Doing what he is doing, would take all day to measure a load of 30 logs. Who handles 21 ft lumber or 15 ft lumber. I used international scale . Much easier.its all on your measuring stick
It's the US Tape loggers tape. Good for construction as well. I think I have a review video for it on my wood channel Topsaw if you search Topsaw protape review
