Marine fish finders are high-tech gadgets that can help you locate fish through new age technology. Have you have ever wasted an entire day looking for a good place to start fishing, only to realize there was nothing there all along? If so, you can appreciate the idea of a marine fish finding device. How does such a product work?

Fish finders are actually fathometers, which operate via echo sounding and active sonar technology. Marine fish finders send out an electrical impulse from a transmitter which is then converted into a sound wave. It is sent to the water and will strike against objects, sending back information on the object’s size, composition and shape. From the data it relates, you can deduce whether or not the object is something stationary or perhaps a living fish.

The accuracy of such a device will depend on the power of the system and pulse it sends out. The data that it sends back will be displayed on a monitor. This device could help fishermen cut their searching time in half, leaving them more time to concentrate on catching their trophies. Some high-priced Marine fish finders may also be able to show depth and sound, as well as chart plotting data, and electronic compasses. Some fish finders can be connected to a radar navigation device for even more accurate fishing expeditions.

Keep in mind that some marine fish finders are cheap for a reason. They may only offer location information so that you can keep track of your moving patterns and your coordinates. After all, some products are less than $100. However, other devices can be $1,000 or more, presumably because they actually offer a fathometer and GPS technology combined. Some models of marine fish finders may be complex to learn, while others remain relatively simple, perhaps just like an ordinary GPS car device.

You may notice that some models have LCD screens while others have CRT screens. Are there any advantages or disadvantages that come from one or the other? Unlike with television sets, LCD displays for fish finders are actually cheaper than CRT screens. In addition, LCDs are usually waterproof and less fragile overall. The main advantages of CRTs are that they can produce a clearer picture. However, they are also more easily prone to breaking and water damage.

Obviously budget is a concern when choosing your marine fish finders. Some would rather invest in other products, electronic and perishable, so that they can focus more on natural fishing than put too much into high-tech devices. You do have to walk a fine line here. After all, fishing finders do not help improve your technique; they merely prevent you from wasting too much time in one unproductive spot. You could look into black and white or grayscale screens if you are looking to save money.

Marine fish finders do help to make your fishing expedition more enjoyable and far more products. For more information on where to find these finders, look up marine retailers or type in the name of the model you are interested in for some reviews.

There are many different types of bass in our area such as small mouth, large mouth, and stripe bass, which can weigh as much as 40 pounds, to name a few and as the temperature gets colder in the winter the fish migrate deeper in the water where they can stay warm.  Some large mouth bass have been catch in water as deep as 50 feet and the use of a fish finders greatly improves your chances of locating the biggest fish and catching the trophy fish you’ve always’ wanted to put on your wall.
We have many different lakes in our area such as Smith Lake which is located 20 miles northwest of Birmingham Alabama.  The dam is 300 feet high and the lake is feed by the Black Warrior River with many other small streams contributing when we get heavy rains.  It has 500 miles of shoreline and it’s maximum depth is 264 feet. Smith lake has small mouth, large mouth and stripe bass as well as catfish, crappie and trout to name a few.  
We also have Bankhead Lake and Walker county Lake which are stocked with a good supply of fish.  These lakes are not as large as Smith Lake, but they have as many benefits and still require a good fish finder to locate the larger fish which stay in the deeper water.   
There are a lot of different brands and types of fish finders on the market these days.  At www.deepwaterfishfinder.com you will find a large selection of fish finders for freshwater fishing and saltwater fishing depending on which type of fishing you prefer.  A few of the brand names are Garmin, Humminbird, Furuno, Lowrance and Interphase to name a few.  They make fish finders with color screen, fish finders without color and fish finders with a gps system included.
I like the Garmin fish finder 160c with dual beam which can be found at www.deepwaterfishfinder.com because it allows me to see the larger fish in the deep as well as shallow water so I can catch my trophy fish. It can detect fish as deep as 900 feet and has an alarm for larger fish.  Its waterproof so I don’t have to worry about keeping it dry and with its color screen I have a better view of what’s underwater.  At Deep Water Fish Finder you can choose the right fish finder for you and have it shipped right to your door.  They ship within days of your order, sometimes on the very day you order.
With the many lakes we have in Walker County such as Smith Lake with it’s water depth of 264 feet and it’s great supply of large mouth bass, small mouth bass and stripe which can weigh as much as 40 pounds and Walker County Lake and Bankhead Lake with their large supply of quality fish, a Garmin fish finder 160c from www.deepwaterfishfinder.com would improve your chances of catching that trophy fish you’ve been dreaming of, because the larger fish stay in the deeper water and a fish finder helps you locate where the fish are so you where to throw your bait.

I’m a 47 year old man who’s married with four children. I love to camp and go fishing with my family. I love to read anything written by James Patterson and Robert Parker. i watch baseball, football and anything pertaining to sports. I have a internet business  www.deepwaterfishfinder.com which sells fish finders and gps system and www.qualitytentsforyou.com which sells tents, sleeping bags and other camping equipment

Those of us who have gone fishing know how tedious and time consuming it can be looking for that all important “bite” on the fishing hook. Fishing can be described as an activity that tests ones patience to the limit. With the new gadgets that are available nowadays fishing no longer needs to be a patience tester. One such product that has changed fishing forever is the kayak fish finder.

A kayak finder is a gadget that will help you find schools of fish in virtually any type of water while you are in your kayak. Once you install a kayak finder, it will eliminate all guess work from your fishing expeditions and lead you to the areas where the fish are situated. Of course this equipment will not make the fish bite the hook, but at least you will know where they are hiding.

So the next question, how does a kayak finder work? The basic concept is simple. It uses sonar technology which is similar to radar, to scan the water and send back the info to a receiver. The receiver will have a digital screen on which one will be able “see” where the fish are swimming. They generally use rechargeable batteries. It can be used in fresh water or salt water, and by serious fishers or beginners.

In this way, kayak fish finders are very versatile and will take ones fishing experience to a whole different level. Like many electronic products, kayak fish finders will vary according to quality and price. Some of the companies that make kayak finders are Hummingbird, Garmin, Eagle and Lawrence.

The capability of the fish finder will depend on the price. The more expensive ones will have a powerful sonar that can handle depths up to 90 feet where as the cheaper models will only be able to scout depths up to 5-10 feet. Some of them will have additional accessories such as thermometers. The more expensive ones will have a large color LCD display and even a global positioning system (GPS) built into it.

This can be useful in areas where one may get lost while kayaking. The GPS can also be used to “mark” a certain spot or area where more fish can be found. Humming bird makes a small portable fish finder the RF 35 that can be worn as a watch and costs around 90 dollars. Some of the more expensive kayak fish finders with GPS capability can cost in excess of 400 dollars.

No matter how much you like to fish locating them can be difficult. This is where a portable fish finder can be helpful. It offers more flexibility than a fixed fish finder has.

Knowing all of the ways that a portable fish finder offers you flexibility will help you see why it is a good idea for any fisherman to have one. Here are some of the top boys anyone using a fish finder will appreciate their flexibility.

1. Always finds the fish – When you are fishing you don’t want to have to wait hours for a small nibble and you definitely don’t want to get no bites at all. because the fish finder is designed to always be able to tell you where the fish are located you won’t have this problem anymore.

This will allow you to only fish in the spots where fish are indicated which gives you the best chance possible of catching fish and enjoying your day in nature.

2. Always dependable and ease of use – Fish finders are easy for anyone to use and they are designed to always work even in the most extreme fishing conditions. In other words if the temperature is nearly zero and the water depth is 99.99 feet deep then the finder will still be able to find fish for you.

Plus these finders will not only tell you where the fish are but they will also let you know if there are any rocks or weed present where fish can hide.

3. Portable – This is the biggest flexibility that is offered because you can easily take it with you if you are going to be one a boat or fishing on ice. With some of the finders they have to be fixed in place and this limits your ways of using them.

With fish finders that are portable you can use them anywhere you want to go fishing and know that they will be reliable and will always find the fish for you so you can enjoy a day of catching fish instead of just waiting around hoping for a bite.

Now that you know the ways that a portable fish finder can offer you flexibility you can see why so many fishermen prefer to use one. If you want to have the best chance of catching fish also then you will definitely get your own fish finder.

His GPS website is the best GPS Store for buying, Garmin GPS Systems, Automotive GPS, GPS Accessories, Marine Electronics, portable fish finder, and Camping Supplies.

If you’re looking for a multi-functional fish-finder to use for offshore fishing around the coastal united states or for fishing inland, then GPS fish finders might be just what you need. GPS fish finders are stuffed with detailed maps of the shore and inland waterways which detail restricted areas, depth contours and present and tide info.

GPS fish finders are a little more expensive when compared to other styles, particularly the transportable fishfinder, but the price could be worthwhile for all of the features it provides.

GPS fish finders like the Garmin GPSmap 440S offer photo mapping with aerial pictures of waterways, marinas and navigation landmarks. This unit uses satellite images for the entire coast of the US including Hawaii, Alaska and the Bahamas.

GPS fish finders can also be used inland on lakes and other waterways. The Garmin GPSmap 530S provides coast to coast maps for the inland waters of the united states. This unit also provides area information for over 5000 of these bodies of water.

By trying inland GPS fish finders, you’ll have details at the tip of your fingers on such information as marina locations, campgrounds, mile markers, ship ramps and depth contours.

GPS fish finders are the best fishfinder to use for fishing in deep waters. They have multiple frequency transducers which let you see fish up to 1500 feet deep.

GPS fish finders also provide real time weather reports which includes weather radar for tracking typhoon cells. This information informs you of wind speeds, water surface temperatures and typhoon forecasts so you’ll always be on top of the weather while you are on your ship.

GPS fish finders have the best displays. The screens are high resolution and can be viewed in sunlight and shade. The Garmin GPSmap 545S has a five inch diagonal display. Some units also provide split screen capacity.

GPS fish finders are on the high end but prices vary significantly for this type of fish finder. You can spend a few hundred dollars or about a thousand. For instance the Lowrance HDS-10 is at the higher end of the price scale. It contains information on over 100,000 bodies of water. It has a 10.4 in. VGA split screen color display.

It can pay to look around when shopping for GPS fish finders. You can find some great deals if you look on the web. You can even buy one used and save even more .

If you don’t own a boat, then GPS fish finders are doubtless not the best fish-finder for you. You may prefer to own a portable fishfinder so you can take it irrespective of what ship you fish from. GPS fish finders are ideal for folk who spend lots of time on their ship in open waters.

GPS fish finders are probably the great fish finder you can buy simply because they have so several features. If you consume plenty of time in your ship, GPS fish finders are very valuable. They’re going to provide you with detailed maps, weather conditions, satellite images, local info and sonar data that may help you in finding the fish.

Many people ask, “How do I select the proper fish finder for my needs?”  There are 5 aspects of a fishfinder to keep in mind when making a purchase.

 

The Transducer

 

There are 2 types of transducers:  single frequency and dual frequency.  Single frequency is generally best for lakes and shallow coastal fishing.  Dual frequency transducers are generally better for deep sea fishing.  Dual beam transducers limit the beam size for the high frequency beam so these fish finders are truly best for deep water.

 

Power

 

In general, the higher the power of your fish finder the better.  Higher powered fish finders generally cost more so you will have to weigh power with cost.  Remember that even in shallow water such as lakes, higher power will still help with better imaging.  Most expert fishermen recommend giving the most weight to the power rating of your unit.

 

Depth

 

A fish finder being able to reach greater depths is directly related to the Power and the quality of the transducer.  In general, the more expensive models penetrate the water better.  Keep in mind while shopping that the depths shown in the product specifications are for clear water.  Salt water and murky water will limit the depths the sonar can penetrate.  As a general rule of thumb, purchase a fish finder with a depth range about 10% greater than what you intend to fish.  Having a slightly greater depth range should help adjust for less than clear water.

 

Display Size

 

Fish finder displays vary from four inches to seven inches (and some larger).  Obviously the larger the screen, the higher the cost.  The advantage to a larger screen can be ease in seeing the results in bright sunlight.

 

Display Resolution

 

The display resolution pertains to how clear the image is on the fish finder screen.  The higher the resolution the better the image will be.  Color screens are often better for direct sunlight as they are easier to see.  Again, the higher the resolution, the higher the cost, in general.

 

Now that we’ve covered the basics of how a fish finder works and what the key pieces of fish finders are, let’s offer some suggestions on how to choose the perfect fish finder for you. 

 

Most fishermen recommend doubling whatever you were planning to spend on your fish finder.  We leave the amount you wish to spend completely up to you.

 

Next decide where are you planning to fish the most often- on a lake, along coastal areas or are you mostly a deep sea fisherman?  Are you planning to use your fish finder on only one boat or do you want to be able to use it on a friend’s boat?  Answering these two questions will let you know if you want a fish finder that works best in shallow or deep water and whether or not you want a fixed mount fish finder or a portable fish finder. 

 

If you want a fixed mount fish finder then you will next need to decide if you want a transom mount transducer or a hull transducer.  Transom mount transducer are easier to install and usually less expensive.  You can purchase a transom mount transducer in single or dual frequency models.  They work best in water that is somewhat calmer and are not terribly effective at much more than 10 knots. 

 

Through hull transducers are the best for clarity and performance, but are harder to install and cost more.  You really need to have a need for high speed bottom reading to make them worth the extra cost. 

 

In general if you are going offshore or into deep fresh water, the hull transducer with dual frequency is probably the best bet for accurate fish readings.

 

If you are using a smaller boat and are not planning to do high speed fish finding then a transom mount or portable fish finder will save you some money and should meet your needs just fine.

Not all fish finders work well in all types of fishing.  If you like to fish in freshwater then you should look for a fish finder that will work best for freshwater fishing.

In general single frequency fish finders are adequate for freshwater fishing.  Single frequency fish finders work well in most lakes, rivers and in shallow coastal fishing and they are generally less expensive.  Single frequency fish finders have less depth penetration than dual frequency models, but for freshwater that is generally acceptable.  Most freshwater fishing is not in deep water so being able to see to depths of 1000 feet or more is not needed.  The single frequency fish finders will often have a larger cone angle which will let you see a broader area at a more shallow depth.

If you happen to fish in the Great Lakes or other very deep lakes or rivers then a dual frequency fish finder will serve you better.  The dual frequency settings will allow you greater visibility at deeper depth and overall deeper depth penetration. 

Another aspect of freshwater fishing to consider when choosing a fish finder is what type of craft you use for fishing.  Many people use kayaks, float tubes, canoes or small boats when fishing in freshwater.  If you use one of these smaller crafts you should consider a portable fish finder.  Both Eagle and Humminbird make portable fish finders that are both affordable and an excellent choice for shallow freshwater. 

For very shallow water, two to ten feet, one of the best choices is the Humminbird Fishin Buddy line.  These fishfinders are portable and also have side viewing capability which allows you to see fish off to the side of your boat.  Plus you can adjust the shaft on these models to see at different depths.  There are several different models in this line and they are all inexpensive.  If you prefer fixed mounted fish finders, the Fishin Buddy line can also be mounted to your craft using the included bracket.

The Eagle portable fish finders are also a good option for people who fish from small crafts or from multiple boats.  These portable fish finders generally have suction cup mounting systems and are quite versatile.  In general the Eagle portable fish finders are also extremely affordable and definitely offer a good value for your dollar.

If you are selecting a fish finder for freshwater fishing, consider the water depth and type of craft you usually use.  Unless you are fishing in truly deep water, like the Great Lakes, you can often get great results from some of the more inexpensive models.  If you are in the market for your first fish finder then you may want to start with a simpler model and trade up to the more advanced models as you gain experience with finding fish easily.
