A fishfinder or sounder (Australia) is an instrument used to locate fish underwater by detecting reflected pulses of sound energy, as in sonar. A modern fishfinder displays measurements of reflected sound on a graphical display, allowing an operator to interpret information to locate schools of fish, underwater debris, and the bottom of body of water. Fishfinder instruments are used both by sport and commercial fishermen. Modern electronics allows a high degree of integration between the fishfinder system, marine radar, compass and GPS navigation systems.
BABY STEPS: You don't have to spend a ton of money or be an engineer to get your kayak electrified. Here we have the Lowrance X50DS. The fishfinder and the installation kit will run around $250. Look at what you spend for a rod/reel/braided line, and you'll find this kit is certainly affordable. The display is 4-level grayscale, and the battery pack contains AA batteries. However, what it may lack in fashion it makes up by function. The battery pack goes in a dry bag, and the unit itself is easily removed at the end of the day. It features a built in temperature sensor and 120 degrees of wide angle coverage.
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.
Higher frequencies, such as 192 or 200, are ideal for fishing in shallow water. Lower frequencies, such as 50 or 83, are perfect for deep water fishing. To find the top fish finder for the money, knowing what area you’re planning on using it in will lead to more catches. Remember that the higher the frequency, the more detail you’ll have on the screen.
As we mentioned, the strength of a fish finder is in how well it can locate the fish, which is why you need a high-quality transducer. CHIRP technology is one of the best you can find, and it provides a 200-watt RMS signal that can reach down to 1,600 feet in fresh water and 750 feet in salt water. Overall, you can find plenty of fish with this device.
Early sporting fathometers for recreational boating used a rotating light at the edge of a circle which flashed in sync with the received echo, which in turn corresponded to depth. These also gave a small flickering flash for echos off of fish. Like today's low-end digital fathometers, they kept no record of the depth over time and provided no information about bottom structure. They had poor accuracy, especially in rough water, and were hard to read in bright light. Despite the limitations, they were still usable for rough estimates of depth, such as for verifying that the boat had not drifted into an unsafe area.
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.
Fly fishing tackle is equipment used by, and often specialised for use by fly anglers. Fly fishing tackle includes fly lines designed for easy casting, specialised fly reels designed to hold a fly line and supply drag if required for landing heavy or fast fish, specialised fly rods designed to cast fly lines and artificial flies, terminal tackle including artificial flies, and other accessories including fly boxes used to store and carry artificial flies.
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.
