Mooger:
The short answer is this: if you're considering the G7, then the only rangefinding bino that is comparable is the new Geovid HD-B.
Here is a quick breakdown as I see it:
Zeiss BRF rangefinding binos
Magnification options: 8x or 10x
Min ranging distance: 10 yards
Max ranging distance: about 1,300 yards
Angle compensation: No
Atmospheric compensation: No
Ballistic compensation: 5 pre-set ballistic profiles effective to 500 yards
Cost: $2,799
Leica Geovid HD (old version)
Magnification options: 8x or 10x
Min ranging distance: 10 yards
Max ranging distance: about 1,500 yards (specs state 1,300 but I have personally ranged to just under 1,500)
Angle compensation: No
Atmospheric compensation: No
Ballistic compensation: No
Cost: $2,399
Swarovski EL-Range
Magnification options: 8x or 10x
Min ranging distance: 33 yards
Max ranging distance: about 1,500 yards
Angle compensation: Yes out to 999 yards
Atmospheric compensation: No
Ballistic compensation: No
Cost: $2,999
Leica Geovid HD-B
Magnification options: 8x or 10x
Min ranging distance: 10 yards
Max ranging distance: about 2,000 yards
Angle compensation: Yes - adjusts real-time from 100 to 1,000 yards
Atmospheric compensation: Yes - adjusts real-time from 100 to 1,000 yards for air temperature and air pressure
Ballistic compensation: Yes - adjust from 100 to 1,000 yards with multiple pre-prgrammed ballistic profiles and also allows the user to input specific ballistic data for a custom solution, with output available in "hold-over" values of inches/cm, MoA or Mil-Rad click values, or equivalent horizontal range for custom turrets. The ballistic calculator was designed by G7.
Cost: $2,995
G7 BR2
Magnification options: 7x
Min ranging distance: ?? yards
Max ranging distance: about 2,000 yards
Angle compensation: Yes - adjusts real-time from ?? to 1,400 yards
Atmospheric compensation: Yes - adjusts real-time from ?? to 1,400 yards for compass heading, air temperature and air pressure and/or programmable for user specified values
Ballistic compensation: Yes - adjust from ?? to 1,400 yards with user specified data for ballistic coefficient, muzzle velocity, sight height, altitude, and temperature allowing for a custom solution.
Cost: $1,599
At the end of the day, the G7 will provide you with about 400 more yards of ballistically compensated shooting distance, with slightly more refined configurable input options, at lower magnification (7x vs. 8x or 10x) and at roughly half the cost of the Leica HD-B's.
I can put you into any of the above rangefinding binos (at great prices) however for the G7 (if you don't know who the dealer is) PM and I will direct you (they aren't a board sponsor so it isn't prudent to give them space here).
Hope that helps.
