I have both a 3/8s and 1/2 inch digital from Snap-On. They were very expensive but worth their weight in gold when I was working at the stealership for a living. They do in-lbs, ft-lbs, newton meters, and degrees. A lot of the newer stuff says to torque to a certain in-lb or ft-lb and plus a degree. It made it a lot faster being able to use that one tool and when space was limited and you were doing the degrees you could ratchet it and it would remember how many degrees you had turned it.
I would NOT use them on a trail, however, and they rarely even make it out of my shop. I don't loan them to anybody, at all. Not even friends or family. If you come over, I will gladly use it for you and possibly show them to you and how they work. If your lucky I will even let you try them, just once though. After that you have to buy your own. Lol. They were very expensive and made me money when turning wrenches for a living, so in turn they were babied but still were used to complete jobs.
