G5 is not your average sight. There's nothing cheap about it. It's construction is top notch. To adjust elevation and windage provided is a 5/32 allen wrench used to loosen (1) bolt and you just move slide. The added light makes it that much better for early morning or evening hunts.
You asked about the floating pin. Based on your FPS you willadhere a yardage stickerthat is dialed in 50 to 90 yards (101 yds if your FPS is 320) for you. This is why it's called smart pin. Just turn your dial all the way up and set your stiker in place. Here's pictures of my G5. I found it hard to get close ups of the G5 on the web when I was searching myself. Hope this helps.
