Review on ⚙️ ACDelco ARM601-4 1/2” Heavy Duty Digital Torque Wrench: Buzzer & LED Flash - ISO 6789 Standard with Calibration Certificate by Ronnie Saylor

I like the accuracy but the fact that there is no reset makes it difficult to reach the target torque. Go to slow speed and the nut stops and you get static friction, not sliding friction, go to fast speed and you'll miss a few points. The horns kick in slightly earlier, but as this is a pulsed horn the time between pulses is 'no information' and the RPM of the horns is used to report final torque. It takes a few beeps to know they've picked up speed, so plenty of practice learning what to hear is key if you're not seeing a display while vacuuming. A gliding tone that changes frequency/volume and then smoothly with a sudden burst/change in torque setting would be MUCH better, but it doesn't. Usability takes work.
