Thanks fundooboy and Brihaji.
Brihaji,
Below are the specs of my rangefinder. It has an easy one button operation. You just have to point the rangefinder towards an object and push the button on the top and it will display the distance (yards or meters) to the object. Found it hard to focus my iPhone 5 camera on the rangefinder lens, but some how was able to get a decent shot of how it looks through the range finder. As shown in the pic below, the pink building is 250 yards from my position. Shuts down automatically after few seconds if it senses you are not using it but instantly springs back to life once you press the button. Displays the battery charge level as well.
Let me know if you have any more questions on the rangefinder.
Regarding the groupings, I shot few empty bottles (small bottles) from 10 yards and never missed. Didn't shoot any target sheets as my gun is only 10 shots old. I will wait for it to break-in (after 100 shots) and maybe then I will post the pics of my groupings.
