Never mind - I got a Davis Vantage Pro 2 a couple of days ago :-)
I'll leave the Maplins rain gauge running and compare the 2 rain
readings when we next get rain. Will post the results.

March will be the first full month for comparison, so I'll see how it
goes.

I have a Vantage Pro1 and I think it under recordsa rainfall in general but
without an accurate reference instrument I mave no avaidence to back up my
view which is based on the contour maps published on the Met Office website
and comments by others made here who have simailar equipment. I will
ceratinly be interested to see your findings.

These Vantage pro gauges can be adjustedby altering the height of the screws
under the buckets but it is necessary to know how much the error is before
atempting to do this.
