* Ping Rate Hyper Ping is a setting only available on
Traditional internal and Legacy sonar modules, for
use in shallow waters (depth range set to 6 meters
(20 feet) or less. In depths of over 6 meters (20
feet) the ping rate will revert to normal until depth
conditions are met.

the ping rate limit to suit local conditions. For
