How Two Different Prosthetic Arms Help This Repairman

Michael Dunn is an air conditioning repairman. Michael has a body-powered prosthesis and a myo-electric prosthesis. He uses the body-powered prosthesis when he needs to do heavy work like lifting. But when he's in tight space, like someone's attic, he uses the myo-electric, because he doesn't need to move his arm to get the prosthetic device to do what he needs. He also finds it helpful to have two different arms, because if one needs to be sent away to be fixed, he has the other one to rely on. That way he doesn't lose any jobs in the interim.
