with struggles and returning (2) sets of loupes back to amazon, i ended up with a another Optivisor with a 2.75 @ 6" magnification. they seem to be good so far.
thanks for all inputs.
surgical or dental; whatever they are called - i did a search and came up null.
i want something better than optivisor of tamiya.
any recommendation?
about "3x" would be good; currents (above) are 2.5x so i might like to go a little stronger.
thanks
