Make your own using a 632 nM frequency. I think all these cheap ones use
650/660 which has way lower visibility.Yes, I think it should be a 'dot'
that is 'focussable'.

Answer from the manufacturer is you need the polariser with unit serial
numbers greater than 7300, so the polariser isn't really an optional
extra... The polariser is another £12 +VAT, so getting to be a very
expensive piece of kit.

Should have purchased direct from Skip, www.lasercenteredgefinder.com

There are UK bases commercial laser finders, but they really are
expensive.

There are UK bases commercial laser finders, but they really are
expensive.

Last time I bought kit from the us, the ticket price was half the UK price.
By the time customs and excise had done with me, it cost me more than the
UK price!

Probably a gamble in the buyers favour though.

I did swap notes with Skip over the weekend and he is very customer service
oriented - full marks -
