1. Before you can decide which fishfinder is the very best one for you, you ought to be aware of how a fishfinder performs Fishfinders utilize sonar technologies to locate fish-or any other good object-under the surface of the water. Sonar sound waves move through the water. Deeper water obviously leads to the cone to become bigger as it moves out of it's origin. Whenever the sonar wave strikes against a good object of any substance, it will bounce an echo back to the transducer. The form of the item struck will be decided by how long it took the signal to head out and then bounce the audio wave echo back compared to the surrounding place. The echo will then show up on your fishfinder display and you'll observe the aproximate size, shape and depth of the item. Your budget will likely be another determining factor in your choice. Figure out how much you would really like to invest on a fish finder. Then double that. This is much more realistic and helps set an actual budget to use. Naturally, the budget is not the sole consideration. There are six other vital factors that will assist you make the best selection for you. Review All the following: DEPTH RATING Each fishfinder is graded for a particular depth. The rating will indicate how far down the signal will yield effective soundings based on the degree of the signal. However, you should be aware that the thickness ratings given are for perfect circumstances in clean, fresh, relatively clear 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, but 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 thickness of at least 10 percent greater than what you think that will actually need. IS THE TRANSDUCER INCLUDED? One wants to check the packaging to your fishfinder carefully prior to makinf a purchase. Many fish finders come without a transducer so you have to look at the included accessories before buying. So look at that in the general price. You will need one, the other or both predicated on for what and at which you're fishing. A transducer with double frequency gives you a higher frequency transducer for a smaller cone in deep water. For instance, a 50 kHz frequency fishfinder might have a 4 degree cone which goes deep down and provides a fantastic view of the bottom whereas a 200 kHz frequency fishfinder with a 20 degree cone would provide a fantastic view of the bottom in shallower water. You need to purchase the correct transducer, since both will generate information on your screen, however you want the information to be accurate. Installation of the unit also has to be factored in here. Additionally, you need to decide if you'll mount it to the transom or go through the hull for optimal clarity. Several companies make single frequency ducers.Most of those units are meant for use on smaller ships. They're meant for use on rivers, lakes, rivers, or inland lakes. A transom bracket unit is usually simpler and less expensive to set up. Trasducers can be purchased in both the single and dual frequency fish finder models. However, this does require placing another hole in your boat hull for setup. And they're really only warranted if you require bottom reading at very high rates. Throughout the hull dual frequency transducers are recommended if you're planning to fish heavy water and will need to browse the fish at high rates. For anyone that has a small boat or won't be fishing at really substantial rates, go with a mobile unit or a transom mount. The money you save will be better served by utilizing it to fill up your boat's gas tank! POWER CONSIDERATION

2. As a rule, more electricity is almost always a good thing. When comparing units which are equivalent in the rest of the features, the less costly unit will nearly always have less electricity. For the best precision and clarity go to your high power as that's what determines the rate of the sonar return signals. My recommendation is to buy the highest energy rating you can afford with all other factors being equal. In other words, consider units that have whatever you want and then compare the energy rating of all of those components to determine which one has the maximum energy rating. DISPLAY - SCREEN AND RESOLUTION Whenever you are taking a look at the various possibilities for the screen, consider this. Color screens are easier to see in bright sunlight. Also, the higher the resolution, the clearer the image you will notice on the screen. 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 screen resolution, in color. 480x480 is ideal, but you do not wish to go any lower than 320x240. SIZE OF DISPLAY So before you really can decide the perfect display size for you, you need to assess the area where you will install the display unit. That will give you the most significant display unit you are able to purchase. A bigger screen will equal a heavier cost, obviously. But display size is not absolutely everything. Some really great fishfinders have 4" diagonal screens and work fantastic. It is 1 thing to see the fishfinder reviews out there, but hey, take them with a huge grain-or possibly a block-of salt! There is not likely anyone who has actually owned and used each of the different version they write about. More than likely the author works for a manufacturer or distributor. Instead, look for impartial sources that present the real facts. As an example, eFishBox.com includes a fishfinder review page which shows the specifications of every one of the fishfinders made by the market brand name leaders so you're able to make real comparisons depending on the actual capabilities. Decide based on your own needs and a good comprehension of the features you need, not someone who is getting paid to endorse a specific item.
