The size of the area you’re scanning will be affected by the angle of the cone. A wide beam cone scans between 40°-60°, meaning you’ll be covering a large area. A narrow cone will scan between 10°-20°. So make sure you’re aware of whether your fish finder is using a wide or narrow cone when you’re looking at the data on your screen. The Deeper PRO and PRO+ have wide and narrow beam scanning (55° and 15°), the Deeper START has a medium/wide beam (40°). One other point to remember about how you sonar works is that it is constantly sending and receiving data, which means your display will be continually scrolling. The current scanning data will be on the right – the further left on the screen, the older the data.

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.
Hockey tape was made for the ice, and even though hard-water anglers are looking for a different kind of score, they should always have a roll on hand. A few wraps around the butt and foregrip of any jigging rod immediately improves the hold and comfort, but hockey tape can be used on any ice tool. If you’ve ever had the cheap rubber handle cover disappear from your ice scooper, you know the feeling of metal freezing to a glove or the burning sting of touching it with your bare hand. A few wraps of hockey tape can easily fix that. Should your bibs or jacket get hooked or ripped, the hockey tape will keep a tear from getting worse until you can make a permanent repair.
Fishing traps are culturally almost universal and seem to have been independently invented many times. There are essentially two types of trap, a permanent or semi-permanent structure placed in a river or tidal area and pot-traps that are baited to attract prey and periodically lifted. They might have the form of a fishing weir or a lobster trap. A typical trap can have a frame of thick steel wire in the shape of a heart, with chicken wire stretched around it. The mesh wraps around the frame and then tapers into the inside of the trap. When a fish swims inside through this opening, it cannot get out, as the chicken wire opening bends back into its original narrowness. In earlier times, traps were constructed of wood and fibre.

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.
A fishing line is a cord used or made for fishing. The earliest fishing lines were made from leaves or plant stalk (Parker 2002). Later lines were constructed from horse hair or silk thread, with catgut leaders. From the 1850s, modern industrial machinery was employed to fashion fishing lines in quantity. Most of these lines were made from linen or silk, and more rarely cotton.[3]
Transducers: 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, 455kHz 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.

Eventually, CRTs were married with a fathometer for commercial fishing and the fishfinder was born. With the advent of large LCD arrays, the high power requirements of a CRT gave way to the LCD in the early 1990s and fishfinding fathometers reached the sporting markets. Nowadays, many fishfinders available for hobby fishers have color LCD screens, built-in GPS, charting capabilities, and come bundled with transducers.[5] Today, sporting fishfinders lack only the permanent record of the big ship navigational fathometer, and that is available in high end units that can use the ubiquitous computer to store that record as well.

If you’ve used a fish finder before, then you might be wondering why it’s necessary to get one with a GPS. To be perfectly honest, if you are someone who likes to fish in your local area and either casts from the shore or the back of a small boat, then GPS capability may not be something that’s worthwhile. However, for any fisherman who likes to go searching for the best catch, having GPS installed on your finder can make a world of difference. Here are some of the best reasons to get the  best GPS combo fish locator.
