The area directly under your boat and extending 20 to 25 feet to either side will be blank or black, representing what is essentially a blind spot. This result comes from the sonar aiming to the sides of your boat. On either side of the black or blank area is the underwater terrain and fish off to either side of your boat. The line represents the path your boat is on. There’s a bright line down the center of the screen, surrounded by a black area. With Side Imaging, what you’ll see on the screen appears to be a split screen at first glance. There’s also very little side information in a Down Imaging fishfinder. This means you get less information and the images receive have a lower resolution. This system relies on a single transducer. In contrast to its name, the image produced from Down Imaging shows the terrain surrounding the boat. It also produces reliable images even when you’re moving at high speeds. With Down Imaging, the sonar returns a picture of the lake or river bottom that is directly under your boat. Here, we’ll use the Humminbird nomenclature. Other manufacturers, such as Garmin, use DownVü and SideVü, while Lowrance uses DownScan and SideScan.ĭespite the differences, the names all mean the same thing. Each type has its own unique advantages and disadvantages.īefore we go any further, you need to understand that Down Imaging and Side Imaging are names that are proprietary to Humminbird. Some more expensive models have both types. Humminbird fishfinders come with two types of imaging: Down Imaging and Side Imaging. No matter your preference, Humminbird has a model that will meet your needs. Many of their models include both buttons and touchscreen controls. While touchscreens are more common in their more expensive models, some anglers prefer the simplicity and reliability of button controls. Humminbird fishfinders use either touchscreen controls or button control systems. Their SD cards may come loaded with their Humminbird Basemap cartography system if the model you purchase does not have Humminbird Basemap installed. Humminbird fishfinders may have microSD or SD card slots, but not all models support external memory storage. Perhaps most importantly, an SD card slot allows you to access maps of your favorite fishing areas. This is where an SD card slot comes in handy. If you want a trip log to keep track of where you’ve been, where you found the fish, or what the bottom of the lake or river is like, you’ll need some memory on your fishfinderinder. If you’re a kayak angler, however, that extra weight can become a hazard or can at least cause your craft to list slightly. On a large boat, it won’t make any difference. Other, larger models can top out at 14 pounds or more. Some Humminbird fishfinders weigh in around 2 to 3 pounds (between the display and the transducer). Weight isn’t quite as much of an issue because fishfinders will typically be bolted to your boat. Unless you’ve got money to burn, at some point you’ll have to make a trade-off between what you can see versus how much you can spend. However, a larger screen is a more expensive screen. It will be easier to distinguish the difference between a school of small fish and one or two large fish, see where the bottom is, find the thermocline, and learn other important details. Humminbird screen sizes, measured diagonally, vary from around 4.5 inches to 15 inches or more.Ī larger screen is easier to read and gives you more detail. You should read through it before your first outing to make the most of your fishfinder. Nonetheless, the manual is included for a reason. Humminbird fishfinders are fairly intuitive.
