The 9-inch FMF coil's battery delivers up to 20 hours of runtime per charge, depending on the program and frequency you select. Multi-frequency programs and higher single frequencies consume more power than lower single frequencies. The coil recharges using the XP charging cable included with your Deus II detector. The wireless coil design integrates the battery inside the coil housing, and the 20-hour runtime supports full-day hunting sessions across most programs and frequency selections without needing a mid-hunt recharge.
