How to set sonar frequency and sensitivity?

1. Click the "Settings" icon in the upper left corner of the sonar display, and the sonar settings interface will automatically pop up.

2. Click the settings icon and a menu for setting frequency and  sensitivity will appear at the bottom of the screen.

Freq：

7 degrees - 680k High-frequency beam with a range of 0.3-30 meters (30 meters verified) and 1 cm resolution allows for ultra-sharp and highly detailed fish arches and crisp bottom contours, making it easy to identify individual fish even in shallow waters.

20 degrees - 200k Mid-Frequency Beam (range of 0.5-100 meters, 30 meters verified), resolution of 2.4 cm ). The perfect combination: clear structural imaging with extended depth penetration. Ideal for scanning steep slopes, tracking baitfish schools, or fishing at transition depths.

47 degrees - 100k The Low-Frequency Beam has a range of 0.8 to 30 meters (30 meters verified) and a resolution of 2.4 cm. The Wide Mode provides maximum coverage for finding baitfish clouds and large game fish. Its advantage in deep water is that it maintains clarity when targeting fish at greater depths.

Understanding Sensitivity:

· Lower Sensitivity Values: Preserve more detail (less filtering).

· Higher Sensitivity Values: Apply more filtering, resulting in a cleaner display.

Setting Your Sensitivity:

You can adjust the sensitivity level based on your personal preference and experience.

Our Recommended Approach:

· Start Low: Begin with a relatively low sensitivity setting.

· Increase Gradually: Slowly raise the value.

· Find the Sweet Spot: Stop when the display is readable (low clutter) but still shows good detail in the sonar returns.

As your experience grows, mastering this feature will significantly enhance your ability to locate fish and identify underwater structures.

Background：

NDS APP supports three modes: Dark is suitable for use at night, Light is ideal for use in bright light, and NDS Mode creates a unique display style that is distinctive to our brand.
