Controls the intensity of the sonar returns on-screen.
High Gain values provide returns for objects of all sizes and surface types.
Low Gain values will filter out smaller objects and softer surfaces.
NOTE: While the Gain value will vary based on user preference, the general goal is to strike a balance between providing solid targets, while not introducing an overwhelming amount of additional clutter.
Controls the maximum depth directly below the transducer that can be viewed on-screen.
Use Automatic to keep the lake or sea bottom in view
Use Manual to view a specific portion of the water column on-screen and exclude anything below the value chosen
Controls the maximum distance forward of the transducer that can be viewed on-screen.
Water clarity determines effective forward range. Clearer water allows for greater range.
Water depth determines the maximum effective forward range. The ratio on the AUTO setting is approximately 4:1 (4 foot forward for every 1 foot down)
NOTE: When first learning LiveScope, try to keep the Range values consistent while fishing. It will help learn how far to cast and determine the actual size of fish/objects in the water.
NOTE: The best way to learn what these settings do is to just spend time using them. Seeing real-time changes to the image on-screen, as incremental adjustments to settings are made, is going to be the most effective method of gaining understanding of what they do. If changes are made that lead to undesired results, returning to default settings is a quick way to start over fresh.
- Select from a set of 15 pre-determined color schemes.
NOTE: Some color schemes look different when a chartplotter is set to Night Mode. As a result, some color schemes work better depending on the time of day. Instructions on changing to Night Mode can be found in the Owner’s Manual for the chartplotter model.
Adjust this setting to tune the colors of returns higher or lower on the range of available colors. This range is dependent on the chosen color scheme.
Use a lower color gain setting to “flatten” returns to a more similar brightness
Use a higher color gain setting to make strong sonar returns brighter, making certain objects “pop” on screen
Determines which colors from the current color scheme will be visible for sonar returns.
Use a lower color limit setting to “limit” or “filter out” weak sonar returns
Use a higher color limit setting to “limit” or “filter out” stronger sonar returns
With the example above, notice how raising the Color Limit eventually hides weak returns and the edges of stronger returns (blue colors), leaving only stronger returns (yellow/green).
Noise Reject attempts to eliminate interference or technology-produced returns that are not actual objects in the water. Real objects can be impacted by adjustments to this setting but not to any significant degree.
Low – Filter out noise created by trolling motors as well as nearby transducers that are operating at a similar frequency
Medium – Capabilities of Low setting but also filters out artifacts created from hard surfaces (e.g. false bottoms)
High – Capabilities of Medium setting but with an additional filter to eliminate flickering noise (e.g. static)
Can create a slower refresh rate in the image
Unlike Noise Reject, which examines a broad array of target types, the Ghost Reject setting is solely focused on reducing the occurrence of duplicated or reflected returns. False Bottoms and Ghost Trees are examples of this behavior and can be produced when hard bottom surfaces are present.
NOTE: Ghost Trees can sometimes be a result of multiple types of targets and may require a combination of Noise and Ghost Rejects to sufficiently filter out.
Compared to Traditional Sonar, LiveScope tends to be used in shallower water. At these depths, TVG is primarily utilized to remove surface clutter and excessive noise from around the transducer.
Overall, the setting is used to lessen the impact that depth has on the brightness of returns. By raising the setting, returns near the surface will dim slightly and deeper returns will become brighter. The end result is that all returns should achieve a more uniform brightness level.
NOTE: The low setting is generally the best starting point. Raising too high may aggressively filter and hide desired targets in shallower water.
Provides an ON/OFF toggle for utilizing the internal sensors to stabilize sonar returns. When disabled, the image will not be able to automatically account for boat movement, but a Pitch Angle adjustment can be manually entered to account for any consistent deviations to the expected angle.
Initiates a calibration wizard that provides step by step guidance for calibrating the internal compass of the LiveScope transducer. This is a useful tool for ensuring the direction of the Beam Icon is accurate.
NOTE: A poor calibration could cause stabilization errors.
Allows manual control of the sonar viewing mode (Forward / Down / Perspective) or have it done automatically (Auto). If manually choosing the mode, the transducer must then be physically oriented to match the setting.
NOTE: A compass calibration is stored to memory based on the orientation of the transducer when the calibration occurred. Physically switching the orientation (i.e. Down to Forward) will require a new calibration to the compass. For more info, see section ‘Calibration Considerations’ in Related Content.
This allows a user to correct misalignment that may be visible where the LiveScope beam sectors meet. This can cause targets passing through this boundary to appear pulled apart.
NOTE: It is highly recommended to always use the appropriate AUTO setting for the body of water (fresh vs salt) the vessel is in.
