The standard duel beam wide and narrow scan transducer issued with the unit provides enhanced performance with the duel scan feature of the Garmin 140 fish finder particularly useful when used in shallow water. Mounting the transducer is a cinch and can be installed to a number of places including inside the hull, on the transom or even on a trolling motor but care needs to be taken to ensure that it remains below water level while planing so that air bubbles don't adversely effect the information.

Both wide and narrow beams are used by the duel beam transducer giving the unit more tractability and are governed by the width of transmitted sonar beam and by the depth of water in which its being used. The narrow beam can be of selected use while working in deep water and gives clear displays when at its maximum width For example, the narrow beam would cover an field of around a seven feet circle at a water depth of about 30 feet.

Optimum usage of the wide beam feature of the Garmin 140 is while fishing in shallow water as it supplies the user images of what is around the boat particularly near to the surface. While working in a thirty foot depth, a braod beam would cover an area of that of an approximate 20 feet circle and also displays crisp precise images of objects in the water more close to the surface.

Offering the user very clear images of what's around and under the boat, the Garmin 140 Fish Finder also displays images of the bottom.

The display is enhanced by a back light for night-fishing and can be manually adjusted to suit conditions or turned off completely to extend battery life.

The Garmin 140 also provides the option to be able to save the settings after its shut down giving the user the alternative of being able to find a favorite fishing spot again.

The ultra scroll feature allows refreshing at lightening speed providing accurate up to up-to-date data. Setting the gain to automatic or manual alteration is another characteristic allowing users to control the clarity of images displayed.

Other Garmin Fish Finder 140 features include:

* Range change Auto rescaling

* Improved See Through Technology allowing weak and strong digital signals.

The white line feature allows the user to check on the depth of the bottom underneath the boat.

* 4X and 2X Manual and Auto zoom providing individual user mastery.

* Featured alarms for shallow and deep water, fish and fish size alarm,

A further feature of the Garmin 140 Fishfinder is the low battery level blinker.

The complete package has all you need to successfully attach and use the Garmin 140 fish finder GPS combo and comes with a precise and comprehensive user friendly owners manual containing how to install and use the unit to it's maximum potential.

Portable Fish Finder - Why Use One?

I have enjoyed the hobby of fishing for many years now and have seen the technology in fishing equipment go from the simple fibreglass fishing rod, single speed reels and nylon line to lightweight carbon fibre rods, magnetic controlled 3 speed reels and lines so fine yet strong enough to lift an elephant if you wanted to.

Perhaps the most distinct advancement in the tackle box is the development of the portable and GPS fish finder. There are of course a whole range on the market, some with functions straight out of a bond movie. But which type is better than the other?

The best portable fish finder advantages are:

Location - Obviously as the name suggests these units can be taken with you and used in an array of locations. Whether you are on holidays or just enjoying your regular weekend session, fishing from land based locations, from a boat or any other type of water craft, do not present a challenge. Flexibility - Portable fish finders will usually have a castable transducer. For tricky fishing locations where it is difficult to manoeuvre your watercraft, cast the transducer exactly where you need it and it will give you a good idea of structure and whether there are fish to target. Stealth - The castable transducer can also give you the competitive edge of stealth. Placing the transducer over your preferred fishing spot without having to manoeuvre your noisy boat will avoid spooking your target. Specialty fishing - Specialty fishing like ice fishing can also benefit from sonar technology of a portable fish finder. Some units are designed to take extreme cold. Just drop your transducer in and away you go.

When buying a portable fish finder consider the following:

Transducer - If you intend to fish in lakes and shallow water use a single frequency transducer. For open ocean or deeper situations a dual frequency or beam is a better choice. Resolution - Get the highest resolution you can afford in color. Indoors the difference in resolution isn't apparent. In the field the higher resolution screens will definitely make your fishing experience a good one. Screen size - As with resolution, bigger the better. Especially for open ocean situations where you need to use split screen functions. Power - Portable fish finders do struggle when it comes to power supply. If you cannot afford a unit with good power endurance consider purchasing a unit with a removable battery. Buy a second back up battery for when that moment hits. Don't forget to pack the second battery. Signal strength - Essentially the better quality units will have a better signal strength however, consider how diversified your intended fishing will be. If you are only going to fish in shallow water locations signal strength is not such a concern.

Portable fish finders have definitely given land based anglers the same competitive edge ocean based anglers have enjoyed for many years.

For me, the greatest benefit of a portable fish finder is being able to pack it in your bag, go on holiday and explore new fishing spots. Casting the transducer and assessing potential spots quickly ensures my limited time is used effectively.

How to Use a Portable Fishfinder

Portable fishfinders are increasing in popularity. This fact is mainly due to their perfect fit for recreational fishing. Since they are relatively inexpensive and, of course, portable, they are a perfect out-of-the-box solution for many weekend warriors.

Once you actually purchase a portable fish finder, how do you use it? That is overall a simple question to answer. First, the manuals are generally excellent and for the most part simple to follow, so read the manual! After that, here are some simple steps to follow to help increase your enjoyment during your next fishing trip.

The Power Supply- Most portable fish finders are powered by batteries, generally AA batteries. Make sure when you are purchasing your unit you are aware of what type of batteries are needed. It is advisable to buy re-chargeable batteries as even if the unit has a long battery life you will need to re-charge the batteries after several long fishing trips. Using re-chargeable batteries will greatly reduce your expenses in the long run. Mounting- How do you mount your fish finder? The answer to this question will depend on the type of fishfinder you are using. Some fishfinders have a suction cup mounting system for the transducer. You can mount these transducers anywhere on your boat as long as they are securely attached and also underwater. If the sonar is not underwater, you will not find any fish! If you mount the fish finder on a boat make sure it is not too close to the motor or else the motor wash will interfere with the sonar readings. The Humminbird Fishin' Buddy fish finders come with a "mounting clamp" which will allow you to attach the fishfinder to the side of a boat or to a low dock. Lastly, if you have a wireless fish finder you can generally attach the sonar unit to the line and cast it with your lure. Speed- It is not recommended to use your portable fishfinder at high speeds. In general, high speeds will stress the unit and possibly break it. At high speeds it is best to pull it out of the water and then put it back in while moving at about 1-2 mph to help you scan the bottom of the water. The Display- Since most portable fishfinders are not as effective at great depths, they are used mostly in shallow freshwater. They can be used in shallow saltwater as well, but that is not as common. So what do you look for on the fishfinder screen? Look for depth, water temperature and bottom structures. Look for drop offs, weed beds, rocks, fallen logs, sand, mud and any sort of transitions. These are areas where fish like to hide.

Now that you have some simple ways to increase your fishing enjoyment using your portable fishfinder, let's quickly answer the question of why you should use one. First, portable fishfinders can go with you on any fishing trip. They can be used on your boat, your buddy's boat or even from a land location. Second, portable fishfinders can let you adapt to fish behavior. The wireless fishfinders allow you to cast your transducer with the lure in "stealth" mode thereby not spooking the fish. Lastly, portable fishfinders are very versatile. There are even ice fishing models that can handle the extreme cold. Overall portable fishfinders have brought to recreational fishing what professional fishing has had for years-the ability to find fish quicker so that your true fishing skills are brought to bear.
