases, side imaging works the best when its combines with the other 2 technologies.
-
Down Imaging
Much like the standard sonar, the down imaging is a more sophisticated version. The difference is in the fact that this one shows a more accurate image of what’s under your boat.
Because of this, it’s a tad expensive, but it’s also more precise and easier to read. You’ll be able to see weeds, rocks, fish and whatever other structure of what’s below your boat.
It is accurate, and a great option for professionals and beginners. But, 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 countless benefits of using a portable fish locating device. If you compare them with fixed finders, you’ll find that the portable ones carry more advantages.
Convenience – portable unites make transportation easier and you can use them in varying locations. It’s a perfect choice for you if you’re fishing from a rented boat, a kayak or land.
Ease of use – It’s simpler than a fixed finder since there’s no installation required. You just set it up before use which takes a couple of seconds.
Affordability – they usually don’t cost as much as fixed fish locating devices.
