When we talk about nautical electronics, there are two terms that stand out: fish finder and plotter/multifunction display. Although both are assembled on a similar screen, their function and usefulness differ substantially.

What is a fishing probe?

A fish finder or echo sounder is a device that emits ultrasonic waves under the boat to measure the distance to the seabed, interpret its structure, and detect the presence of fish or underwater obstacles. Garmin is undoubtedly at the forefront of this type of device. All Garmin STRIKER models feature built-in GPS, Quickdraw™ functionality, and allow you to mark waypoints and objects for easy viewing so you can return to your favorite fishing spots. Devices such as the Garmin Striker Vivid 7cv offer an optimal experience, as they incorporate traditional CHIRP sonar and high-contrast ClearVü, ideal for enthusiasts and fishermen who need to see precisely what is happening under the boat.

Without a doubt, the brand Garmin represents the cutting edge in this type of devices. All models STRIKER Garmin have built-in GPS, the function Quickdraw™ and allow you to mark waypoints and objects to easily see them so you can return to the places of fishing favorite.

What is a plotter (or multifunction)?

A plotter, also called multiherramienta or multi-function display, integrates functions such as GPS mapping, path of paths, coastal navigation and visualization of navigation charts. Its core is the digital mapping, offering guidance and accuracy on sea routes. With the mapping right, allows you to mark waypoints (points of interest), follow routes and plan trips with accuracy.

What are the main differences between a fish probe and a plotter?

The plotter is a more advanced tool. However, it may not detect the depth and reveal the presence of fish if it is not integrated with a probe.

The fish tinders does not allow to view maps and nautical charts or track routes.

The ideal solution for anglers in both amateur and professional is the chartplotter sonar built-in. Cutters Garmin ECHOMAP™ or GPSMAP® allow you to add additional equipment such as probes advanced probes real-time scanning LiveScope®, radars, autopilots and switching systems digital. Some models of these ranges are combined in a single screen technology and probe mapping capabilities are more advanced.
