Purchased this the other day…. I believe a smaller unit would be more helpful.  🙂  Seems to work correctly?  I thought it would be interesting to post.  It is a 1200 ft-lb torque multiplier with a 3/4″ socket.   Weighs around 22 pounds, has a Hardigg case which is written on.  It is pretty cool though and it is also for sale.  I did call around locally and found someone that would calibrate and certify this unit for $350 if you wanted to do that before you purchased it!  LOL  🙂

Just an update but this place also claims to calibrate and A2LA certify this device also?  LINK
