Lowrance Hook-7 Fishfinder Details
The Lowrance Hook-7 uses a simple set of physical controls: a LIGHT/POWER key, a directional keypad, and the PAGES, MENU, ENTER and ZOOM keys. To turn the unit on or off, press and hold LIGHT/POWER for three seconds. Pressing both Zoom keys at once saves a Man Overboard waypoint and automatically creates an active route back to it. When the unit is first powered on, a Setup wizard runs, and you can launch it again later by restoring defaults.
The Fishing modes are preset packages of conventional sonar settings. The options are General Use (1000 ft or less), Shallow Water (60 ft or less), Fresh Water, Slow Trolling, Fast Trolling, Clear Water, Brackish Water and Ice (all 400 ft or less), plus Deep Water (1000 ft or more). Lowrance recommends Fresh Water mode in water under 100 feet deep so the unit tracks the bottom properly. Reset fishing mode clears any changes you have made and restores that mode's defaults.
The conventional sonar menu has adjustments for Sensitivity and Colorline. Auto Sensitivity is on by default and still lets you change sensitivity by about +/-40%. The Trackback feature lets you scroll back through recent sonar history by moving the cursor left. Other tools include Noise Rejection, Surface Clarity, Split Zoom, Split Flasher, an Amplitude Scope and Fish ID, which shows echoes as fish symbols. The manual warns that Fish ID can show debris or structure as fish.
The DownScan page adds a Contrast control and color palettes suited to different conditions. White works well for suspended targets, Purple shows structure detail and bottom hardness, and Sepia is best for bottom detail. You can also overlay DownScan on the conventional sonar page. Stop sonar stops the transducer from transmitting, which prevents interference when two sonar units run on the same boat. Sonar logs can be recorded to a microSD card at a quality level you choose.
The Installation menu includes keel offset, water speed calibration for paddlewheel sensors, temperature calibration, reset water distance and transducer type selection. Turning on Advanced mode unlocks navigation settings such as arrival radius, off-course distance, magnetic variation and bearings. It also enables arrival, off-course and anchor alarms. In basic mode, the unit offers Shallow and Fish alarms. Standby mode turns off the sonar and display to save power, but leaving the unit in standby will still drain the battery.
When an AIS device is connected through NMEA 0183, the unit shows AIS targets. You can filter targets by distance and speed and open vessel details such as the MMSI number. Chart orientation can be set to North Up or COG. You can save a screenshot to microSD by pressing Power and then Zoom (+). Other features include a Simulator, a trip calculator, customizable overlay data, and QWERTY or Alpha keyboards for entering text.
