No. CPX is the only good tech field around me and they are 1.5 hours away.
Maintain them properly and/or contact Gog customer service. If you tell us specifically what is wrong with the markers we can help walk you through fixing them. My first suggestion is to replace the batteries in both with fresh Duracell or Energizer. Then, clean the bolts, check all the o-rings for gouges, relube the bolt. Make sure that the regulator is set to a good pressure, not super high or low. Reset the boards and then see if they are working. Try the stock parts too and see if that solves any problems if these steps don't.
I tried doing all of those things and raising the dwell but nothing worked. The extcy leaks internally and the PMR wont cycle completely.
