Choosing A Portable Fish Finder

Choosing A Portable Fish Finder: The echo sounder or fish finder plays a vital part in fishing today, whether you fish for sport or for a living. This piece of marine technology allows fisherman to target their efforts and improve the volume of their catches. There are a variety of electronic fishing guides on the market, each with their own pros and cons, and each suited to certain environments and uses. In this article, we’ll help you choose a portable fish finder designed with your needs in mind.

Portable Fish Finders

Portable fish finders are an incredible piece of equipment that can actually help you find fish if used properly. Before the invention of this piece of technology, fishers used a depth finder that only indicated the depth underneath the boat. There was no precise screen showing the presence of schools of fish. Consequently, depth finders were of little use to commercial fisherman. Next, there were the sounders with printed graphs rolls that were very accurate if used properly. However, the real breakthrough was the advent of the LCD (liquid crystal display) sounder that showed both bottom contours and fish. Today there is a wide variety of these LCD fish finders.

Picking the right portable fish finder can be difficult because the market pricing is very competitive and products are being updated all the time… The technology has come a long way since electronic fish finders first appeared on the market. Modern fish finders are slimmer, lighter and more menu-driven than their predecessors. The display units have both black and white or color display screens and the screens come in a variety of sizes. The bigger screens are better suited to larger fishing boats where they can be kept out of the sun and weather. These are ideal for commercial fishing trawlers.

A portable fish finder is a dependant on its transducer housing. This housing contains a man-made crystal called a piezoelectric device. When it receives a signal from the unit it converts it into a mechanical sound wave that is sent down to the bottom below the boat. When this wave encounters an object it rebounds – creating an echo. This echo is bounced from the bottom and back to the transducer, where it’s decoded and sent to the display unit as incoming signals. These sound waves not only bounce from the bottom but from any object encountered between the transducer and the bottom. This includes fish, schools of bait, weeds and underwater structures. This sounding process is continuous, even when the boat is moving. As the moving sound wave travels forward, the signals of everything it encounters are sent back as amazingly clear pictures.

Final Note

The effectiveness of your portable fish finder will be contingent on correct mounting. Most units come with detailed instructions but if you don’t feel comfortable doing it yourself, then don’t hesitate to get some help. The actual fitting is quite a simple operation and only requires an electric drill and few basic tools. Problems with fish finders normally can be traced directly back to the wrong type of transducer, or simply poor installation. If you aren’t sure what model to buy or how much money to spend, speak to companies that supply fishing gear and get their advice. They’ll be able to help you choose the right piece of equipment for you.
