This is great as a cheap alternative to an expensive depth gauge. Has mm/inch/fraction button. I use this for checking valve recession on diesel engine heads. As an engine machinist this is a fast digital read out to do quick inspection for estimates.
Nice big numbers to see on the video we do at work for Customers to see
Had this before off the Snap On Dealer but it broke wanted the same one again but he couldnt get them any more they stopped doing them and this works well on the Video we have to do at work is great peace of kit
