I to have the x-5 and the x-8 coil from Sunray,, tell you the truth,,,I like the x-8 much better.. The X-5 coil is a good coil,,, and it separates great,,, But i feel the x-8 does just as good... Plus gets the extra depth,,. I pulled a wheatie at nine inches next to a nail, and it sounded great.... When i opened up the hole and the probe nolled,,, I kept digging and aver i pulled the nail.... I poped out a wheatie... If i was you i would look into a 8 inch... I just like the depth and it covers a little more ground!!!! And to answer your question... I haven't tried the Excelerator but i hear it's just as good,, possibly better!!!!! Good luck on whatever you choose!!!
