My wife has a Hoyt Salena. The problem is the sight. It's an HHA. I have the head in the very bottom of the slide, I cant get any more adjustment, at the moment its as low as it can go. Which means she can only shoot at 15 yards. I have the same sight on my V-Tech with no problems. Is there an adapter I can buy to lower it? Or should I look into a new sight?
