there is a trend in South Africa at the moment for these hand held weather stations Kestrel 4500.

it has been found that low temp with humidity and higher temp with no humidity have POI shifts that are enough to miss a 40mm kill zone at 50m.

what is your experience in the UK, i know that our weather can change from 25C to 15C in 2 hours so this could have a big effect.

is it worth the tom to be able to know what the weather is doing?

if it will get me one extra shot then it iw worth all the money spent.
