The Nokta Simplex Ultra is a waterproof single-frequency VLF detector that punches far above its price with solid depth, clear audio, and a carbon-fiber shaft. It is an outstanding first serious machine and a capable backup for experienced hunters. Nokta built it for beginners, teens, and budget hunters who still want real beach and park performance. Shallow surf, splash zones, sports fields, and backyard hunts are perfect places to learn the hobby on a Simplex Ultra.
