Fish Finders - It Is A Great Addition To Other Fishing Gear

August 5th, 2010

The portable fish finder detects the presence of fish and their depth. Early fish finders simply flashed to indicate the presence of fish. As a fish moves through the sonar beam of a fish finder,a mark specific to that fish species appears on the chart display.

It’s important to remember that if the wire between the screen and the battery gets damaged, the fuse will blow. The wires need to be routed and secured under the gunwale up to the screen mounting location. The fuse is protecting the fish unit and its wiring. The fuse for the fish finder needs to go as close as possible to the battery. With a little patience it is a do it your self job that you can tackle.

Most people are happy with the LCD fish finders. CRT displays work great but they require a lot of power and they cost a lot more. I don’t think a CRT finder give you enough value for you money. LCD finders locate the fish just as well as the CRT finders.

When you are looking at several different fish finders there are two differences in screens. The first type of screen is called the Cathode Ray Tube (CRT) the other is called a Liquid Crystal Display (LCD). CRTs have become increasingly less popular since the invention of the LCD screens. This is because LCD screens are able to display high resolutions. If you see a TFT screen it is just another version of the LCD screens.

For the average fisherman the CRT screen is your best choice. It’s cheaper than a CRT unit and provides very good clarity and can be read well in direct sunlight.

Another thing you need to think about is whether or not you want to have a global positioning included in your fish finder. GPS fish finders are great for going on those weekend trips or somewhere you may not know your way around very well. You can easily record any position in the system and the GPS fish finder will be able to locate it again for you without problems.

Highly Refined Sonar Technology Is Being Used Into Today’s Fish Finders

August 5th, 2010

Highly refined sonar technology is being used into today’s fish finders. Sound waves allow these modern day units to give the fisherman a clear image of rocks, stumps, gravel and, of course, the fish. This is a big advantage when fish are migrating or weather conditions have suddenly changed causing the fish to be on the move.

Some features allow you to see the fish better in shallow water, deep water, off the side of the boat, black and white screens or color screens, different screen sizes, screen refresh at different intervals, user settings memory, battery voltage indicators and more.

A good feature that is found in some fish finders is GPS technology. This allows the fisherman to mark his or her location so they can return to a good spot later or let you get back to where you started if it gets dark or fog should set in.

A cone angle of the transducer circumscribes the area covered by the device. In shallow and medium waters, wide cone angles will suffice, whereas in deeper areas, narrow angles are more useful. A sonar unit’s depth coverage will be affected by the power of its transmitter, its receiver, sensitivity and frequency, as well as the transducer and how it is installed. Additional factors that impact a depth finder’s range include the kind and condition of the water, as well as conditions on the bottom of the body of water.

In order for your device to work at an optimal level, you will need be sure that the transducer is installed properly. The majority of transducers that are permanently attached are those meant for high-speed use. In order to achieve optimal performance, transducers ought to be affixed to a spot that will expose the face to a smooth, constant flow of water under any speed condition.

When Looking For A Fish Finder, Consider Where You Will Be Fishing Most Ofter

July 29th, 2010

There are literally 100s of fish finders to choose from, and you do not want to spend money on one that you will not get your use out of. Fish finders can be mounted to large boats that will be out in deep waters, or smaller boats for lakes and rivers.

It is important to consider how deep the water will be, where you plan on fishing most often. Some of the models can only measure a couple hundred feet. If you are looking for a bigger screen, color, and better resolution, be prepared to pay more.

Generally, higher frequencies gives the best detail, and works best in shallow water and at speed. Target definition is also sharper with these higher frequencies. This is the ability to show two fish as two separate echoes instead of one single mass on the screen. In short, it works well for depths of less than 200 feet and for getting an accurate reading while moving faster.

Color Display Fishfinders Will Assist You Locating Fish Even In Bright Sunlight

July 21st, 2010

Garmin 400C FishFinder comes with a dual beam 80/200 kHz transducer that allows for depth penetration of up to 900 feet. This transducer is best suited for freshwater fishing due to its depth penetration.

If you plan on going salt water fishing, it is recommended to upgrade to a separate dual frequency transducer. The dual frequency model will penetrate up to 1500 feet and has cone angles of 45 degrees and 10 degrees depending on the setting. As with the dual beam transducer you will see a wider area at more shallow depths, but with this transducer you will be able to spot those hard to see fish up to depths approaching 1500 feet.

Fish finders are gadgets that help to determine the depth of water from a boat and detect if any objects are present in the water. The transducer sends a conical sound wave, called sonar, which travels through the water like an expanding cone. Whenever any obstruction comes in its path, it reflects back the sound wave to the transducer. The time taken for the sonar to return helps to calculate the distance of the object from the transducer.

The depth rating is another point to be considered while choosing a fish finder. Try to go for one that has at least 10% more depth range than what is required by you. The cost will increase with the depth rating, but will give you better penetration in the deep murky waters.

Fish finders also come as portable, transform mount or through hull installation. If you want to use it on several boats, a portable transducer is what you are looking at. Through hulls provide you with the best clarity and performance needed for deeper waters, whereas transform mounts and portables are much cheaper and well suitable for shallow waters.

A power rating is critical factor. Any fish finder with a higher power rating will have a much better performance, but cost more money. The clarity and the speed depend hugely on the power rating. The display resolution also affects the cost. A clearer or a colored display will provide a better picture and will cost more.

The Colored Fish Finder Is Easier To Read

July 16th, 2010

Generally, a fish finder is used by fishermen who fish in boats. A sensor helps in shooting sound waves into the water and this is called as a transducer.

A transducer helps in converting electronic pulses that are emitted by the fish-finder to sound waves that travel down through water. When these waves hit the terrain or a fish, the echo that is returned is picked by the transducer that converts it into electronic pulses. The fish finder converts these pulses into a picture. When the pulse has a higher frequency, the resolution of the image is also better.

A fish finder is made for the angler to be able to identify structure, depth and fish under and, with the new technology, all around the boat. There are two types of fish finder displays or screens, a color or a monochrome fishfinder. The color fishfinder is much easier to see during the day than the monochrome fish finder. The color combo models also plot much faster, especially with the broadband technology that exists in the new Lowrance HDS fish finder models.

Obviously, the color fish finder is much easier to read. When you look at the screen of the fish finder, it will show 3 colors red, yellow and blue. The blue is the easy one; it is showing the water under the boat. The red on the screen shows the top of the water and anything dense underneath the boat. If you see arches under the red balls it means the fish are pushing the bait towards the water surface.

The black and white fish finder works just like the color fish finder but is much harder to read for the recreational angler, especially in the daylight. Like the color fishfinder, it shows the bottom and top of the water underneath the boat.

It doesn’t show the density of what is underneath the boat, the monochrome fish finder just shows the bait balls and the arches. It only shows them in black, which makes it harder to differentiate between the bottom and what is actually fish. Also, the monochrome fishfinder choices usually come in smaller size screens than that of the color fish finder models.
