The SMARTractor by Acoustical Systems comes with five tangential curves combined on the same protractor. It is made from a mirrored acrylic foil supplied by Evonik. It is 3 mm thick, i.e. the same thickness as a 180 g LP.

The SMARTractor will help you achieve a precise, easy and quick alignment. It is easy to use with 1-point fixed setting for each tangential curve. All alignment lines are laser-cut hairlines (0.05 mm). It incorporates a real glass magnifier in an aluminium frame. This makes for unrivalled precise view when aligning your stylus. All 5 tangential alignments are based on true triangular positioning, which enables independent measurement of the tonearm's effective length. It makes it fully universal! It is thus compatible with ALL pivot tonearms, irrespective of their effective length or mounting position.

It is very easy and fast to use and delivers unrivalled reading and an amazing musical result. The ultimate must as far as alignment protractors go! Recommended for all amateur and professional perfectionists and to all those of you who own a high-end tonearm and cartridge.
