Useful for detection of damp patches.
Excellent bit of kit (so hubby says!)Very reasonably priced. We have used to locate damp patches in both caravans and a camper. Seems to be accurate and has pinpointed those areas which need further investigation.Very easy to use, with clear and bright readings. Responds quickly when placed on testing area. Neat and tidy carry case.Definitely a value for money purchase, especially if you're testing before a big outlay purchase.

Works really well
This saved me from a very dubious caravan seller. Well looked after, no damp!!! Got a reading of 70 plus under the front window.

Good value for the price.
I read a lot of negative feedback regarding the quality and accuracy of the readings the meter was giving. Quality wise for the price I would say it is fine. there is nothing bad about this if it is for your own DIY needs. For a business use maybe I would go for a better specced one. As for the accuray, I tested the unit in numerous positions and every time the readings were almost spot on every time. occasionally it was 0.1 to 0.2 percent out. The readings are instantaious so no waiting or struggling to get a reading. The other comments were on poorly lit screen. The screen could not be easier to read and is more than bright enough.

Buying a caravan? You NEED this!
I have been looking for a caravan. Sellers quite rightly do not want people turning up with the 'prong' type testers and making lots of holes. But when shown this, they do not mind.This week I have seen 5 caravans, all being sold with 'no damp' only to be proved absolutely wrong when this finds it. This sub £30 gadget has literally saved me thousands. Damp could not be seen nor smelt, it was hidden inside the caravan walls, yet this found it on all 5 caravans. One had 65% damp in one place on a £12,000 caravan. Even the dealer was impressed and ordered one himself there and then!Seriously simple and brilliant tester. 100% recommended.

Very useful
Used it in my house and caravan.Works fine in my house but it can give false readings when used near fixing points in the caravan.
