Anthony Bailey tests the Digital Angle Measurer from the Bosch Professional rangeError loading Partial View script (file: ~/Views/MacroPartials/cwsGalleryImages.cshtml)
Bosch has gained a reputation for devising all manner of professional tools including sophisticated measuring equipment such as this model. The GAM 220 MF is designed to take the stress and inaccuracy out of marking and cutting angles for installation work.
We decided to take a look and see if this device really lives up to its specification.
It's formed from two aluminium extrusions, which are fixed to swivelling aluminium castings at one end. It looks very much like a typical, well turned out short spirit level and indeed it does have two vials with levelling bubbles if, like me, you appreciate working with conventional levelling aids.
However, the lower extrusion incorporates the digital angle measuring aid, which is what this piece of kit relies on. Insert the four AA cells correctly and settle down to read the manual because without it you'll be rather at sea unless you can pick things up intuitively. The red button switches it on, off and clears the reading.
The top button allows you to hold a reading and recall it later when you need it. The bottom right-hand button switches between angle setting modes.
