The Global Positioning System (GPS), originally NAVSTAR GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

A leap into the future of sonar, Dragonfly sonar displays employ true wide-spectrum CHIRP technology. With wide-spectrum CHIRP more sonar signals are transmitted into the water, allowing Dragonfly to interpret more detail, target more fish, and image structure with unmatched clarity.

A BETTER VIEW

Each Dragonfly is engineered with optical bonding LCD display technology. Once only available on high end marine displays, Dragonfly’s all weather optically bonded displays deliver brighter colours, sharper contrast, and are guaranteed never to fog up.

MOUNT ANYWHERE
