8= ENABLE DIGITAL AVERAGING 9= DISABLE DIGITALAVERAGING
The digital sonar in the X-50 is a highly sensitive sonar that gives extremely rapid updates of the water depth. Under most conditions, the bottom contour changes so rapidly that the depth display can appear to "jitter". In otherwords, the displaywill change the depth so quickly that it can be difficult to determine the actual bottom depth. To alleviate this situation, the X-50can averagethe bottom readings and place the result on the display. When the X-50 is firstturned on, averaging is enabled. To disable averaging, press the 9 key once the menu appears. To enable averagingonce again, press the 8 key.
