Topcon AT-B3 Review.

The Topcon AT-B3 Automatic Level sits in the middle of the new Topcon AT-B Series of Levels. It is described by Topcon as the versitile model for Surveying, Engineering and Construction.

I have been waiting for a while for my new Topcon AT-B3 to arrive for awhile now after ordering the Topcon AT-G3 which was to replace the Topcon AT-G6 I had been using for the past couple of years. I have been working on the A1M D to B site in Yorkshire and decided to upgrade my Auto Level.

The New Topcon AT-B Series.

Topcon have released the new AT-B Series of Automatic Levels. There are three models in the range, the AT-B2 the high precision, the AT-B3 the versitile model and the AT-B4, the cost effective model.
