Please Note: Descriptions for each filter are provided below, please select the colour from the options (below).

FT11-R - Red Filter

Red light is generally used for protecting your natural night vision. Used by aircraft personnel, the military and hunters to avoid spooking game, deer and other animals that see very poorly in the red colour spectrum, also ideal for fishing as it attracts young fish and does not reflect off the water surface. The filter is also useful for close range, non-tactical applications such as map reading as it reduces the intensity of light output. However, it is close to an infra-red band so an enemy with a night-vision device has a better chance of seeing the "hot-spot".

FT11-G - Green Filter

Greenlight is especially useful in sharpening outlines. The human eye is most sensitive to the green range of light, it's the brightest of all the colours but this also makes it easier for others to see you. For self-protection it provides an added glare effect and is invisible to wild animals. Greenlight also does not attract insects like white or yellow light does. It is also useful in smoke or fog-filled environments.

FT11-B - Blue Filter

Blue is well suited for use in law enforcement as it increases the visibility of sweat and blood. It also aids in the tracking of animals. But is not as good at protecting your own natural night vision. The filter is also useful for close range, non-tactical applications such as map reading as it reduces the intensity of light output.
