Stanley Classic Box Level

This level does everything you want it to do, without fuss, and without making a song and dance about it. Being bright yellow, it shouldn't be hard to find in the back of the shed, or wedged into the van behind the seats.
One thing this level isn't, is budget! Although it may be much cheaper than many, it can still cut it on site with the big boys. The box beam construction means it's plenty strong enough to take a battering, and the magnified vials make it easy to see quickly if you're on the money. No angle vial, but let's face it.
