Fish Finders With Down Scan and Side Scan
Down imaging fish finders produce a picture-like image of what’s below your boat, using a transducer to emit high-frequency sound waves. This feature allows the user to see the shape of structures and bottom contours down to 3000 feet. These images allow you to detect fish and determine depth changes. best side imaging fish finders
While side imaging is less convenient than down imaging, it offers more detail for better picture quality. However, side imaging requires slower boat speeds and works best in shallow water. These types of fish finders aren’t as effective in deep water, but they work especially well in rivers. Unlike down scan, side imaging scanners can scan a large area without requiring the boat to go up and down each side.
Down imaging is generally more effective for deeper waters and for larger fish. However, it produces a lower quality image than side imaging. These features are more important if you plan to fish vertically. Down imaging also allows you to see where the fish are located and how they behave in different situations.
These devices can also highlight fish in different colors. These colors vary based on their depth. A fish that is deep will appear as a large arch while a fish swimming in shallow water will show as a small arch. In contrast, a school of small fish will appear as dots or short lines in the water. These devices can even highlight the colors of baitfish.
When shopping for a fish finder, consider the features and price. A high-quality down scan and side scan unit can help you see fish that are hidden in vegetation or structures. Moreover, it should be easy to set up. You should check the portability and ease of installation, as well as the instructions.
Most reputable brands include down imaging as a standard feature on their fish finders. The upgraded models also include side imaging. Those with these features are generally more expensive than those without. For example, a top-end fish finder with side and down scan capabilities can cost you several thousand dollars.
Both types of fish finders can be useful for different fishing environments. However, a side scan is more useful if you’re fishing in shallow waters. A down imaging unit will give you a fuller image, but you must be slow to get the best picture. If you’re fishing in shallow water, the side scanning function will show you where fish are hiding.
To get the best images from your side scan fish finder, you must make sure the transducer is installed correctly. This means the device should be installed at the right height and location. Sometimes, this means that you need to move the position of the transducer on your boat. An ideal location for a transducer is on a poly mounting board. Having a poorly installed transducer can have a negative impact on the performance of your boat.
Side imaging fish finders typically come with mounts, making it easy to install them on a trolling motor. However, if you use a kayak, it’s best to buy a portable model that is battery-operated and small enough to fit on the kayak. A kayak fish finder can be mounted on a dash or transom, but it’s important to make sure it’s safe and has the appropriate mounting hardware.
