GPS, Fish Finder, Sonar & Transducer Specialists
Fish Finder is an instrument used to locate fish underwater by detecting reflected pulses of sound energy, as in sonar. It can tell you how many fish are out there and their size. It can also tell you a lot about the spot where you are fishing, it determines the depth of the water and temperature.
A GPS on a boat is the main navigation tool for voyage preparation, safe passage and fishing or landmark spot locating. GPS’s units are very accurate nowadays with less than 1-metre accuracy common in most models.
In these modern times of technology, it is rare to find a “stand alone” GPS display or head unit.
Most of the GPS models on the market in all brands are combination units or colloquially called “Combos”. This means they have a GPS, Radar and fish finder all in one unit (along with many other features and variations of sounders/structure scanners etc.)
Many boaters like the functionality of a combo, however, prefer to have a dedicated fish finder when on the water so they can easily see what is going on the fishfinder or tune the sounder without swapping screens or Apps on the combo.
GPS system is the one thing that can ensure when you head home from the sea that you are heading the best and safest direction. Choose your GPS wisely and don’t skimp on this life-preserving boating system. Ask our team for any advice
A transducer is a sensor for the fish finder. It is an ultrasonic transmitter and receiver in one. This is a very sensitive component that can give a good or poor signal to the fish finder if it is selected for the fishing type/hull and installed professionally.
It is the Transducer that changes electrical pulses into sound waves or acoustic energy and back again.
How does it work?
The transducer receives the echoes and the echosounder is able to recognize these differences. The echosounder, then, displays it as a fish.
Can Fish hear my transducer?
No, the sound waves are ultrasonic. They are above (ultra) the sound (sonic) that human ears are able to hear. Humans can hear sound waves from 10 Hz to 20 kHz. Most fish are unable to hear frequencies higher than about 500 Hz to 1 kHz.
The ultrasonic sound waves sent out by Airmar transducers have frequencies ranging from 10,000 kHz to 2 Megahertz (200,000,000 Hz), clearly beyond the hearing of fish. However, most people can hear the transmit pulses of our 10 kHz transducers; they sound like a series of clicks.
