Hey all, first time poster so be gentle. Question...I'm sure many of you shoot both indoor and 3D archery. How many of you use separate sight's for each event? I currently have a Sure Loc Challenger with a 4X scope that I'm going to use for indoor, but I was thinking about either purchasing another 3rd axis mounting block for the Sure Loc and buying a stronger scope (thinking about 8X) or just purchasing another Sure Loc so I can just swap them out when needed? I'm concerned about my ranging marks on the Sure Loc tape and also, with the different arrows I use for indoor and 3D. Also, does anyone use the "On Target" software? If you do could you comment on the pro's and con's. Any thoughts?
