I understand that if a sorry thief wants something they will go through great lengths to get it but I don't want to make it a cakewalk either. There are various types of padlock shackles and other lock protection devices but what I'm looking for is something heavy duty. Over the years, I've seen some nice inventions barring entry to oil and gas leases as well as big ranches. One of which was a lock concealed inside of a steel collar or pipe. Another was a large cylinder type device with many different locks on top of it, I think you move the cylinder around to your lock? If anyone has some plans on how these go together please IM me. I'm open to all other tamper proof devices as well. I'm already positioning game cameras that will at least capture them in the act and their vehicle. I hate thieves.
