Survey Flags

Plain Survey Marker Flags

Bud Blackburn invented a machine over 65 years ago that glued vinyl flags to a wire staff. That first order of flags was sent to land surveyors.  These versatile plain survey marker flags have many uses beyond surveying. Sometimes called construction flags or locate flags.  Survey marker flags or pin flags are recognized universally.  They are a low-cost, high-visibility solution to attracting attention where you need it.
