Fish finders,depth sounders, Sonars, doesn’t matter what you call them, they’ve come a long ways from the original paper graph of the 70’s. However they still perform the same function: to help you locate fish and see beyond the surface of water, without them we’d still be in the dark ages, but how does all of this work.
Well in simple terms, a signal is transmitted down through the water via a transducer and when that sound wave hits an object that has more density than the surrounding water like a fish, fallen tree, weed bed, and of course bottom, it bounces back, processed and is displayed as an image on the unit’s screen. Throughout the years this image has gotten clearer and clearer.
Today with the advent of new breakthrough features like Chirp technology, Down View, Side View, HD-ID and so on, recognizing fish and fish holding structure is a breeze. Detailed bottom contours, suspended fish and even thermoclines are that much more accurate, detailed and distinguishable.
But do you really need to know how all this modern technology works? Not really, but rest assured that every bit of Chirp, HD-ID, Down vu and Side vu will help you put fish in the boat.
The question shouldn’t be ” do I need a Fish Finder to become a better angler, the question should be, “since I already have one on the console… shouldn’t I be putting another one on the bow?”
