A quality 100' tape measure for recording head spacing and for layout of catch cans. The blade is made of fiberglass so it will not rust (trust me, it will get wet). Has readings on both sides of tape for easy use in the field. Tape is extra wide for easy reading in field conditions as well as coated with an abrasion resisitant layer and equipped with a 3:1 gear drive ration (basically, it rolls up 3 times faster than any other tape measurer so you can spend your time doing important stuff)
