Finding the Right GPS - Fish Finders

Posted by Sharon Kemlage on

Using GPS – Fish Finders combo can help you catch the most fish in the shortest amount of time. It allows you to see fish and structures underwater that you never knew were there. However, buying the wrong fish finder can make it ineffective and even unusable at times.

 Buying a fish finder without GPS is a big mistake. The GPS is the first feature you need to consider before power wattage, display screen size, number of pixels, and other factors. The GPS system allows you to get home safely. It provides you with the coordinates when needed. The GPS system also allows you to make your own map.

 Now that you know the advantages of using GPS – fish finders, it is time to learn about the other features that you should consider when buying GPS navigation for boats.


 The frequency of the device depends on where you are fishing. Low 50 kHz transducers work best in deep water and used by professionals and commercial anglers. 192 and 200 kHz are ideal in shallower water.

 Keep in mind that the higher the frequency, the more details are seen on the display. This is because the transducer sends out and receives more sonar waves. There are high-end fish finders that have more than 400 kHz and multiple frequencies. That means users can switch between frequencies to provide them a range of views, from general to more detailed views.

 Power of GPS Device

 Power is an important factor to consider when buying a GPS – chartplotters. You can find devices in every specification so that you can find the right one that fits your boat. The higher the wattage, the faster the unit can show readings and the deeper they can be. Lower wattage device is slower and recommended for shallower waters.

When there is less power, the sonar waves are slower, and reading will be fuzzier. If the device has greater wattage, then the waves are much faster, and the reading is clearer. The shallower the water, the less power is required. If you plan to go fishing in deep water, it is ideal to get the most power that your budget allows you.

 Types of Screens

 When it comes to screens of GPS – fish finders, one of the factors to consider is their screen resolution. The number of pixels on the screen is important. The higher the number of pixels, the more detail you see on the display. At 240 x 160 -screen resolution, the image is boxy. You need to invest in a higher-resolution screen for crisper, sharper images.

 The next option is whether you want a colored or a black-and-white screen. Color screens provide more detail compared to gray-scale screens that only show different shades of gray. Color screens are also easier to see in all types of lights compared to black-and-white screens.

 Keep in mind that there’s single solution when it comes to GPS- Fish Finders. You need to do your research to find the right model that suits your lifestyle. Choosing the right one will result in better effectiveness while fishing.
