The image above, at right, clearly shows the bottom structure—plants, sediments and hard bottom are discernible on sonar plots of sufficiently high power and appropriate frequency. Slightly more than halfway up from the bottom to the left of the screen centre and about a third away from the left side, this image is also displaying a fish – a light spot just to the right of a 'glare' splash from the camera's flashbulb. The X-axis of the image represents time, oldest (and behind the soundhead) to the left, most recent bottom (and current location) on the right; thus the fish is now well behind the transducer, and the vessel is now passing over a dip in the ocean floor or has just left it behind. The resulting distortion depends on both the speed of the vessel and how often the image is updated by the echo sounder.

For those who want the ultimate in fish finding technology, we have the Lowrance HDS-9 as a top rated fish finder. Not only do you get a large screen, but it’s touch activated for even more convenience. It’s so wide that you can chart two maps at once, and it’s all high-definition which allows you to create 3D models of the bottom of any lake or river in real time. Overall, this is as good as it gets.

Portable fish finders are the better choice for those who lease their boat. Also if you ice fish or “fly-in” fish, a portable unit would be more suitable for you. They usually come with their own carrying case and battery power supply. Most of the fish locators come with the transom mount for installation. The portable units come with the transducer already attached to the transom with the use of a suction cup.

Modern lines are made from artificial substances, including nylon, polyethylene, dacron and dyneema. The most common type is monofilament made of a single strand. Anglers often use monofilament because of its buoyant characteristics and its ability to stretch under load. Recently alternatives such as fluorocarbon, which is the least visible type, and braided fishing line, also known as 'superlines' because of their small diameter, minimal amount of stretch, and great strength relative to standard nylon monofilament lines.

A fishing rod is an additional tool used with the hook, line and sinker. A length of fishing line is attached to a long, flexible rod or pole: one end terminates with the hook for catching the fish. Early fishing rods are depicted on inscriptions in ancient Egypt, China, Greece and Rome. In Medieval England they were called angles (hence the term angling). As they evolved they were made from materials such as split Tonkin bamboo, Calcutta reed, or ash wood, which were light, tough, and pliable. The butts were frequently made of maple. Handles and grips were made of cork, wood, or wrapped cane. Guides were simple wire loops.

NO INSTALLATION REQUIRED: That got your attention, didn't it? If you're on a budget, and don't want any sort of permanent installation mods to your boat, the Humminbird Smartcast series may be your answer. You simply cast the green transducer to the spot where you want to investigate, and the signal comes back to the wrist module (RF30) or the traditional display model (RF15). This series doesn't have a lot of bells and whistles, but for my kind of fishing/paddlecraft, it may be a great solution.
Fish finders were derived from fathometers, active sonar instruments used for navigation and safety to determine the depth of water.[1] The fathom is a unit of water depth, from which the instrument gets its name. The fathometer is an echo sounding system for measurement of water depth. A fathometer will display water depth and can make an automatic permanent record of measurements. Since both fathometers and fishfinders work the same way, and use similar frequencies and can detect both the bottom and fish, the instruments have merged.[2]
Spend more time catching fish and less time trying to find where they are hiding with the Helix 7 CHIRP GPS G2 Fish finder. Using side-by-side dual imaging technology, this fish finder not only lets you map structures and schools, but also allows you to view both CHIRP Down Imaging and Switchfire Sonar data at the same time, providing the most complete image of the underwater environment possible. In addition to the large 16-bit display, the Helix 7 also features an integrated GPS that store up to 2500 waypoints and 50 routes so you can mark the coordinates of all the best fishing spots on your favorite lakes and rivers.
The power of a fishfinder—the strength of the “ping”—is expressed in watts RMS (root mean squared). Power is directly related to how well you see in silt-laden water, view down to greater depths, and successfully resolve separate targets and bottom structure. A 500-watt (RMS) fishfinder should have plenty of power for most coastal applications. Serious bluewater anglers should look for 1,000 watts or more. Inland lake fishermen can see the shallow bottom with only 200 watts.
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 an incredible tool that can help take your sport or commercial fishing venture to the next level. However, even the best fish finders can use a little improvement – and adding a GPS is one way to do this.The best fishfinder GPS combo will help you navigate whatever body of water you are on at the same time as it allows you to find where to fish more quickly, accurately and efficiently.

Whether you're off to a nearby stream for some fly fishing or heading out into the open waters for a deep sea fishing adventure, the right fishing gear will make your trip even more exciting. When the weather's nice, find a quiet spot to cast your line with a new fishing reel. Pick up a rod and reel combo that's ready to go right out of the box or customize your fishing gear with a separate rod and reel.

The image to the right shows a school of white bass aggressively feeding on a school of threadfin shad. Note the school of baitfish near the bottom. When threatened, baitfish form a tightly packed school, as the individuals seek safety in the center of the school. This typically looks like an irregularly shaped ball or thumbprint on the fishfinder screen. When no predators are nearby, a school of baitfish frequently appears as a thin horizontal line across the screen, at the depth where the temperature and oxygen levels are optimal. The nearly-vertical lines near the right edge of the screen show the path of fishing lures falling to the bottom.

ONE SMALL STEP FOR MAN, ONE GIANT LEAP FOR PADDLING_KIND: In the 2009 ICAST article, I mentioned a combo system that was in the new products exhibit, but wasn't available at the time of the show. It's most certainly available now, and that unit is the Humminbird 385CI. Like us, fish seek comfort, safety, and food. This unit will allow you to gather "data" that you can process in to fish finding "information".
Another great feature of the Elite-5X HDI is the Downscan Overlay that combines traditional sonar with Downscan. Downscan’s primary purpose is finding structure, but it can’t very accurately spot individual fish. That is better done by sonar. Combining the two in one, this device displays on one screen both bottom and structure. So you can see every rock and submerged object as well as fish.

The display is all about pixels. With more pixels you will be able to see more details, so it’s also an important factor to consider. More pixels also means higher price of the fish detector. We would suggest going minimum 240(v) x 160(h) pixels of the screen. However, this screen will give a pretty blocky image. To have a sharper image and better resolution, you will need to invest more.
It terms of the functionality, the HDS-7 is able to connect to the internet to broadcast data, update to new software, upload information such as marked coordinates and more. This Lowrance model uses the latest of advanced technologies such as CHIRP sonar, Broadband sounder, StructureScan HD, DownScan imaging and Trackback view for the ultimate fish finding experience.

Fish finders are incredibly valuable tools, and the more you learn about how to read them, the more successful your fishing trips will be. A key part of learning as angler is to go from trial and error to a more knowledge-based approach. Maybe you regularly catch at a certain spot with a certain presentation – but do you know why? A fish finder will help you understand not just your failures, but also your successes. And once you know this, you can recreate this success more easily.
The term tackle, with the meaning "apparatus for fishing", has been in use from 1398 AD.[1] Fishing tackle is also called fishing gear. However the term fishing gear is more usually used in the context of commercial fishing, whereas fishing tackle is more often used in the context of recreational fishing. This article covers equipment used by recreational anglers.
