Ground reconnaissance by Network Archaeology and geophysical survey carried out by the Bartlett-Clark Consultancy in 1998 at The Coppice (between SU83719738 and SU83509769) failed to locate any evidence of the earthwork extending to the southeast beyond SU83509769 (B17, B19).

Negative evaluation to east of Grim's Ditch carried out in August 2004 by Wessex Archaeology (B25).
Negative evaluation to west of Grim's Ditch in RAF High Wycombe carried out in early 2006 by Oxford Archaeology (B26).
Evaluation trial trenching carried out in July 2008 established the position of Grim's Ditch [on the eastern edge of the scheduled area, 17.5m NE of the assumed ditch line] surviving to a depth of 0.8m and with an estimated width of 6.8m. The uppermost 0.3m of fill appears to be a modern landscaping layer, possibly deriving from the construction of nearby tennis courts. No evidence of associated features or dating evidence was found.
