With so many fish finder brands in the market currently, it can be quite challenging to choose the right device that will meet your personal needs .To make the process easier for you, below are some of the things that you need to keep in mind when buying a fish finder. The Model There are three main models of fish finders: GPS Combination Units, networked and standalone fish finders. A standalone fish finder will let you see what is below while giving the largest display area and great performance at a very low cost. If you have a small fishing boat and you are on a limited budget then this is the right fish finder for you. GPS Combination Fish finder uses sonar to view the underwater and GPS to navigate the fishing grounds.
The GPS usually marks areas where fish are hiding as underwater debris or wreck. This fish finder is good for midsized boat owners. A networked fish finder supports a wide range of data sources e.g. video, Sirius XM Satellite Radio, raster & vector GPS-Charts and radar. A networked fish finder can be integrated with other systems such as Wi-Fi or Bluetooth and you can be able to control them from a Smartphone. Fish finder products from Lowrance, seem like a good choice for many fishermen.
Transducer The transducer is the main component of a fish finder. It is used to send sound waves and to show what is under the water. When you are checking the transducer, the part that you should concentrate on is the cone angle. For a wide perspective, choose a transducer with a big cone degree. However, a cone with a wide perspective cannot penetrate water as deeply as the narrow cone. To get the most in terms of depth and perspective, choose a dual beam transducer. Display The display of a fish finder is all about pixels.
The more pixels a fish locator has, the more clearly you will be able to see details underneath the water. Various fish finders have various display models in terms of resolution, size and color. A large display screen delivers clearer and great images. You can choose a colored or black & white display. Colored display is easier to view and it gives amazing details of what is under the water.
However if you are on budget, a black and white display is just fine. Power Power is one of the essential features that you should consider when choosing a fish finder. A fish finder with high wattage has a fast display speed of the readings and it’s very effective for deep waters. If you are fishing in shallow waters, you can use a fish finder with less wattage e.g. 600 watts. Frequency Choose a fish finder with the right frequency because the level of frequency is usually directly proportional to the cone angle.
Most transducers have frequencies of 200, 192, 83 and 50 KHz. High frequency delivers more details on the screen. Some fish finder models have dual, single or multiple frequencies. Fixed or Portable If you are a watercraft owner, the best choice of a fish finder should be fixed. You can mount it once and for all in any location of the boat. However, if you usually rent the fishing boat, a portable device is the best choice.
