RE: putting on a sight?
I have the RT900 and RT1000 and they are easy to put on and site..When you put the 900 on just shoot at a bag/block target at about 10 yards with your top pinthis will let you know your horizonal impact and adjust that left or right,then at 10 yards adjust your vertical.On mine the pin holding bar sits about a 1/8th-3/16 above my main site backet then adjust the individual pins from there....
shooting my 20yard pin at 10 yrds hit about 3-4" high...then I went and shot 20yrds and adjusted from there......20-30-40-50...and 60 with my RT1000....
it ony took 24 arrows to get all 5 pins sighted in on the RT1000.....
