I recently ordered the HHA sight platform from Wyvern Creations. Today, the weather permitted some outdoor activities other than lawn and garden work, so here we went. After install, I attached a red dot scope and sighted in for 20 yards. During sighting in I used a level to assure bow was not canted during the process. All went well. Moved out to 60 yards, at a different location, and did not have a level. Mistake! I could not seem to get same arrow to have consistent POI. I got down to 4 or 5" from POA. What would those with red dot experience recommend for an attached level for the xbow. I'm sure tomorrow will get tighter results because the level will be available to help keep the xbow more consistent at the shot.
