BUYERS GUIDE

Before buying any product, it’s very important to go through the buyer’s guide, as it provides brief information and factors to consider before buying, helping you choose the best-desired product to meet your needs while fishing.

DISPLAY SIZE AND RESOLUTION

Fishfinders need to display every minor detail that their sonar picks up. Due to this, a fish radar with a large color LCD screen is ideal. Some modern fish finders are compatible with your smartphone, which can be an even better choice. It is recommended that you buy a screen with at least 240 vertical pixels and 160 horizontal pixels. Look for screens with a high-definition resolution if you want an excellent display. With these, you will get the clearest images, data, and numbers, which will be easier to read with less glare, strain, or difficulties.

WEIGHT

Any portable device’s weight is always a factor to consider when buying it. A few fit in your palm, while others require a special carrying case. To make it easy to carry, you should opt for a lightweight fish finder. Portable fish finders are often much lighter than standard or kayak fish finders, which is why they are ideal for taking anywhere and everywhere you plan to go fishing.

TRANSDUCERS

You always need to pay attention to using the transducer and how well it works. Your transducer is perhaps the most vital part of your fish finder, as it detects fish in the water by sending and receiving signals. This is the part you’re going to either mount on the boat, throw in the water, or float on top.

FREQUENCY

Transducers detect details on your fish finder by picking up the sonar waves sent underwater. More details will be picked up if your frequency is higher. It does not mean, however, that high-frequency models are always better. This will depend on the water body you prefer to fish in. It’s desirable to use a device with higher frequencies if you are working in shallow water, and It should be around 192 to 200 kHz. The best choice for deep water fishing would be a device with lower frequencies. A frequency of about 50 kHz would be appropriate.

POWER

The more watts and power your fish finder has, the faster it displays readings. A higher wattage will also allow you to use the device at a greater depth while maintaining accuracy. When it comes to shallow freshwater, power is less important. However, if you plan on going deeper, you should always have as many watts as possible on your device.
