Full Featured Angle Measuring Digital Electronic Theodolite, The Spectra Precision® DET-2 is a rugged, cost effective theodolite designed to give accurate angle measurements in general construction applications. The affordable, versatile, easy to use instrument and accessories will increase your productivity when turning angles and setting elevations and lines. The DET-2 has a large liquid crystal display on both sides of the instrument with big, easy to read characters. A built-in reticle illuminator and LCD back-lighting can be turned on if needed in low light conditions with a single press of a button. A six-button keypad provides easy access to the most common functions. An optical plummet allows quick setup over a control point. Simple intuitive operation will have your crew in the field being productive without any special training. A 2” accuracy specification along with vertical axis compensation ensures the DET-2 will be accurate enough for your most demanding job requirements. High quality optics and a 30x magnification telescope with a short minimum focus distance provides for clear, sharp viewing at both long and very short distances. Various display modes ensure the operator has the most efficient settings for the job at hand. Angle display readings of 1” or 5” are selectable to meet any operator’s preferences for fast readings. The horizontal angle hold and clockwise or counter clockwise angle measurement can be selected with one touch of a button. Setting the horizontal angle to “0” is also a simple, single press of a button. The vertical angle can be instantly converted to percent of grade. A setup mode allows user customization of the unit. The options include turning the audible tones on or off for right angle notification, units of angle measurement of degree, gon, or mil, and selection of the vertical angle zero position. Basic distance measurement can be easily calculated using the stadia hairs on the telescope. The DET-2 comes equipped with both a NiMH rechargeable battery pack and charger and an alkaline battery pack that utilizes 4 standard AA sized batteries. The rechargeable batteries are efficient and lower operating costs, but the alkaline backup is the perfect solution when there is not enough charge to finish a project. The battery packs have a positive action locking knob for confident, secure fitting on the instrument. Battery strength is indicated on the LCD’s for efficient planning. An automatic shut-off can be selected for higher battery efficiency. The DET-2 has an IP54 environmental rating and is designed to withstand the harsh conditions of the construction jobsite. Each DET-2 comes equipped with a plumb bob, NiMH rechargeable battery pack and charger, alkaline battery pack, adjustment tools, rain hood, multi-language user guide, and a hard-shell carrying case
