Versatile Automatically accepts a midget head for direct reading of cover under 30mm at very close centres. Ideal for checking pre-cast lintels and pipes. I've tried other cover meters, but the Protovale is my favourite. It's accurate, robust and easy to use. The search range is focussed so there's no problem working near scaffolding, and the audio tone lets you concentrate on the area you're working on.
