Lowrance’s Hook-3X Sonar: For an Incredible Fishing Experience

Fishing is not everyone’s cup of tea and therefore the device to be used by a fisherman or an angler also has to be unique. For someone who loves water and fishing, the experience is novel every time they enter the open water.

In the olden days when there were no devices or technological miracles, fishermen and anglers had to trust their intuition or develop techniques when they fished.
However, the world has moved on and every day, technology gets better. And this is why anglers now have something to trust to find the right spot for fishing or for detecting danger: Sonar technology makes this possible

The Hook-3X Sonar, a creation of Lowrance Marine Electronics, is a fish finding device that uses sonar technology to detect fish and schools which are otherwise not visible.
Lowrance Marine Electronics has time and again proven itself as one of the leading companies in marine technology and industry. It has also garnered multiple awards within the marine industry.
