Fishing boat electronics cover wide range of electronic devices. Some of them increase the chance for successful fishing, but many people neglect their importance. Some of these devices are mandatory for very good reasons and it is vital to know how and when to use them.
Fish finders use ultrasonic sound to detect obstacles that are in the path of sound beams. These 'obstacles' can be individual fish, schools of fish, seabed, divers etc.
Fish finders display depth of the water, bottom configuration, fish position, underwater activity and have many features that determine their price - from few tens of dollars/euros to thousands of dollars/euros. Since this equipment can cost a lot, be sure to know what is what you need - if you need few basic functions, then what is the purpose in spending money on multi-beam sonar that comes with integrated maps, GPS, navigation, bluetooth/USB/wireless connection with computer etc.?
But, in many cases, fish finder like that is going to make difference between having a great day and coming home empty handed ...
Global Positioning System (GPS) is very important part of successful fishing trips away from the shore. Even if fishing close to the shore, it can be very important to find 'exact' position - within few feet/meters.
And if you have GPS/Sonar/Fish Finder/Chart Display combo, then you have very nice piece of equipment that can be very very useful ....
Widespread usage of cellular phones didn't diminish importance of good radio on boat or during coastal fishing trips.
Functions like dual-watch, tri-watch, priority scans, weather alert function, waterproof design etc are common these days, so don't go cheap on this - good radio is like a good anchor - you will not appreciate them until you really need them :o)
Of course, there are many other electronic devices which can or must be found on the fishing boats, regardless of the size and/or type.
