The Leica BTL5D 5 m Telescopic Level Staff with Bubble 663 131 folds down to a compact and convenient 1 m length and extends out to 5 m for convenience and versatility. This durable aluminum levelling rod has a rectangular cross section to inhibit twisting and turning, so that it stays straight even when unfolded out to its maximum length. This telescoping staff has 5 sections and comes with a carrying bag.
This dual-sided surveying rod is marked off in cm graduations on the front and mm graduations on the back (for measuring internal dimensions). An integrated bubble level makes it easy to ensure that the rod is perfectly perpendicular for accurate measurements.
