Charge the device completely. The status LED and the device turn off when the device is fully charged.

Automatic On and Off
The device turns on automatically when you put it in the water or when you connect it to USB power. The device stays on as long as it is in the water, which can be helpful for finding lost devices (GPS models only) (Locating the STRIKER Cast Device Using the Chart, page 3). The device also stays on as long as the app is connected. The device turns off automatically after 2 minutes of being disconnected from the STRIKER Cast app and out of the water.

Connecting a Mobile Device

You must connect the STRIKER Cast device to the STRIKER Cast app on your mobile device to see sonar data. TIP: The status LED flashes red or green and red when the device is ready to connect to the STRIKER Cast app.

From the app store on your mobile device, install and open the STRIKER Cast app.
Sign in to your Garmin® account.
TIP : If you do not have an account, select Create One.
Put the device in water, with the two pins in contact with the water, to turn on the STRIKER Cast device and prepare it to connect.

TIP: You can also connect the device to USB power and then immediately disconnect it to turn on the device and prepare it to connect. The status LED flashes green and red when the device is ready to connect to the STRIKER Cast app.
TIP: As a third option to pair, you can connect the device to USB power. The status LED flashes red when the device is ready to connect to the app when connected to power.

Select Connect your STRIKER Cast > Start.
Select your device from the list. The serial number is printed on the bottom of the device.

After you connect successfully, a message appears, and you can see sonar data when the device is in the water.

Attaching a Fishing Line or Tether

You can use the included nylon tether or attach the device to a fishing line on a fishing rod.

Attach the included nylon tether to the device.
Attach a 20-lb. test or higher fishing line to the device using a #3 barrel swivel with a snap, on a medium-action or heavier fishing rod.

Fishing with the STRIKER Cast Device

To avoid injury, always be cautious of your surroundings when casting the device.

Towing the device behind a vessel moving at speeds faster than 8km/h (5 mph) or in choppy water conditions could result in poor sonar performance and injury.

Garmin is not responsible for lost devices.

To prevent corrosion, do not store the device in water, and thoroughly dry the device after use.

You can fish with the device in various ways.

Cast and leave the device on a dedicated fishing rod so that you can continually change the device location.
NOTE : Repeatedly casting the device as you fish provides a clearer picture of what is below the surface. This is the recommended mode of use.
Cast and tie off the device using the included tether.
Tether the device behind a small vessel, such as a kayak.

TIP: It is recommended to tow the device behind canoes and kayaks, but not recommended to tow the device behind power boats while underway. Cast and leave the device on a dedicated fishing rod so that you can continually change the device location.

TIP : If the sonar view does not show returns, a small air bubble might be trapped on the pins near the power connector. Re-cast the device or tug on the line to clear the bubble.

TIP : If the sonar view shows repetitive bands, the STRIKER Cast device is likely in very shallow water. The bands are echos in the sonar returns. You can adjust the range to resolve this problem.

Adjusting the Level of Detail
You can control the level of detail and noise shown on the sonar screen by adjusting the gain. If you want to see the highest intensity signal returns on the screen, you can lower the gain or brightness to remove lower intensity returns and noise. If you want to see all return information, you can increase the gain or brightness to see more information on the screen. This also increases noise , and can make it more difficult to recognize actual returns.

Select Sonar > .
Under Gain , select an option:

To allow the device to adjust the gain automatically, select Auto.
To increase or decrease the gain manually, use the slider.

Adjusting the Range of the Depth Scale

Allowing the device to adjust the range automatically keeps the bottom within the lower or outer third of the sonar screen, and can be useful for tracking a bottom that has minimal or moderate terrain changes.
Manually adjusting the range enables you to view a specified range, which can be useful for tracking a bottom that has large terrain changes, such as a drop-offs or cliffs. The bottom can appear on the screen as long as it appears within the range you have set

Select Sonar .
Under Range, select an option:

To allow the device to adjust the range automatically, select Auto.
To increase or decrease the range manually, use the slider.

Sonar Settings
Select Sonar > > More Settings.

View: Shows a Traditional sonar view or a Flasher view (Flasher View, page 2)

Frequency : Adjusts the frequency to adapt the sonar for your particular goals and the present depth of the water. The 455 kHz setting uses a narrower beam width and is better for rough sea conditions. Bottom definition and thermocline definition can be better when using a higher frequency.
The 260 kHz setting uses a wider beam width, which covers a larger area and can allow you to see more targets, but also could generate more surface noise. Wider beam widths generate larger arches for fish target returns, making them ideal for locating fish. Wider beam widths also perform better in deep water, because the lower frequency has better deep water penetration. They can be used to search for structures such as brush piles.

Scroll Speed: Sets the rate at which the sonar scrolls from right to left. A higher scroll speed shows more detail, especially while moving or trolling. A lower scroll speed displays sonar information on the screen longer.

A-Scope: Displays a vertical flasher along the right side of the screen that shows instantaneously the range to targets along a scale.

Fish Symbols : Sets how the sonar displays suspended targets.

Restore Sonar Defaults : Restores the factory default settings for the sonar view.

Turning On the Flasher
Select Sonar > > More Settings > View > Flasher > Back.

Flasher View
The flasher shows sonar information on a circular depth scale, indicating what is beneath the STRIKER Cast transducer. The flasher is organized as a ring that starts at the top and progresses clockwise. Depth is indicated by the scale inside the ring. Sonar information flashes on the ring when it is received at the depth indicated.

The flasher colors indicate different strengths of the sonar return. The default color scheme follows a traditional sonar color palette, in which yellow indicates the strongest return, orange indicates a strong return, red indicates a weaker return, blue indicates the weakest return, and white indicates no return.
