This applies to all makes and models and for both red & green lasers.
This laser is not supplied with a detector as standard and so you will need to tick the 'Include Optional Detector' box to add it to your order.

This Fatmax Multiline laser "sets the bar very high" in the field of green beam, cross line laser levels.


Combining accurate & intensely, 4x brighter laser lines in a sleek, ergonomically designed body, this Fatmax model is fast becoming a real "favourite" with the Interior Trades.


Add an optional detector (model LD200G) to increase the usable cross range to 60 metres - its now a very flexible instrument for both indoor & small scale, outdoor site work.


All laser lines are independently switchable and it is site robust too, with all three heads covered with metal shrouds. It has a real quality feel about it.


All in all, its a very versatile & impressive laser level.
