A number of photographs and a grid reference were obtained and passed to Humber CGOC and Explosive Ordnance Disposal experts.
A cordon was put in place around the object until EOD officers arrived.
It turns out that the device was one which would have been used to slow the descent of explosives from aircraft, but it didn't actually contain explosives itself.
It didn't have any explosives attached, so was removed from the beach and disposed of.
A spokesman for the Coastguard said: "On this occasion the object was found to be part of a retardation device used to slow the descent of explosives from low flying aircraft.
"The device was found not to have any explosive attached and was removed from the beach for safe disposal.
"We would always ask that if you find any unusual objects on the beach that they left alone and dial 999 and ask for the coastguard.
"We would like to thank all the members of public for their understanding during this incident while a section of the beach was closed."
