The FL-18 boasts features and performance previously not available on a three-color flasher depth finder / fish finder. The FL-18 offers a patented split screen flasher display. This allows you to zoom-in on the bottom six feet while watching the entire water column at the same time in real time! The Bottom Lock feature stays locked on the bottom even as the boat is bouncing up and down in big waves! With a target ID of less than 1/2 inch, the FL-18 makes fish easy to spot! The FL-18 depth finder / fish finder is equipped with features like a built-in shallow water mode for fishing waters under 15 feet. Five depth scales down to 200 feet. Built-in interference rejection. A 3-color LED readout that tells you if the targets you see are weak (green) medium (orange) or strong (red). The Ultra Pack systema€ s innovation begins with a 12 volt, 9 amp-hour battery enclosed inside the case, so you dona€ t need to connect or disconnect your battery after each use. A master power switch powers up your unit and remote charging posts make it easy to re-charge. The Ultra Pack now comes with the all new FL Digital Depth Indicator, giving you an easy-to read digital depth readout, plus the ability to check your battery level with the push of a button. The case comes with an adjustable rod holder, cable storage cleats, battery charger and even your own Vexilar tackle box! The super tough Ultra Pack will fit into a five gallon bucket. An optional soft carrying case is also available. The Ultra Pack comes completely assembled, individually tested and ready to fish. It also includes an instructional video. Features: Auto Zoom Mode (AZ) - Gives a half screen zoom window of the bottom 6 feet of depth. No matter if you're in 10 feet or 100 feet, the bottom 6 feet always fills half of the screen. Bottom Lock Mode (BL) - Works the same as Auto Zoom, but locks the bottom so it will not move with changes in depth or boat motion. Spot a Walleye near the bottom at 40 m.p.h! Low Power Mode (LP) - Reduces the output power by 50%. This feature takes the place of the Vexilar S-Cable. Both the AZ and BL modes are available within the LP mode.
