    DM78C mini multimeter

    One of the guys in my crew had a DM78C. WOW! What a useful meter to have in your shirt pocket! My tool pouch is full enough without having to carry around a conventional size multimeter while trouble shooting circuits. Anything to make my job easier. The DM78C will be #1 on my fathers day wish list!
