Firstly, the XP ORX is lighter. 40 grams less to be exact. The weight loss comes from the lighter shaft. It is injected molded now and all out of plastic. Probably not all that noticeable to swing but it may not end up as sturdy of a machine as the XP Deus.
Another big thing that the ORX lacks is all the frequencies in the new X35 coils for the XP Deus. The Deus can run 35 frequencies on the new X35 coils. The ORX can only handle 21. Xp can go as low as 3.7 Khz. ORX has a low of 13 Khz. Everyone knows he lower the frequency the more depth you can achieve. Will the ORX be as deep as the Deus?? Might need to do some DEUS vs ORX testing to find out!
