Reading the Sonar display (PRO and CHIRP models)

Sonar readings (display) of Deeper PRO and CHIRP models provide crucial information about the water body, such as location of fishes, their approximate size, bottom hardness, weeds and their density, as well as underwater structure. It is also important to understand how various settings such as Beam angle and Color palette affect the sonar display and the amount of information it provides. You can find general information about how sonars display information and how to interpret it here: How...

Deeper PRO and CHIRP model series allow to choose between 3 different color palettes (Classic / Day / Night) Choosing the right color palette can help you with interpreting fish size and bottom features like hardness of weeds. Colors you see on the screen are important in understanding how strongly underwater objects reflect the sonar signal, which is a key factor in determining their size and thickness. ⓘ For best interpretation of fish size and bottom features, please use Narrow beam setting...

There are 2 ways you can detect fish and determine their size using the Deeper Sonar PRO and CHIRP models: by using Fish Icons or Detailed sonar screen mode (having Fish icons OFF). Using Fish Icons method Fish Icons option is the easiest way to locate fishes, and something that can be used if you don't have experience in reading the sonar screen. However, it is less accurate. When Fish Icons are enabled, special algorithms will analyze the sonar screen and mark ultrasound reflections from fi...

Understanding whether the bottom is soft or hard can be crucial when searching for a fishing spot. With Deeper PRO and CHIRP series, determining the bottom composition is extremely easy. Recommended settings: - Beam: Narrow (PRO and CHIRP models) or Mid (CHIRP models). Note: Do not use Wide beam for determining bottom hardness or features. Wide beam is not suited for accurate bottom feature detection. - Sensitivity: 90-100%, depending on how clear the water is. Reduce this setting...
