Based on the Tracker LT model, the Tracker LT 2x24 WP has a blue body shell to indicate that it has a higher level of water resistance - IPX5 - compliant with the IEC 60529 standard (jets of water directed at the body from either side do no harm to the device). This model is therefore better suited to any application where there is a higher than normal chance of the unit getting wet. These Yukon Tracker night vision binoculars are compact and lightweight with a functional design that is easy to use and comfortable to hold. The smooth centre focus wheel, raised latching switches and eyepiece focus/diopter adjustment levers make locating and using the controls quick and simple. Twin operational status LEDs illuminate green and red depending on the active features and alert the user should the device be accidently switched or left on. Each Tracker model is fitted with two high grade Gen 1 image intensifier tubes that are colour and gain matched for optimum performance. The wide exit pupil diameter from each ocular negates the need for interpapillary adjustment, which in turn gives a less complicated design and stronger body shell. A contoured one-piece wrap-around eyecup prevents external light intrusion and the permanently attached Eclipse objective lens caps can be rotated and opened right back along the body to prevent loss or obstruction. All models have a built-in IR illuminator while the Tracker Pro 2x24 has a secondary low power wide angle IR illuminator suitable for close quarter illumination in very low light and total darkness. Each has a tactile sure-grip ABS plastic body shell with partial rubber armouring for added protection and hold, a stylish green/black on the Tracker Pro 2x24 and Tracker LT 2x24 but coloured blue/black on the Tracker LT WP 2x24 because of a higher level of water resistance, being waterproof to IPX5. Powered from a single 3v Lithium CR123A battery (not included) and with 2.0x magnification and a wide 30° field of view, they are all individually serial numbered and supplied with a detachable neck strap and a soft carry case.
