Hello everyone. I am a former Smokejumper (thus username) and retired engineer. I invented the Holey Moley Digger a vacuum assisted hole digger for digging 6" to 9" holes 10 to 20 feet deep. I designed it for cache tubes. I have been following the site for awhile and love everything I read. I hope my new product can be useful to everyone. It took over 10 years to develop. I have to learn more about the forum and posting but will expand on it as we go. I would be happy to join in on cache tube discussions. I am humbled by the tremendous talent here so want everyone to know I appreciate what you bring together. Let me know if I can help. Regards.
