The Vanquish coils work for it as well. I picked up a Vanquish 540 pro pack when they first came out as a backup to my Equinox 800. It is a very capable detector, the pro pack came with the Vx8 and Vx15 coils. Both will work on the Xterra Pro. Selling my Simplex+ and getting the Xterra pro as I have all 3 Equinox 800 coils, a coiltek 10x6, and both coils for the Vanquish. So just for compatibility reasons and continuity of familiarity between detectors I decided to pick up the Xterra Pro and sell the Simplex which has also been a really good detector, but it just makes sense with all the coils and lower rods that will work on the Xterra pro.
