Sonar Beam Configurations

Humminbird products have several different sonar beam configurations:

	A Single Beam covers a 16-24 degree range depending on the fishfinder unit, and reaches a depth of 600-1000 feet. The ID+™ fish identification marks the size and depth of detected fish in the beam's range.
	For broader coverage, the Dual Beam offers 600-2000 foot of depth depending on the fishfinder unit. In addition to the precise center beam, a second beam of 53 degrees surrounds the first beam expanding the coverage around your boat to an area equal to your depth - in 20 feet of water, the wide beam covers an area 20 feet wide. The dual beam ID+ fish identification is always visible on-screen: fish in the center beam are solid, fish in the wide beam are hollow.
	For the widest coverage, the Tri-Beam uses three sonar beams to form a continuous 90 degree area of uninterrupted coverage and reaches a depth of 600-1000 feet depending on the fishfinder unit. A precise center beam locates fish and detailed bottom structure, while two wide beams look to the left and right to cover an area TWICE your depth - in 20 feet of water, the wide beams cover an area 40 foot wide. The tri-beam ID+ fish identification display fish in the center beam as solid, fish in the wide beams as hollow and point left or right indicating location.
	The Wide Side uses three sonar beams to keep an eye on bank and bottom structure. A center sonar beam shoots down to 120 feet while port and starboard signals spread out 120 feet in either direction.
	Six separate beams provide excellent contour and shape for on-screen 3D display clearly depicting bottom structure and drop-offs. The six beams provide 53 degrees of continuous coverage up to 240 feet deep.
