[DG11] Sonarchart Live, depth offset

[Derek - Raymarine - Moderator]

Hi moki38

The Navionics article indicates that

"Keel Offset applied - SonarChart Live will ignore the Keel Offset so that the contours drawn more closely reflect the true water depth which is the depth below the transducer plus any tide adjustment". They further indicate that "We do not know the waterline depth setting in this case . . . . is the most true depth we can calculate without knowing waterline offset. This is simply the depth below transducer adjusted for tide."

Basically, this provides for an depth which may not be accurate and so in this case Raymarine have decided not to allow Keel offsets and only allow waterline offsets in order to represent a more accurate depth.
