Echo Sounder / FishFinder

An echo sounder is one of the many types of equipment used for marine navigation. This device is used to measure water depth by transmitting acoustic waves downward into the water by a transducer, which will be reflected from the bed as an echo. The time interval between the emission of the sound pulse and its return, along with the speed of sound in water, are then used to calculate the depth of the water.

In situations where the ship doesn’t have accurate data on its position, an echo sounder allows one to determine the under-keel clearance and depth of water – critical information, especially when approaching a port, crossing over a bar, nearing the mouth of a river, or navigating a poorly surveyed area. Aside from determining the depth of the water, this device also doubles as a fish finder – it provides accurate identification of fish.

Choosing an Echo Sounder

There are a few features that make for an excellent echo sounder. When shopping for your new fish-finding weaponry, here are some basic characteristics to look out for:

Resolution Revolution

The resolution comes with several aspects to look out for. You may want to consider one with a high vertical pixel count as it offers better resolution. Be sure to also look out for one a big screen with good backlighting and view-ability.

Transducers

Arguably the most important feature of an echo sounder, transducers transmit and receive the signal. Be sure to consider the transducer’s power, type, and location, as it can make a whole world of difference in terms of accuracy and usefulness. The Active Imaging 3-in-1 Nosecone Transducer for Ghost Trolling Motor, for instance, offers powerful fish-finding capability and high-resolution images of structure and cover below and to the sides of the ship.

Grey and Colour Line

The Grey Line and Colour Line refer to a function that gives anglers a refined definition of objects and fish close to or right on the bottom.

Bottom Lock

The bottom lock function displays the bottom as a straight line while displaying targets, such as vegetation and fish, above the bottom.
