The KR13 5" DD coil is fully waterproof and suitable for saltwater beach hunting, including wet sand and shallow surf zones. The DD configuration provides stable ground balance in mineralized saltwater environments, reducing false signals from black sand and wet conditions. We've tested this coil in ocean surf and found consistent performance on small gold targets at the waterline. The compact 5-inch size also makes it easier to work around beach obstacles like driftwood and rocks. Browse our selection of wired coils for other waterproof options compatible with your detector.
