WEEE compliance may not be required in your location for electrical & electronic equipment (EEE), nor may it be required for EEE designed and intended as fixed or temporary installation in transportation vehicles such as automobiles, aircraft, and boats. In some European Union member states, these vehicles are considered outside of the scope of the Directive, and EEE for those applications can be considered excluded from the WEEE Directive requirement.

How Sonar Works Sonar technology is based on sound waves. The 300 Series™ Fishfinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 300 Series™ Fishfinder sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object. S

When all the echoes are viewed side by side, an easy to interpret “graph“ of the bottom, fish, and structure appears. The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited. High frequencies (200 kHz) are commonly used on consumer sonar and provide a good balance between depth performance and resolution. Low frequencies (83 kHz) are typically used to achieve greater

DualBeam PLUS™ Sonar (DualBeam PLUS™ models only [385ci]) Your 385ci Fishfinder uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of coverage. DualBeam PLUS™ sonar has a narrowly focused 20° center beam, surrounded by a second beam of 60°, expanding your coverage to an area equal to your depth. In 20 feet of water, the wider beam covers an area 20 feet wide. DualBeam PLUS™ sonar returns can be blended together, viewed separately, or compared side- by-side. DualBeam PLUS™ is id

Down Imaging™ Sonar (Down Imaging™ models only [385ci DI]) Your 385ci DI Fishfinder uses Down Imaging™ technology. The Down Imaging™ transducer scans the water with razor-thin, 45° 800kHz high-definition beams. The beams are wide 75° 455kHz (side to side) but very thin front to back. 16° 455kHz The Down Imaging™ beams can be operated 25° 200kHz at two frequencies: 455 kHz (75°) or 800 kHz (45°). Select 455 kHz for the best overall 75 Degree Total Coverage image quality and depth. Select 800 kHz

Dual Beam Ice Transducer Ice transducer (optional-purchase XI 9 20 Ice Transducer only) Your Fishfinder supports the optional- purchase XI 9 20 Ice Transducer which provides selectable dual-frequency sonar with a wide area of coverage. Selectable dual-frequency gives you the option of two beams, and both beams will cover the bottom and provide high definition. The 20 degree center beam provides the highest definition, while the 60 degree beam provides wider coverage. Depth capability is affected

How GPS Works Your 300 Series™ Fishfinder also supports GPS (Global Positioning System) and chartplotting. It uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information. GPS uses a constellation of satellites that continually send radio signals to the earth. The GPS receiver on your boat receives signals from satellites that are visible to it. Based on time differences between each received signal, the GPS receiver determines its distance to
