What is the diameter of the bottom covered by different beams of the Deeper CHIRP series, PRO+2?

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 covered by each beam of the Deeper CHIRP.
 

Depth (m) Narrow beam    Mid beam    Wide beam Depth (ft) Narrow beam    Mid beam   Wide beam 
  675 kHz, 7°   290 kHz, 16°   100 kHz, 47°   675 kHz, 7°   290 kHz, 16°   100 kHz, 47°
