GPS Fish Finders – Choose it, Use it, And Love It
Electronic fish finders are so affordable now that every fisherman can take advantage of these awesome devices.
No more guessing where to find the catch of the day.
These days, fish finders are more advanced than ever. Even small boats can use them thanks to their compact and durable designs.
Let’s talk about how this handy device can help you catch more fish than you ever thought possible.
The transducer is the key to the effectiveness of a fish finder. GPS fish finders emit a signal that communicates with the GPS satellite orbiting the earth. The transducer is what emits the sonar signal in a cone shape and transmits the data back to the screen where you can see it. By bouncing this signal, you can see the bottom of the body of water as well as underwater structures and weeds. Not to mention you can see the fish!
Many fish finders use a dual beam sonar. One beam is sent at 60 degrees to find the fish and the other is at 20 degrees to accurately display the bottom of the body of water and its structure. The GPS satellite returns a signal to your fish finding device that produces a three dimensional image of the water beneath your boat.
The sonar can locate the fish and display their images on your screen using this three dimensional image. As you troll over a body of water, the GPS/fish locator/depth finder will constantly update details and images of the water underneath you.
A lot of the smaller units have transducers that fasten to a suction cup so they can adhere to almost any surface.
These models are ideal to use in small vessels like speedboats, canoes, and even inflatable boats because they are light enough and compact enough to go anywhere.
If you own a larger boat and are buying a fish finder then it is most important to figure out where to mount the components. This will give you the best performance from your device. Try to find a permanent location that is easily accessible to you when you install your fish finder.
Most fish finders come with a standard mounting bracket and transom mounting transducers. Ideally, the fish finder should be mounted somewhere convenient like near the steering wheel or drivers seat.
So that the sonar signal can do its depth finder job and scan the water even while you’re moving, it is best to mount your transducer in a spot where it will be submerged both at low speeds and high speeds.
Most fish finders are push button easy. After turning on the instrument, digital readouts will show up on the monitor. These readouts will usually represent boat speed, water temperature and depth depending of course on the model you have chosen.
The line running across the bottom of the screen represents the bottom of the body of water you are boating on. The waves on the screen reveal the terrain on the bottom. A thin, light line indicates a soft bottom whereas a thick, dark line signifies a hard bottom. Fish will be indicated by icons or arches.
Make sure the electronic fish locator you purchase is durable. Look for ones made from hard plastic that can withstand tough elements and wear and tear. It’s important to remember that water resistant doesn’t mean waterproof. Most GPS fish finders are completely waterproof but the monitor can sustain serious damage if submerged for long periods of time. Cover your monitor when not in use and don’t leave it in a place where water is likely to accumulate.
To keep the monitor clean, use a lint free cotton cloth and a small amount of warm water. Avoid using any harsh cleaners, such as a window cleaner. Some models will come with a stretch neoprene cover to help prevent water damage. You can usually find lots of accessories for your unit such as protective case that will cover the mounting assembly.
There are a lot of choices out there for you as far as GPS fish finders go. These products can range in prices from under $200 to $2500. Do your research and choose the product that is right for you and your needs, but also consider how much you are willing to spend. Just remember though, that you usually get what you pay for.
