Well, UT has kept groceries on the table for me. I took it up because it was interesting to me, but found in our area there's not alot of level II UT guys. I've kept up my Level II UT, MT, PT and CWI certs. over the years and stay well fed, wife and kids aren't going hungry yet.
Keep looking and Good Luck,
John Wright
PS. Check out Krautkramer NDT Schools in Lewistown, PA., Jim Fauth help me through all the Level II stuff years ago. Great Guy!
