DiscovOre compatibility with other designs
The DiscovOre core barrel is compatible with most core barrel designs existing on the
market. Most components are interchangable. To convert other design core barrel into
DiscovOre in most cases there is only need to replace head assembly and overshot
head (surface application). In underground application (horizontal and up-hole drilling)
additionally there is requirement to change locking coupling (DiscovOre design) and
make sure that surface type adapter coupling is used (or the type with welded drive
key). See explanation of different types of locking and adapter couplings on next page.
DiscovOre core barrels are compatible ONLY with Arrow 3S overshots.
