BCM for Tradies calls it “the highest warranted and supported laser in its class”.

And no wonder. With a 10‑year warranty, backed by Spot‑on's customer care, and class-leading specifications, the Extreme A3 is a top rotary laser level.

Its automatic motorised levelling system makes for easy setups and great precision. Together with the included wireless remote, you can be setting up grades on dual axes up to 100 m away from the unit with no difficulty, giving you a dependable red laser level that's accurate to within ±1 mm at 30 m.

We've also given the Extreme A3 some extra oomph, some extra spin. By rotating up to 1000 revolutions per minute, and used in conjunction with the included Powerline D5 detector, the laser beam can cover an area up to 800 m in diameter. That's over 2.5 times farther than the average rotary laser, giving an area that is seven times larger.

With its IP65 dust- and water droplet-proof housing, 20‑hour battery life, amazing specs, and big warranty, the Extreme A3 is built for the serious tradie. A durable, powerful rotary laser level for the tough and demanding worksites.
