I have a transom mounted 360, hooked to an onix 10.the 20ft. ring is the offset I have chosen to use (on hummingbird core units, the offset is displayed as a line with blue dot at the end.the range rings would be displayed every 25.5 feet , for this particular range, that I have set, but I have turned, range rings off.
