In years of working with / mobilizing Doyle Permenter for troublesome SCR systems and SCR controls, there is no doubt that he is a leader in SCR system and controls : troubleshooting, fault finding, repair, and solutions. To go along with his highly skilled services he compliments them with customer service by answering the phone when you call him or promptly returning voicemail / emails. I highly recommend Doyle Permenter, a must have for your toolbox!
