Fishfinder Features

Overview: The Garmin Striker 7sv is a compact fishfinder/GPS navigator, designed for use in small watercraft. It features a 7" WVGA color display and a 500-watt dual-beam sonar transducer with CHIRP to help you locate fish in up to 1900 feet. The Striker 7sv also has an integrated GPS to help you locate and navigate to your favorite fishing holes, docks, and boat ramps.

CHIRP Sonar: The Striker 7sv is equipped with the 500-watt Garmin GT52HW-TM transducer which has both CHIRP (77/200 kHz) and CHIRP DownVü/SideVü (455/800 kHz) sonar, two of the most sophisticated sonar technologies available for boaters and fishermen. Compared to standard sonar, which sends one frequency at a time, CHIRP (Compressed High-Intensity Radiated Pulse) sends a continuous sweep of frequencies within a range from low to high. As a result, CHIRP sonar creates much greater target separation and crisper fish arches.

Display: The Striker 7sv features a 7" (diagonal) WVGA color display with 800 x 480 pixels. The display has a horizontal orientation with 10-level backlighting (0% to 100%). The unit comes with a mounting frame that sits on a 360° swiveling base. You can easily adjust the tilt of the display as desired.

Keypad: The Striker 7sv features a convenient keypad for operating the device. The keypad consists of seven buttons and a 4-way control:

• 4-way Control: The 4-way control lets you scroll, highlight options, and move the cursor. It also lets you zoom in and out of a view.
• Return: The Return button returns you to the previous screen, or to the home screen when held.
• Menu: The Menu button opens and closes the menu page.
• Power: The Power button turns the unit on and off. It also lets you quickly adjust the backlight or color, and disable the sonar, when you quickly press and release.
• Check: The Check Mark button selects the highlighted option and acknowledges messages.
• Waypoint: The Waypoint marks the present location as a waypoint, allowing you to navigate to that point at a later time.
• Zoom: The "+" and "-" buttons let you zoom in and out of a view.

Transducer: The dual-frequency GT52HW-TM transducer with Garmin CHIRP DownVü and SideVü scanning sonar. The transducer provides ultra-clear sonar pictures of objects, structure, and fish that pass below your boat. It includes CHIRP traditional sonar at 50, 77, and 200 kHz frequencies for returns from depths of up to 2300 feet in fresh water (1100 feet in saltwater), plus CHIRP DownVü/SideVü sonar at 260, 455, and 800 kHz for greater accuracy in shallower depths down to 500 feet (DownVü) as well as 500 feet left and right (SideVü). The transducer also has a fast response water temperature sensor. The Striker 7sv includes mounts for installing the transducer on the transom of the boat, or to the bottom of your trolling motor.

Viewing Pages: The Striker 7sv's display scrolls from right to left to show the sonar readings from the transducer. The bottom depth is displayed in large numerals, along with the water speed, device voltage, and the current time. The unit has an adjustable depth range (Auto or Manual), and the depth scale is shown at the bottom of the screen, along with the transducer frequency. You can choose from a full screen page or split pages:

• Full Screen Page: The Full Screen page shows a full-view graph of the sonar readings from the transducer.
• Split Zoom Page: The Split Zoom page shows a full-view graph of the sonar readings on the right side of the screen, and a magnified portion of that graph on the left side.
• Split Frequency Page: The Split Frequency page shows the 77 kHz frequency sonar data on one side, while the other side shows the 200 kHz frequency sonar data.

Flasher: The Striker 7sv also includes a Flasher Page, which shows sonar information on a circular depth scale to indicate what is directly beneath your boat. The Flasher display page shows the depth and device voltage.

A-Scope: The A-Scope is a vertical flasher along the right side of the Full Screen page that shows the range to targets in real time along a scale. This view expands the most recently received sonar data so that it is easier to see. It can also be helpful in detecting fish that are located close to the bottom.

Beeper/Alarms: The Striker 7sv has a beeper that will sound to confirm each button press, or can be set to sound only for alarms, or turned off completely. There are several audible alarms that can be independently set in the menu:

• Navigation:
  • Arrival: The unit's alarm will sound when you are within a specified distance or time from a turn or destination.
  • Anchor Drag: Sets an alarm to sound when you exceed a specified drift distance while anchored.
  • Off Course: When you are off course by a specified distance, the alarm will sound.
• System:
  • Alarm Clock: You can set an alarm clock to sound at a specific time.
  • Device Voltage: The alarm will sound when the battery voltage reaches a specified low voltage.
  • GPS Accuracy: The alarm will sound when the GPS location accuracy falls outside a user-defined value.
• Sonar:
  • Shallow: The unit will alarm when the water depth is shallower that the set value.
  • Deep: The unit will alarm when the water depth is deeper than the set value.
  • Fish: The unit will alarm when the device detects a suspended target. You can set the alarm for all fish, medium and large fish, or large fish only.
  • Water Temperature: The unit will alarm when the water temperature varies more than +/- 2°F. (Temperature-capable transducer required)

Navigation Features

Built-in GPS: The Garmin Striker 7sv has a built-in GPS receiver in the display unit that collects satellite data to establish your current location. The display unit should be mounted in a location that has a clear view of the sky for the best and most accurate results. A 5-bar signal strength meter indicates the quality of the satellite signal being received.

Waypoints: Waypoints are locations that you record and store in the device's memory. Waypoints can be marked at your present locations, or you can enter the coordinates to a waypoint at a different location. Each waypoint can be saved with a name, symbol, depth, water temperature, and comments. Once a waypoint has been saved, you can select and navigate to its location. You can also measure the distance to the waypoint on the Waypoint Map.

Man Overboard: From any screen, you can press the Waypoint button to mark your present location, and designate it as a Man Overboard (MOB) location. The Striker 7sv will then provide a direct route back to the location. MOBs and other waypoints can be deleted one at a time, or all at once, in the menu.

Routes: A route is a sequence of waypoints or locations that leads you to your final destination. To create a route, you can pick a starting point, add additional waypoints or locations, add turns, and save. Saved routes can be edited by changing the name, waypoints, or turns. Routes can be deleted one at a time, or all at once, in the menu.

Tracks: A track is a recording of the current path of your boat. You can designate a color for each track to differentiate them from each other. Tracks are created by automatically marking the current location at a set interval. The interval can be adjusted--recording more frequent plots increases accuracy, but fills up the track log quicker. You can also record tracks by the distance between points, or the variance from your course.
