Here’s a useful tip for judging the width / thickness of a sonar return: switch on the vertical flasher (also know as a-scope) on your fish finder if it has one (to do this on the Deeper App, go to Settings > Sonar > Vertical Flasher). The vertical flasher on the right side of your screen will show you exactly what’s under your sonar at this exact moment. You can use it for vertical jigging, and of course forice fishingtoo. For judging fish size, look at both the thickness and width of the returns on your vertical flasher. A larger fish will give both a wider and a thicker return.
A fish finder is a sonar instrument that is designed for the specific purpose of detecting fish underwater. It does so by detecting reflected impulses of sounds energy. All the electronic impulses that are reflected off fish are converted into information that is then display in graphic rendition on the screen of the fish finder. In addition to locating fish, these units also measure the depth of the water, locating underwater debris, and bottom structure. The image on the screen of the fish finder can represent just one fish in the form of a small icon or with a series of arches.

When choosing the fish finder, you also need to choose the unit with the right frequency, which is also an important feature of the transducer. The frequency is directly related to angle of the cone. On most of the transducers you can find the following frequencies: 50, 83, 192 and 200 kHz. A higher frequency will give you more detail on the screen. You can find models that offer dual, single and multiple frequencies.
Fully Networkable, 8” Touchscreen Chartplotter and Sonar. Garmin’s GPSMAP 7608xsv includes built in maps for Coastal and Lake mapping, a 10HZ GPS Receiver providing fast acquisition and position tracking. High Performance HD-ID Sonar, 1kW CHIRP, CHIRP DownVu and CHIRP SideVu. Now enjoy FLIR Camera Compatibility, Smart Boundaries and More. Transducer Required and Sold Separately.
A GPS also gives you navigation through the waters. For this you will need to select a unit that comes with background maps and charts. One more benefit of the addition of the GPS is safety. Wherever you fish, you will have the confidence that at the end of the day the GPS will easily point you home. For example, you could be fishing throughout different locations during the day, or you could lose sight of land, or some severe weather could suddenly roll out. In such situations, a GPS will give you the exact direction to your home and will tell you how far it is.
Raymarine has a few units that come with a built in GPS. The Dragonfly 4Pro, Dragonfly 5Pro, and Dragonfly 7Pro all have built in GPS. Pay close attention to the unit you are buying, because if you are looking for built in GPS the standard Dragonfly 4 and Dragonfly 5DVS do not have that feature built in. You absolutely have to go Pro to make sure you get the GPS you’re looking for.
Although this unit lacks some of the features found in similar units from different manufacturers, it counterbalances with powerful sonar, using CHIRP for both down view and classic imaging. Additionally, it also comes with Wi-Fi connectivity, and you can benefit from a larger view if linked to a bigger tablet. It's a unit with a tremendous quality and price ratio, with a rating of four and five stars.
Fishfinders operate using a single frequency transducer, dual frequencies, multiple frequencies or a broadband CHIRP system. In general, higher frequencies give the finest detail resolution, the least background noise on your screen and the best view from a fast-moving boat, but don’t penetrate as deeply as lower frequencies. Shallow-water inland anglers generally choose higher frequencies of 200kHz, 400kHz or 800kHz. For maximum depth, use lower frequencies. We recommend 200kHz or higher (up to 800kHz) for water depths up to 200' and 80kHz or 50kHz for deeper waters.
The best value fish finder models that we have listed above are the most popular in 2014. All of them have high fish finder ratings and predominantly positive reviews of the users. According to your needs, one model or other might be a better choice for you. When you compare fish finders, you should consider your budget and the features you would like the fish finder you are looking for to have. Before choosing fish finder, you need to decide do you need a portable unit or a fixed one for mounting onto your boat. Also consider will a fish finder be sufficient for your needs or do you also need an integral GPS in the unit. We hope that with the information that I have provided in this best fish finder reviews, you will find a fish finder that will help you catch more fish.
To get the most of the both there’s the dual beam type of transducers. It’s also called dual frequency and which combines both features in one unit. Other types of transducers are more specialized. They include multiple beams (can be 4 or more). These cover a larger area of the underwater and can even give a 3D image on the display. One more option is the side beam transducer. These units shoot their signals to the sides, which increases the search area for fish.
The depth scale on the right of the screen enables you to identify the depth of any features you find. The depth reading in the top right of the screen shows you the bottom depth under your fish finder right now – bear in mind this is not necessarily the same depth as the features you have just scanned, especially if you are scanning drop offs or points.
Higher frequency transducers have shorter wavelengths and more wave cycles per second, which means you can visualize more details (smaller fish) but have only shallow to moderate depth capacity. One sound wave at 200kHz is slightly longer than 1/4", so a 200kHz sound wave will be able to detect fish as short as a quarter of an inch. A 200kHz transducer has a range of only about 600'. High frequency provides a crisp, clear picture of the bottom with the tradeoff of less depth range. For best resolution, choose 800kHz or 455kHz transducers.
KISS (the hottest band in the land): OK, maybe this won't be covered in my book, so I can talk about it now. I still can't believe that Madonna is in the Rock And Roll Hall of Fame, and Kiss is not. Kiss hasn't sold more albums than Madonna - not even close. Kiss hasn't collected more gold albums than Madonna - not even close. I guess Gene Simmons' "Family Jewels" really doesn't factor in to the overall calculations. Correct me if I'm wrong, but I don't think Madonna has ever used the words "rock and roll" in the lyrics of a song. Kiss, on the other hand has almost abused the phrase. But then, that's what a rock and roll band is likely to do.
Few things aggravate ice anglers more than frozen rod guides. Chipping away with fingernails, teeth, or anything else lying around can easily damage both the frame and rings of the guides, but you have to keep them clear because iced guides will weaken line, especially super-­light monofilament or fluorocarbon. There are a number of homebrew remedies for tackling this problem, but none are more effective than lip balm, which creates a film on guides that inhibits them from freezing and building ice. It’s waterproof and takes quite a while for wet line or precipitation to break it down and necessitate reapplication. A small stick or tin stores easily in your pocket, and just a few swipes with your finger on guide rings will protect them from ice-up for several hours.
LCD displays are made of a grid of “picture elements,” tiny dots that individually darken when electrical current is applied, with their name shortened in common usage to “pixel.” More vertical pixels mean higher depth resolution, as each pixel represents less depth. The number of pixels in a screen’s horizontal axis determines how long objects stay onscreen before they scroll out of view, of significant importance with split-screen displays showing narrow columns of side-by-side information.
In summer and winter, water temperature is very important - these units will help you discover areas that should be comfortable for your target species. Safety is found in structure, for prey and predator alike. The illusion of safety for baitfish equates to food for prey. So locating proper structure is certainly important. It's been said that 90% of the fish can be found in 10% of the water. Believe it. If you're fishing structure in the middle of a lake or a man-made reef, knowing what's below you is important. Now you know.

Important parameters of a fishing line are its breaking strength and its diameter (thicker, sturdier lines are more visible to fish). Factors that may determine what line an angler chooses for a given fishing environment include breaking strength, diameter,castability, buoyancy, stretch, color, knot strength, UV resistance, limpness, abrasion resistance, and visibility.
