The DD configuration handles mineralized soil better than concentric designs, making it a solid choice for relic hunting, coin shooting, and beach detecting where ground conditions vary.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNokta SX28 11-inch DD search coil\u003c\/li\u003e\n\u003cli\u003eProtective coil cover\u003c\/li\u003e\n\u003cli\u003eComplete mounting hardware kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy detectorists choose this coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFaster ground coverage: 11-inch sweep width means fewer passes to cover the same area.\u003c\/li\u003e\n\u003cli\u003eDeeper target detection: larger electromagnetic field reaches coins and relics the stock coil misses.\u003c\/li\u003e\n\u003cli\u003eBetter performance in mineralized soil: DD configuration reduces ground interference that causes false signals.\u003c\/li\u003e\n\u003cli\u003eHunt in any weather: fully waterproof construction handles streams, wet sand, and rain without worry.\u003c\/li\u003e\n\u003cli\u003eProtected from the start: included coil cover guards against rocks and debris during aggressive hunting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/17000179_Inline.jpg?v=1779219633\" alt=\"Black DD search coil with 11-inch diameter and attached cable for metal detector\"\u003e\u003c\/figure\u003e\n\u003ch2\u003eWhen to upgrade to the 11-inch coil\u003c\/h2\u003e\n\u003cp\u003eThe larger search pattern makes the SX28 ideal for open areas like fields, parks, and beaches where you want maximum depth and efficiency. In high-trash areas, a smaller coil may offer advantages, but for relic hunting on old homesteads or coin shooting in wide-open spaces, the 11-inch footprint is the right tool. The DD coil shape excels where concentric coils struggle, particularly in iron-rich soil or black sand beaches where mineralization causes standard coils to chatter.\u003c\/p\u003e\n\n\u003cp\u003eWe've used this coil in wet conditions without issue. The waterproof construction lets you hunt shallow water, wet sand after tide changes, and muddy fields after rain. The protective cover that comes in the box is worth using from day one, especially if you hunt rocky ground or dense brush where the coil takes a beating.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation and compatibility\u003c\/h2\u003e\n\u003cp\u003eThe SX28 is a direct replacement coil with no modifications needed.

The larger coil covers more ground during low tide windows when you're racing against the incoming water. Relic hunters use it in open fields where deeper targets like old coins and buttons sit below plow depth. Park hunters find it efficient for covering soccer fields and large grassy areas where targets are spread out.\u003c\/p\u003e","vendor":"Nokta Detection Technologies","product_type":"Coils","created_at":"2023-08-25T10:11:27-04:00","handle":"nokta-sx28-11-waterproof-dd-search-coil-for-simplex-series-metal-detectors","updated_at":"2026-06-03T07:10:13-04:00","published_at":"2023-08-25T10:50:37-04:00","template_suffix":null,"published_scope":"web","tags":"11-inch-coil, beach-detecting, coil-upgrade, coin-shooting, dd-coil, findx-pro, metal-detector-accessory, nokta, relic-hunting, search-coil, simplex-bt, simplex-lite, simplex-ultra, waterproof-coil","variants":[{"id":46509825458460,"product_id":8580881514780,"title":"Default Title","price":"135.99","sku":"17000179","position":1,"compare_at_price":"159.99","fulfillment_service":"manual","inventory_management":"shopify","option1":"Default Title","option2":null,"option3":null,"created_at":"2023-08-25T10:11:27-04:00","updated_at":"2026-06-03T07:10:13-04:00","taxable":true,"barcode":"8699394001797","grams":794,"image_id":null,"weight":1.75,"weight_unit":"lb","requires_shipping":true,"quantity_rule":{"min":1,"max":null,"increment":1},"price_currency":"USD","compare_at_price_currency":"USD","quantity_price_breaks":[]}],"options":[{"id":10836984135964,"product_id":8580881514780,"name":"Title","position":1,"values":["Default Title"]}],"images":[{"id":42262279651612,"product_id":8580881514780,"position":1,"created_at":"2023-08-25T10:12:23-04:00","updated_at":"2023-08-25T10:12:24-04:00","alt":"Nokta SX28 11-inch waterproof DD search coil with protective cover and mounting hardware for Simplex series metal detectors","width":2000,"height":2000,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/17000179_stock.jpg?v=1692972744","variant_ids":[]}],"image":{"id":42262279651612,"product_id":8580881514780,"position":1,"created_at":"2023-08-25T10:12:23-04:00","updated_at":"2023-08-25T10:12:24-04:00","alt":"Nokta SX28 11-inch waterproof DD search coil with protective cover and mounting hardware for Simplex series metal detectors","width":2000,"height":2000,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/17000179_stock.jpg?v=1692972744","variant_ids":[]}}}
