Ping depth limit
When high-powered transducers are searching for a bottom lock, they can search down to a maximum of 3,048 m (10,000 ft), during the sonar’s hunt cycle. This means it can take some time to acquire or re-acquire a bottom lock. To help improve sonar bottom lock re-acquisition time on high powered transducers, a ping depth limit can be set.
The Ping depth limit setting is NOT available on CP-Series sonar modules (e.g.: CP370, CP470 and CP570).
When using a CHIRP or non-CHIRP high power (greater than 600 W) transducer connected to the 1 kW transducer, the Ping depth limit control will be available in the Fishfinder app’s Transducer settings menu: .
The Ping depth limit should only be enabled when problems are experienced re-acquiring depth readings after the sonar has lost depth readings.
Once Ping depth limit is enabled, when sailing in waters deeper than the specified depth limit, the Fishfinder app / transducer will not be able to establish a depth reading / bottom lock.
The Ping depth limit control enables you to specify a depth limit that your sonar will search down to. It is recommended this limit is set to a depth of approximately 25% to 50% deeper than the maximum water depth you want to use your Fishfinder in. E.g.: In 200 ft max depth water, the ping depth limit should be set between 250 ft and 300 ft.
