For anyone stepping up from a basic single-frequency entry detector, those are the controls that change real hunts: faster recovery clears trashy ground without ghosting good signals, custom tone breaks let the ear separate iron from non-ferrous, and the depth indicator gives a read on how hard a target is sitting before the shovel goes in. All of it lives in a 2.6 lb fully carbon-fiber package rated IP68 to 5 meters, backed by a 3-year manufacturer warranty.

In Park mode the Simplex Ultra runs Recovery Speed at the higher settings so signals separate cleanly between trash, while custom Tone Break drops the iron range to a low grunt and lifts mid and high conductors.

Beach mode retunes the ground filter for conductive sand so the threshold stays usable instead of falsing every step, and the IP68 5-meter rating lets us wade to chest depth without thinking about it.

Auto Ground Balance Tracking adjusts the ground reading on the fly as soil mineralization shifts, with a manual lock available for hot ground. Frequency Shift gives small offsets to walk away from a noisy neighbor or power line.

For trashy iron sites and tight spaces, the SX24 9.5 x 6-inch elliptical tightens the detection cone and improves target separation around nails and brick. For open farm fields and beach grids where coverage matters more than separation, the SX35 13.5 x 12.5-inch DD gives noticeably more ground per swing and adds depth on bigger targets. All three coils are factory-built waterproof units that match the detector's IP68 rating.\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 showing 11 inch DD coil and carbon fiber shaft assembly\"\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, single frequency\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSearch Modes:\u003c\/strong\u003e Field, Park, Beach, All Metal, 4 Tone, 99 Tone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTarget ID:\u003c\/strong\u003e 01-99 with Coin \u0026amp; Relic ID Scale and Target ID Depth indicator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNotch Discrimination:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensitivity Levels:\u003c\/strong\u003e 30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 5 levels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIron Volume:\u003c\/strong\u003e 3 levels and off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGround Balance:\u003c\/strong\u003e Automatic Tracking and Manual\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\u003eFrequency Shift:\u003c\/strong\u003e Yes, for noise reduction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSearch Coil:\u003c\/strong\u003e SX28 Waterproof DD, 28 cm \/ 11 in (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptional Coils:\u003c\/strong\u003e SX24 9.5 x 6 in elliptical, SX35 13.5 x 12.5 in DD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAudio:\u003c\/strong\u003e Built-in speaker, 1\/4 in wired jack, aptX Low Latency Bluetooth, vibration alert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e Graphic LCD with backlight, keypad backlight, LED flashlight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 2300 mAh built-in lithium, USB charging, ~12 hour 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\u003eLength:\u003c\/strong\u003e 25 in collapsed to 52 in extended (adjustable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft:\u003c\/strong\u003e Fully carbon fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.2 kg \/ 2.6 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFirmware:\u003c\/strong\u003e Updatable via USB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 3 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy the Nokta Simplex Ultra from Serious Detecting\u003c\/h2\u003e\n\u003cp\u003eSerious Detecting is a fully \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/customer-care__about-us\"\u003eauthorized Nokta dealer\u003c\/a\u003e, which means every Simplex Ultra ships with the full 3-year manufacturer warranty intact, registered in your name, and supported by a team of working detectorists who hunt the same gear we sell.
