Single Intuitive Control (SIC)
The operation is simple and intuitive. The idea is revolutionary. The system rests in the OFF position or SLEEP mode. The first press of the SIC button puts the system into AUTOMATIC mode. In this mode, the LED automatically adjusts to the ambient light conditions using the Target Light Sensor Technology. The second press of the button puts the system in MANUAL mode. It starts at the brightest day setting and cycles through ten (10) day and three (3) night vision settings with every press of the SIC button. Holding the SIC button for more than three (3) seconds puts the system back to SLEEP mode, conserving battery life. Hitting the button again puts it back into AUTOMATIC mode. Simple. Intuitive. Effective.
Target Light Sensor Technology
Through extensive R&D, we’ve discovered that mounting a sensor in the light path behind the objective lens magnifies the incoming light and provides greater accuracy of the target light levels. In AUTOMATIC mode, this key feature allows the BCO reticle to be properly illuminated even when the user and target are in dissimilar light and avoids sensor errors caused from ambient light. More importantly, as an operator is on the move, the BCO will continuously adjust automatically. For example, light levels can vary extremely from streets to dark alleys and buildings. In today’s urban warfare, when a nanosecond can make a difference, there’s no time to search for a poorly illuminated reticle or make manual illumination adjustments.
The BCO Microcontroller is the brain of the operating system. Its custom program reliably and easily controls all of the electronic features. Unique to the industry, the BCO microcontroller is capable of being re-flashed with alternative programs via a sealed flash port on the back of the battery housing. This port can also be used to attach accessories such as a momentary remote tape switch.
Vibration Motion Sensor
The vibration motion sensor conserves precious battery life by putting the electronics in SLEEP mode if motion is not detected after two hours. Additionally, if the SIC button is accidentally depressed in a carrying case or storage rack, the system automatically turns off after three (3) seconds. The BCO has an average battery usage life of 2000hrs. with a minimum of 775hrs. on max brightness. In SLEEP mode, the battery will maintain the full 10 year life expectancy of a Surefire Lithium 123A battery.
Housing Designed to Accept Accessories
Versatility is at the forefront of the BCO housing design. So you’ll find multiple areas for mounting “add-on” accessories. For starters, the OD of the eye-housing is a machined 30mm diameter surface with a 2mm groove for locking on dust covers or an assortment of other accessories. Plus, two mounting bosses are placed on top of the housing for attaching additional accessories. On the objective end, we added a 42mm x 3mm OD groove and threaded the ID for added versatility for accessories, such as anti-reflection devices, dust covers, and/or laser filters.
