Frequently Asked Questions

How do I access the programming menu on the G7 BR2 rangefinder?

To access the programming menu on the G7 BR2, press and hold the 'mode' button for approximately five seconds. This will bring up options such as 'Cross-Hair', 'Backlight', and 'Profile Selection'.

What are the essential ballistic parameters to program into the G7 BR2?

Essential parameters include Ballistic Coefficient (Bal Coef), Muzzle Velocity (Muz Velc), Sight Height (Sight Ht), and Zero Range (Zero Rng). You also need to set the Drop Unit to BDC and input Turret Temperature and Altitude for environmental compensation.

How do I select and edit a ballistic profile on the G7 BR2?

First, wake the device and access the programming menu. Select 'Profile Select' and then choose the desired profile (e.g., an empty one like Profile 5). Press the fire button to enter editing mode for that profile.

What is the purpose of the 'Drop Unit' setting on the G7 BR2?

Setting the 'Drop Unit' to 'BDC' (Ballistic Drop Compensation) on the G7 BR2 is crucial. It enables the device to accept and utilize environmental inputs like Altitude and Temperature, which are vital for accurate ballistic calculations at different ranges and conditions.
