Just in case you want to make sure of the levels for yourself, DeWalt offer a manual rotary laser level with a manual levelling system which is operated by adjustment screws. It has a sensor to indicate if the unit has been moved after setting, a side-impact roll cage, and a protected rotary head for durability.

There are two side by side laser diodes in the unit, creating a bright, consistent light.

Maybe it isn't space age technology, but line lasers are a useful piece of kit which allow you to have a consistent, highly visible line across a work surface. It sure beats fiddling around with pencils and little floating bubbles.

DeWalt provide a range of lasers, including their line laser product. It has a self-levelling cross line which is accurate to within 0.3mm, and at a maximum 4 degree angle, along with a built in magnetic pivot bracket for easy mounting to metal surfaces.

Offering a similar style of product to the line laser, DeWalt's tile laser produces two beams of light that cross at 90 degrees for accurate lay out. It has a cast iron body for durability.

The variety of applications that it can be used for are highlighted in a video that can be viewed on DeWalt's website, linked below:

In order to improve safety during drilling, and minimise the risk of mistakes, the Bosch Detector Digital Multiple Finder 10 Zoom locates metal and wooden substructures as well as live and non-live cables.

The product is idiot proof as it has a traffic light style red/green LED display to indicate whether drilling is suitable or not. Voltage is indicated by a high-resolution five segment display and marking a drilling position is straightforward with an intregrated marker.

Providing a manual-level three-beam laser accurate to within 0.3mm/m, DeWalt's Stick Laser has one button operation to make it quick and easy to use.

Other features of the product are a focused laser beam that keeps dots small over long distances, and three precision vials for accuracy on different planes.
