The performance of the technologies employed
in non-invasive surveys can be adversely affected by factors outside
of SUMO's control. Whilst SUMO uses all due diligence and
reasonable endeavours it does not warrant that 100% detection can
be achieved. Irrespective of the information provided by a
geophysical survey, any ground works should be undertaken with
extreme caution.
