[CA] [CA11] frequency tuning on b60 50/200 kz transducer

[Chuck - Raymarine - Moderator]

Wade,

Frequency adjustments are most commonly made to increase sonar sensitivity to specific biological species within the water column (i.e. some species are more reflective of sonar energy at some frequencies than others). Accordingly, this feature would be adjusted base upon experience for the type of organisms being sought. To a lesser degree, this feature is used to increase/decrease the diameter of the transducer's cone angle. In the case of the latter, the increases would be greater when adjusting the 200kHz frequency than when increasing the 50kHz frequency.
