The advanced software of this instrument constantly filters out depth readings from your transducer which are due to water turbulence or marine debris, giving optimum accuracy in the range 0.4 to 1BO M (1.3 to 600 Ft) above hard bottom, displaying the result in figures and on an adjustable digital annulus.
Other functions available are a Deep (DEEP) and Shallow (SHALLW) alarm, and an Anchor Watch (ANCHR) which will sound an alarm when drifiting into shallower or deeper water when at rest.
N.B. To ensure data is accurate your transducer must be installed correctly. Please refer to the instructions supplied with your transducer.
