hello pine3874. i just bought the 5x8 coil about a month ago. the dealer was friendly and prompt.i tested the coil in the house and all was good. the coil looks great .the cable seems good but not super heavy duty.i did love the price . because of a lot of overtime at work and now the cold,i have not tested it on site as of yet.however i just got permission to hunt a coworkers yard about a short stone throw from chickamauga battlefield! and ill start saving my nickles up for the magic 13 '' .sorry but that is all i have for now
