What Should I Know Before Buying A Fish Finder
A reliable fish finder has certain features that are essential if you want a wholesome experience.
- Transducers are very important as they send out and receive sonar waves. These waves bounce off different objects once they are emitted in the water, and give you a clear direction to fish.
- Transducers materials are essential depending on the type of boat you are using. If you’re a casual fisherman, we advise you to try out the plastic transform mount. They are compatible with virtually every boat.
- The color display in your Transducer is a vital component, as they provide millions of colors and details in comparison with black and white screens that only show 265 shades of grey. A color display function makes it easier to read the information on the Transducer.
- The screen resolution feature should be at least 240 x 160 pixels. Although his resolution might not be the best you can lay your hands on, it should serve as a base value when fishing. We recommend getting a higher resolution display upwards of 240 x160 pixels.
Fish Finder Buyer’s Guide
Fish finders are effective tools that provide clear images of fish and show underwater structures in a way you have never seen before.
However, purchasing the right one can be a tough ask to the untrained eye. One small misstep can least to an unusable device.
Highlighted below are three serious mistakes you should avoid when purchasing a fish finder.
1. Buying a Fish Finder Without GPS
When purchasing a new fish finder, a novice might feel overwhelmed by all the features and options; display screen size, power wattage, Transducer, number of pixels, and many more. But remember that an essential feature you need in your fish finder units is GPS tracking.
2. Picking the Wrong Type of Sonar
The most popular types of sonar are Side Scam and Down Scan. The significant difference between both sonars is that Side Scam broadcasts an angled signal to the side of the boat while Down Scan sends the signal directly below the boat.
The third option is new technologies, like Hummingbird SwitchFire and Lowrance StructureScan that combine both Down Scan and Side Scam.
We recommend purchasing a fish finder that incorporates both of these sonars so that you can enjoy the best of both worlds for a satisfying fishing experience.
3. Picking A Portable Fish Finder Solely for Price
It is usually enticing to choose a portable fish finder when browsing fish finders. They are cheaper than fixed fish finders; however, purchasing a fish finder due to its cheapness can lead to an increase in overall cost in the long term.
Features of a Fish Finder
Choosing the best fish finder to suit your budget is an easy task. Now, you need to learn about essential features.
Display Screen
- Size Of The Screen: A fish finder unit with a broader screen provides an expansive viewing experience which is very important when fishing
- Clarity: The higher the pixels, the sharper the images. The number of pixels that a fish finder has will directly influence the sharpness and clarity of the display
- Symbols: It is important to buy a fish finder that has defined symbols for different functions
- Monochrome: If you have the luxury of spending a bit more, we recommend purchasing a model that is fitted with a color display
- Audio/Visual Alerts: This feature notices you of changes in the temperature of the fishing area
- Backlit Display: This feature provides a better viewing experience in the dark
- Sensors: Shows changes in the surface and underwater
Mounting
Majority of portable fish finders contain suction cup transducers and a self-contained case. Users can fasten the Transducer for fixed mount models to the boat ransom.
Single/Dual Frequency Transponder
- Single: Single frequency transponders emit 200kHz and operate well in inland lakes and freshwater locations
- Dual: These transponders operate at both 200kHz and 50kHz and are suited to saltwater locations as well as deep-water locations. They can penetrate dark zones and can even send strong signals beyond 200 feet
If you fish in both freshwater and saltwater locations, and both shallow and deep areas, then we recommend purchasing a model with dual frequency. However, if your angling is streamlined to a particular target, you should economy opt for a model with higher frequency
Temperature Gauge
The temperature of the water heavily influences fish behavior. Bait fishes have a preference for warm water since they are cold-blooded animals. The spot where warn levels of water meet cool levels are referred to as thermoclines.
They are prime spots for anglers, and you can see the variance in thermoclines on your fish finder screen. The higher the difference in temperature, the thicker the thermoclines will appear on the display screen.
GPS
The global positioning system features are an essential part of any fish finder device, and you will need them to pinpoint the best location to fish.
If you’re a fan of testing uncharted territory, the GPS is a useful feature to help you map your waypoints especially when you’re far from home in the dark.
GPS will also store your favorite fishing spots so you can revisit these places whenever you want. This usually comes in handy during friendly competitions. You get to angle in better slots, thus saving time and effort.
Regardless of the fish finder you purchase, GPS is a useful feature that will boost your angling experience.
