Few things are more annoying than not being able to obtain documentation for old logging tools and panels.  At least two manufacturers currently refuse to supply schematics to subsequent owners.  This is an unacceptable practice and should not be tolerated by the industry.  Others are simply impossible to deal with.  Even before Halliburton closed the doors at MLS, getting an old schematic or manual from them was next to impossible.

Several manufacturers have a bad attitude about supplying documentation to independent repair facilities.  Again, this is an unfair practice and the industry should not tolerate it.  Computalog's current policy is unknown, but they have refused to sell us schematics in the recent past (despite doing so for many years prior to said refusal). 

We would never suggest that manufacturers have a duty to furnish free schematics to one and all.  But, they should be willing to sell schematics at a reasonable price, a price that would allow them to make a profit from the endeavor.

AnaLog Services, Inc. has a large library of schematics and other technical documents.  We always try to help anybody in need of documents we have.  We are also always looking for schematics, manuals, etc. not in our library; if you have something we need, perhaps we can do some horse trading.
