Conductive saltwater reads as a target on basic single-frequency machines, and a rain-rated control box does not survive a roller.

A basic two-tone detector forces a guess on every dig.

The Simplex Ultra runs at 15 kHz, a middle-ground frequency that handles small jewelry, mid-conductive coins, and silver without forcing us to pick between low and high frequency machines. Iron Off, Ground Suppressor, and Coin and Relic ID Scale settings give us tighter discrimination than entry detectors offer, and Frequency Shift gives a clean way to step away from EMI without losing depth. Tone Break, Tone Frequency, and Tone Volume are user-adjustable, so the audio can be shaped to a hunting style instead of accepted as default. Firmware updates over USB keep the platform current as Nokta releases improvements.\u003c\/p\u003e\n\n\u003cfigure\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/11000625_stock__006_7c8b9276-2173-43ed-aec5-14b264a761e8.jpg?v=1725466745\" alt=\"Nokta Simplex Ultra metal detector with carbon fiber shaft, SX28 11-inch DD waterproof coil, and lower shaft assembly\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eBuild, Display, and Audio\u003c\/h2\u003e\n\u003cp\u003eThe fully carbon fiber shaft adjusts from 25 to 52 inches, packs into a small bag, and balances at the cuff with the SX28 coil mounted.

We reach for it when the SX28 is bouncing too much in nail-heavy ground. The SX35 (13.5\" x 12.5\" DD) is the large coil. It adds reach in clean ground for deeper coin and relic targets in open fields and pastures, and we run it where the SX28's depth is the limit, not the ground.\u003c\/p\u003e\n\n\u003cfigure\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/Best_Detector_Guide_Simplex.jpg?v=1767645369\" alt=\"Nokta Simplex Ultra control panel showing target ID, search mode, and 99 Tone audio settings\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Frequency:\u003c\/strong\u003e 15 kHz VLF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSearch Modes:\u003c\/strong\u003e Field, Park, 4 Tone, 99 Tone, Beach, All Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTarget ID:\u003c\/strong\u003e 01-99 (two-digit, with Coin and Relic ID Scale)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 30 levels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 5 levels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGround Balance:\u003c\/strong\u003e Automatic and Manual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNotch Discrimination:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Shift:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIron Off, Ground Suppressor, Threshold (All Metal):\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecovery Speed:\u003c\/strong\u003e Adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTone Break, Tone Frequency, Tone Volume:\u003c\/strong\u003e Adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVibration:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacklight, Keypad Backlight, LED Flashlight:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBluetooth:\u003c\/strong\u003e aptX Low Latency (WHP version, headphones included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSearch Coil:\u003c\/strong\u003e SX28 28 cm \/ 11\" DD waterproof, with cover\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptional Coils:\u003c\/strong\u003e SX24 (9.5\" x 6\" DD), SX35 (13.5\" x 12.5\" DD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft:\u003c\/strong\u003e Fully carbon fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e Graphic LCD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.2 kg (2.6 lbs)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 25\"-52\" adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 2300 mAh Lithium Polymer, approximately 12 hours runtime\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWaterproof Rating:\u003c\/strong\u003e IP68, fully submersible to 5 m (16 ft)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFirmware Updatable:\u003c\/strong\u003e Yes, via USB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 3-year limited manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy the Nokta Simplex Ultra WHP from Serious Detecting\u003c\/h2\u003e\n\u003cp\u003eSerious Detecting is an \u003ca href=\"\/pages\/customer-care__about-us\"\u003eauthorized Nokta dealer\u003c\/a\u003e, and every Simplex Ultra WHP ships with the full 3-year manufacturer warranty registered to the buyer.
