Wind meters for sale

I have 4x Orlando Wind Systems wind meters for sale.
These are the clip on style, clip to your existing flag poles.
There are 2x small meters and 2x large meters.
They appear to be in very good condition, I have never used them. They came amongst a heap of stuff that I acquired.
Chasing $150.00 for the 2x small ones.
Chasing $250.00 for the 2x large ones.
Pick up from Brisbane northside, or will post at buyers expense.
