The goal is to give you the best of both worlds so that you can know more about what's underneath your boat. TRUE Dual Frequency / Dual Beam Operation The Edge3 is not your run-of-the-mill dual frequency depth sounder. You truly have two separate sounders with two separate transducers with separate controls. [. . . ] Water Surface Temperature - Indicates the temperature of the water as reported by the temperature probe. Battery Voltage - Indicates the voltage of the power supply that is providing power to the Edge3. Clean Line Level - Indicates the level of the Clean Line feature for each beam. In split screen mode, this number is determined by the right beam. OPERATION Left Beam Beam Frequency Beam Gain Level Auto Strong Signal Strength Key Weak Current Mode (Determined by Right Screen) Right Beam Beam Frequency Beam Gain Level Auto Current Range Scale Left Beam Right Beam Water Surface Temperature Battery Voltage Clean Line Level (Left Beam) Clean Line Level (Right Beam) Red Lens (No Function) Water Depth Mode Power On & History Memory Instant High-Speed Mode Power Off Menu Alarm Speaker Gain & Range Right Beam Controls Auto Range Auto Gain Beam Select for Clean Line Control Clean Line Level Control & Menu Cursor Navigation Keys Favorite Feature Key & Menu Exit Gain & Range Left Beam Controls 8 Current Mode - Shows the currently active mode (1 - 4) Signal Strength Key - Shows the color verses signal strength for the selected color scheme. The stronger colors are represented towards the top of the key and the weaker color towards the bottom. The upper most color is the Clean Line color. A / R - Push to toggle on and off the Automatic Range Control feature. When Auto-Range is on, an "R" will show at the top of each beam display. The Auto-Range features maintains the best view of the bottom, according to the A-RNG-MODE menu setting for each beam. When this feature is off, you will need to manually change the range setting using the RANGE + and RANGE -- keys to keep the bottom in view over various water depth changes. When Auto-Gain is on, a "G" will show at the top of each beam display. The Auto-Gain feature tries to maintain the optimum gain level for the current depth, according to the A-GAINLEVEL menu setting for each beam. When this feature is off, you will need to manually change the gain setting using the GAIN + and GAIN -- keys to maintain the preferred gain level. When in Auto-Gain mode, you can temporarily increase the level, but the auto feature will readjust it again. When in Auto-Gain mode, you can temporarily decrease the level, but the auto feature will readjust it again. In split-screen mode, you have a set of range and gain keys for each beam. When in full-screen mode, either set of keys will control the full-screen beam. BEAM SELECT / C-LINE ADJ - The large round blue control is used to select the beam and then adjust its Clean Line level. The currently selected beam is indicated by a red colored gain level indicator. Press the or keys to change the selected beam, then press the or keys to adjust the Clean Line level. CONTROL PANEL KEYS ON / MEMO - Push and hold to turn the unit on. USER / CLR - Push to activate the configured "Favorite Feature". Press again to change the menu setting or use the and keys to change the current setting. The small menu will automatically exit three seconds after the last key is pressed. [. . . ] PULSE-LENGTH Pulse Length controls how long each "ping" of the transducer is. Longer pulse lengths allow better deep water performance but reduce resolution. Shorter pulse lengths give the best resolution, but have problems reaching into deep water. Its function is to reduce the surface clutter normally found in the first few feet of the water column by reducing the gain in this region. [. . . ]
