• Easiest-to-use interface
• CHIRP sonar for best target separation and minimal clutter
• ASP advanced signal processing for hands-free adjustment of sonar settings
• Downscan imaging for photo-like images of the bottom and structures
• Downscan overlay to see CHIRP scans overlaid on downscan imagery
• Trackback to let you review sonar history and set waypoints
• Highly accurate built-in GPS antenna with detailed US map
• Quick-release bracket and multiple mounting options
The Hook 7 fishfinder is a 9.26in x 3.0in x 5.95in unit that includes a brilliant 7-inch 800×480 pixels high-resolution back-lit color LED widescreen display, easily visible in open air marine environments amid glare from sky and sunlit waters. The Lowrance Hook 7 is compatible with a variety of Lowrance and Airmar transducers, and is available bundled with a low/mid/downscan transducer to match the EchoSounder operating frequencies of 455/800 kHz (DownScan Imaging™), and Mid, High 83kHz/200kHz (CHIRP).
The easy-to-use user interface controls consisting of a Keypad, Menu button, Power/Light, Pages, Zoom In/Out, and Enter buttons. The Power/Light button turns the unit On/Off and lets you select from ten levels of LED back-lighting. The Menu button opens settings, context, and page menus while the Pages button allows you to select among both full-screen and split screen display options to present the most useful information about the water underneath your boat. The Hook 7 will display vivid Sonar, Downscan, Steer, and Chart pages, as well as preset split-screen combination pages showing Chart/Sonar, Chart/Downscan, Sonar/Downscan, and Chart/Sonar/Downscan. Split screen results on the widescreen display present you with multiple sources of information, and allow other custom data combinations of your own choice.
With the Hook 7, hands-free automatic tuning of sonar settings is offered via ASP advanced signal processing. The ASP is used by the Hook’s Noise Rejection feature to monitor the effects that noise from boat pumps, water conditions, engine ignition systems have on your display and filters them out.
The Hook’s conventional sonar can be tuned for various types of fishing environments that match water depth and inland or coastal topography: general use, fresh water, deep water, slow trolling, fast trolling, clear water, brackish water, and ice. The Surface Clarity setting decreases the sensitivity of the receiver near the surface to reduce clutter from excessive surface detail. However, conventional single-frequency sonar has the disadvantage that reducing sensitivity also causes you to miss fish targets whereas increasing sensitivity also increases clutter on the display both near the surface and in the water column. Lowrance CHIRP (Compressed High Intensity Radar Pulse) sonar will transmit instead a modulated pulse of multiple frequencies resulting in better image quality, the better fish target separation near cover, and greater depth penetration with minimal clutter.
The downscan sonar imaging offers photo-like images of the water column, structures, and bottom, to help locate fish and fish-holding structures. The downscan overlay places downscan imagery over CHIRP sonar returns, making an easy target out of those fish holding tight to their cover.
The Lowrance Hook series offers the widest choice of compatible mapping packed into one head and one transducer. The Trackback feature allows for reviewing sonar history, taking a closer look at promising areas, and placing waypoints on key fishing areas. What’s more, you can use your own sonar logs transformed into Insight Genesis custom maps. The highly accurate 5Hz built-in GSP antenna works with WAAS + EGNOS + MSAS, and the standard charts include a detailed US map featuring over 3,000 rivers, lakes, and coastal contours down to 1,000 ft, and a worldwide reference base map. Optional chart upgrades include Nautic Insight PRO, Lake Insight, Jeppesen C-MAP, Navionics +, and more.
The multiple mounting options offer multiple choices of the most convenient ways to attach the unit. The quick release bracket let you take the Lowrance Hook 7 around with you. Lowrance fishfinders support 31 languages in regional packs.
The Lowrance Hook 7 fishfinder offers any serious angler a combination unit with the essential features for a rewarding fishing experience at a good price.
