1. Before you can choose which fishfinder is the best one for you, you ought to know how a Fish Finder performs Fishfinders use sonar technology to locate fish-or any other good object-under that the surface of the water. Sonar sound waves move through the water. The further the sound waves traveling, the more they fan out into a cone shape and increase in diameter. Deeper water obviously causes the cone to become bigger as it goes out of it's origin. The form of the item struck will be determined by how long it took the signal to go out and then bounce the audio wave echo back compared to the surrounding place. The echo will subsequently show up on your fishfinder screen and you will see the aproximate size, form and depth of this object. Your financial plan will probably be another deciding factor in your choice. Figure out how far you would really like to invest on a fish finder. Then double this. That is much more realistic and helps establish a genuine budget to use. Naturally, the budget isn't the sole consideration. There are six other significant factors to help you make the best choice for you. Review all of the following: DEPTH RATING Every fishfinder is rated for a particular depth. The rating will indicate just how far down the sign will yield effective soundings dependent on the degree of the signal. However, you should know that the depth ratings given are for perfect circumstances in clean, fresh, relatively clean water; unless it says otherwise. When fishing in salt or muddy water the successful thickness will be less than said. Just like the majority of other items, however, if you want a unit that will penetrate deeper water, then that unit will cost more. My recommendation is to buy a fishfinder unit which has a depth of at least 10 percent greater than what you think that will actually need. One wants to inspect the packaging for your fishfinder carefully prior to makinf a purchase. Some fish finders come without a transducer so that you need to look at the included accessories prior to buying. So look at that at the overall price. The two kinds of transducers are single frequency and dual frequency. You will require one, the other or both depending on to what and at which you're fishing. A transducer with double frequency provides you a higher frequency transducer to get a smaller cone from deep water. As an example, a 50 kHz frequency fishfinder might have a 4 degree cone that goes deep down and provides a good view of the underside whereas a 200 kHz frequency fishfinder with a 20 degree cone would offer a fantastic opinion of the bottom in shallower water. You have to buy the right transducer, because both will generate information on your display, however you want the advice to be true. Setup of the unit also has to be factored in here. Another factor is portability; will you leave it on a single boat or move it from boat to boat. Also, you want to decide if you will mount it on the transom or undergo the hull for optimum clarity. Many companies make single frequency ducers.Most of those units are intended for use on smaller ships. They are intended for use on rivers, lakes, streams, or inland lakes. A transom bracket unit is usually simpler and less costly to install. Trasducers can be bought in both the single and dual frequency fish finder versions. Through hull transducers, on the other hand, are great for performance and clarity. However, this does require placing another hole on your boat hull for installation. And they are really only warranted if you need bottom reading at quite substantial speeds. Through the hull dual frequency transducers are advised if you plan to fish heavy water and need to read the fish in high rates. For anyone that has a little ship or will not be angling at really substantial rates, go with a portable unit or a transom bracket. The money you save will be better served by utilizing it to fill up your ship's gas tank! POWER CONSIDERATION As a rule, more electricity is always a fantastic thing. When comparing components that are equal in all other attributes, the less

2. costly unit will almost always have less power. For the best precision and clarity go to your high power as that is what determines the speed of the sonar return signals. My recommendation is to buy the highest power rating you can afford with all other factors being equal. In other words, consider units which have everything you want and then compare the energy rating of all of those units to see which one gets the highest power rating. Whenever you are taking a look at the different possibilities for the display, consider this. Color displays are easier to view in bright sunlight. Additionally, the higher the resolution, the clearer the picture you'll see on the monitor. My recommendation would be to look at several components in your price range with the features you want and then purchase the unit with the greater display resolution, in color. 480x480 is perfect, but you do not want to go any lower than 320x240. SIZE OF DISPLAY So before you really can determine the perfect display size for you, you want to measure the area where you can install the display unit. That will give you the largest display unit you are able to buy. A larger screen will equal a much heftier cost, of course. But display size is not absolutely everything. Some really great fishfinders have 4" diagonal displays and work fantastic. READ THE REVIEWS, BUT ... It is one thing to see the fishfinder reviews on the market, but hey, take them with a massive grain-or maybe a block-of salt! There is not probably anyone who has actually owned and used each of the different version they write about. More than likely the writer works for a distributor or manufacturer. Instead, start looking for impartial sources that pose the real facts. For instance, eFishBox.com has a fishfinder inspection page which shows the specifications of every one of the fishfinders made by the market brand name pioneers so you can make real comparisons based on the real capabilities. Decide based on your requirements and a solid understanding of the qualities that you require, not someone who is getting paid to endorse a particular product.
