Hoe do you adjust the brigtness of the dot ?
To clarify the P-47 Thunderbolt Gen I is illuminated the Gen II (currently for sale) is not.
The P-47 Thunderbolt has 10 illumination settings to choose from. To access the illumination settings simply depress the On/Off button located on the top of the Ocular lens. Press the button consecutively up to ten times to obtain the brightness that you require. The illumination will turn off after you hit the button for the 11th time. Special note: At any time you can turn the illumination on and off by pressing and holding the On/Off button for 3+ seconds.
