The battery-powered piston has an pressure-disc to dose the mortar at a changeable speed. A full type 100 mortar tube is good for laying approx. 4m of bricks based on 2 tracks (for a 5mm joint and a wall 10cm thick) or approx. 8m of bricks based on 1 track (for a 5mm joint and a wall 5cm thick).
Work freely, no hoses and/or cables
Less weight and dimension and more manageable than Mortar gun 150S
