Chart Speed: Chart Speed is a user-controllable feature that sets the speed at which sonar information moves acros s t he displa y. A fa ster setting display s sonar information from more pings and shows more detail, but the information moves qui ckly ac ross the dis play: a s lower set ting p ermits vie wing of m ore sonar history, but does not display as much detail. The best setting is often the user’s personal choice.

Cone Angle: The cone angle is the angular measurement of the sonar beam at a specific dB down point (i.e. -10 dB). See dB Down Point.

Customizable Di gital Reado	uts: Customiza ble Dig	ital Readouts is a
Humminbird® feature that permits t he u ser to s elect		the specific digital
information that appears in the	main So nar v iew (i.e. Sp eed, Temperature,
Barometric Pressure, TripLog, etc.)

Dead Zone: The dead zone is the area of the sonar beam that receives the sonar signal after the main bottom return. Fish and other objects close to the bottom that fall within the dead zone will probab ly not be visible in the sona r beam. Precision sonar beams , s uch as t he Hum minbird® 20° b eam, have a sm aller dead zone than wider sonar beams.

Decibel: A D ecibel is the m easurement for s ound pressure l evel, or “intensity”of the sonar return. See dB Down Point.

dB Down Point: The dB Down Point is the standard decibel level at which the sonar cone angle is meas ured, and is wr itten as “@ -1 0 d B” or “@ -3 dB“. Measurements at smaller down points (bigger negative numbers) indicate that the less intensive sonar signals are being used for the measurement.

Display, FSTN: FSTN is an acr onym for Film Super-Twist Nematic. FSTN is a monochrome display technology characterized by black, high-contrast pixels. All monochrome fixed mount Humminbird® products use FSTN technology.

DualBeam PLUS™: DualBeam PLUS™ is a Humminbird® sonar configuration that uses two sonar beams simultaneously, and combines the information from both beams into one view by overlapping the d ata on-screen, or shows each beam individually side by side, or permits each beam to be viewed individually full screen.
