Round. I have a Toxonics Hybrid IV. Talk about sweet. Imagine, clear round pin guard (with a glow in the dark material surrounding it so it will glow in low light conditions), all metal construction (for durability), built in bubble level indicator (to help you get the best tune-ups and performance out of your bow), fiber optic pins (for shooting low light conditions), great looks (for showing your bow off to all the guys), very reputable company (something to brag about), and a VERY reasonable price (59.99 so you will have money left over to put into other things for your bow).

I have just taken a couple pictures of my sight to show you what it looks like.

Here are a couple pictures of the sight in the light to show you what it looks like overall and to show you the camoflauge.






And, here are a couple pictures of the sight, with all the lights off, after being in the light. Talk about sweet. Carry a flashlight with you, shine this thing up, and you could be shooting your bow at mid-night. (P.S. I am not suggesting that anyone poach deer at night, it was just a statement to show how bright the sight is)




The pictures are a little fuzzy, thanks to my piece of junk digital camera. It has seen its day. It is a Kodak DC-120, and this thing is getting pretty old.

Hope you enjoy the pics.
