Fishfinder Options

The fishfinder provides controls to select additional modes:
• Frequency – you can select the transducer frequency, 50 kHz for wide cov-
erage and deep water, 200 kHz for a detailed view, both frequencies simul-
taneously or auto-frequency. The default setting is auto-frequency, which
determines the optimum frequency of operation based on the current
depth.
• Bottom Lock – changes the operating mode to re-set the bottom. It pro-
vides a bottom-up view: the bottom is used as the reference, its image is
flattened and depths are displayed here. Bottom lock mode is used prima-
rily to filter-out the bottom structure and display fish details only.
