Gordon Campbell from Aspect Surveys, UK, is asking to include the Layback value into the Spreadsheet so it can be verified and exported. Currently there is no such an item in both editors spreadsheets. I only suggested him to open a RAW file in Notepad and check the CAB strings... I guess it is more important for the mag data since most of mags are on the towfish?
CAB records hold all of the information if they towed the mag so maybe we can take the information from there.
