I think it’s broken. replace it. You should be able to find a new one for about $20. I’ve got one that performs similar to yours, accurate but very slow. I replaced it and haven’t thrown it away because I eventually will tear it apart to see what’s in there… Kinda unusual source, but I bought one (then a second) from ALDI last year. Blue LED display easier to see than LCD.
Athlon 10x32 Bionocluars. $40. Not the best optics inn the world.
But for $39.99 – Lifetime warranty, no registration (I think), transferable.
Just right to put in the glove box and forget about till you actually need them.
I’ve got a pair on the way. I’ll let you know what I think.
If you are not a Prime member, get’em direct from the seller Adorama with free (but slow ) shipping.
I’ve used them since way before the Web. Easy to deal with.
If you have prime you can return it and buy it again. They used to adjust prices after the fact within 7 days, but they decided they’d rather pay more than the price difference shipping stuff back and forth. :person_facepalming:
