I have a click wernch and a beam wrench. I have hooked them together just to see if the click wrench "clicks" at a particular setting - based on what the beam wrench sez. Found that the click wernch readings are not linear - reads high on the low end and low on the high end. This is based on the beam wrench readings of coarse - and I don't know whether it's any good ether. I perfer to believe my beam wrench - but I don't know why
