The Leica LDT-05 Digital Electronic Theodolite is an economical but advanced instrument for measuring angles and slope, with five-second accuracy for precise measurements, a laser plummet for fast and easy setup, a reticle illuminator for bright views, and other attractive highlights. The Leica LDT-05 Digital Electronic Theodolite measures angles with 5-second accuracy, excellent precision for the most demanding job requirements. The automatic vertical angle compensator, or tilt sensor, which can be switched on or off, ensures accuracy is maintained if your instrument shifts out of balance. If the theodolite shifts out of the compensation range, a tilt warning will display in the vertical angle reading space, helping you avoid costly measurement errors. The LDT-05 theodolite transit also features a laser plummet to aid operators in centering the instrument on top of the control point with ease and accuracy. The horizontal angle indicator, when enabled, will beep when the reading is close to each of the four right-angles, 0, 90, 180 and 270 degrees, assisting with faster orientation. Surveying professionals can measure angles in units of degree, gon, or mil, and set minimum angle readings of 1-second, 5-second or 10-second. With the touch of a button users can set angle readings to 0, and enable the horizontal angle hold.

Both sides of the instrument feature back-lit LCD display panels, enabling construction professionals to access functions from either side, and easily view readings even in low-light conditions. When working in such dimly lit areas, users can switch on the reticle illuminator for consistently clear and brightly lit views of the target. With the Leica 5-Second Theodolite, you never have to worry about running out of power. The NiMH rechargeable battery pack comes standard with the device and takes roughly 3-4 hours to fully charge. The instrument also comes with an AA alkaline battery holder, giving you an additional option should you need backup power. A visual battery power indicator, displayed on the LCD screens, always lets you know how much charge you have left. The optional auto-shut off will turn the unit off after 30 minutes of inactivity, conserving power and saving you money. Rugged and durable, the instrument is resistant against dust, humidity and vibrations, and has an IP54 environmental protection rating.
