what screw are you speaking of my friendThe Hogg Father is awesome, perhaps I love the engineering (I have a hoggernaut as well). I had a surelocc 550 which is now up for sale. Love this Hogg Father.
Only 1 complaint/request to Spott Hogg. That is - on the Sureloc you didnt have to look the screw after each adjustment, on the Spot Hoggs you have too - wish they could do it the Sureloc way. But its a small thing as dont adjust often.
the manufacturers intent is to provide a sight that is capable of maintaining tight tolerences in field conditions and last for the rest of your life, mission acomplished there . the only way to truely "sight in " your bow with a movable pin sight is to use a program you would literaly have to provide hundreds of individual tapes to get a sight properly set up they take into account shaft diameter vane length and height arrow weight and length ,velocity, drag ,B.c., so many individual factors I cant rattle them off the top of my head and then kick out the perfect sight tape thats dead on from one foot to 140 yds , i doubt that what ever tape you get with another sight is very accurate and if it was accurate its a one in several thousand shotmy gripe is a common one. sight is awesome very adjustable,. w/that said spott-hogg dosen`t go the extra 1`` to provide sight tapes for diff speed/arrow/wgt etc. hha does as well as others. not much cost to the mfg. aft. U spend 250.00$+ they want U 2 go out and buy a program for another 50.00$+. so if U want one expect 2 spend more $$. but the site is very rugged. high quality typical s.h.
