Off to Harbor freight, thanks. For those with the old Wixey, pop for the new one, just $30 and it lights up and is easier to read. I always turned my old one off after use, so the battery was OK. But the button batteries are always dead when I want to use the calipers and other devices. I finally got a dial caliper (used at pawn shop) for a couple of bucks, with a nice case, USA made too.
I just don't buy anything that uses button batteries, except for my hearing aids.
BTW, for hearing aids, check out Cosco. Less than half the cost of the same aids from a private dealer, and they have the best hearing test gear around, and adequately trained audiologists. I mentioned getting fitted ear pieces and they gave me oversized transducers (tiny speakers) and a short connector to the aid. Bad choices. Now have longer "wire" and little ear retainers that hold the aid in the ear canal. I mention this because many of us geezers can't hear worth a damn, and even the cheapest of the Costco aids ($1400 a pair) will get you back engaged in life.
The more I do, the less I accomplish.
