What is the diameter of the bottom covered by different beams of the Deeper? (PRO / PRO+ / Deeper Start models)

Home > Knowledgebase (F.A.Q.) > EN > Deeper Sonar features and specs > What is the diameter of the bottom covered by different beams of the Deeper? (PRO / PRO+ / Deeper Start models)

Deeper Sonar devices scan in a form of a cone. Area of the bottom that the sonar beam covers increases based on the depth of the area you're fishing at, as well as the beam angle you're using.

Please see the below comparison chart, which shows the diameter of the bottom that each beam covers (Deeper PRO, PRO+ and Start models).

Depth (m.) 290 kHz 15º (Narrow beam)   90 kHz 55º (Wide beam)   120 kHz 40º (Deeper Start)   Depth (ft.) 290 kHz 15º (Narrow beam)   90 kHz 55º (Wide beam)   120 kHz 40º (Deeper Start)
