US Patent 7066844 Golf tee

Disclosed is a golf tee having a plurality of stops formed thereon to indicate the depth of penetration of the tee into the ground, the stops being constructed such that the user can sense or feel the first stop that indicates to the user that the tee has been inserted to a desired depth for use with a large club head. The tee, however, can be easily inserted further to a depth marked by a second stop, which positions the tee head at a desired location for a smaller club head.
