{"product":{"id":8289278329116,"title":"Fisher F11 Metal Detector","body_html":"\n\u003cp\u003eThe Fisher F11 Metal Detector is a turn-on-and-go VLF machine built around the same 7.69 kHz platform that put the Fisher F-Series on detectorists' belts for more than a decade. Operating at 2.3 pounds with a 7-inch concentric elliptical waterproof coil and three preset hunt modes, the F11 is the first rung of Fisher's modern hobby lineup, and the lightest, simplest entry point into the entire \u003ca href=\"\/collections\/fisher\"\u003eFisher metal detector lineup\u003c\/a\u003e.

The 7-inch concentric coil keeps the detection footprint narrow enough to separate a clad dime from a pull-tab two inches away, and the Coin mode preset already has the discrimination set up to ignore most iron and foil before we touch a knob. We start in Coin mode, run sensitivity at 4 of 6, and slow the sweep down in heavy-target areas so the audio has time to recover between adjacent signals.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSearch Mode: Coin\u003c\/li\u003e\n  \u003cli\u003eSensitivity: 4 of 6 (drop to 3 near power lines or chain-link fencing)\u003c\/li\u003e\n  \u003cli\u003eVolume: 4 of 6\u003c\/li\u003e\n  \u003cli\u003eCoil: 7-inch stock concentric\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor first-timers, we recommend reading our \u003ca href=\"\/blogs\/detecting-prospecting\/start-metal-detecting-the-right-way-best-beginner-detectors-for-2026\"\u003ebeginner detector guide\u003c\/a\u003e before the first hunt, then sticking with parks until the audio tones become second nature.\u003c\/p\u003e\n\n\u003ch3\u003eTot Lots and Sand Volleyball Courts\u003c\/h3\u003e\n\u003cp\u003eDry sand and wood-chip play areas are forgiving ground, and they hide a steady supply of dropped coins, rings, and earrings.

We give up some target ID precision in exchange for hearing the bent square nails and brass furniture parts that point to a productive corner of the lot. The fixed ground balance is a real limitation in heavily mineralized red dirt, so we save the F11 for sandy and loamy sites and reach for a ground-balanced machine for serious red-dirt relic work.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSearch Mode: Artifact\u003c\/li\u003e\n  \u003cli\u003eSensitivity: 3 of 6 (raise to 4 in clean ground)\u003c\/li\u003e\n  \u003cli\u003eVolume: 4 of 6\u003c\/li\u003e\n  \u003cli\u003eCoil: 7-inch stock concentric, or 11-inch DD for wider ground coverage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnology That Matters on This Detector\u003c\/h2\u003e\n\n\u003ch3\u003e7.69 kHz VLF Single Frequency\u003c\/h3\u003e\n\u003cp\u003eThe F11 runs a single VLF frequency at 7.69 kHz, which is the proven middle-ground frequency for general coin, jewelry, and light relic work. Higher frequencies favor small gold and tiny targets but get noisy in trashy ground, and lower frequencies favor deep silver but quiet down on small jewelry. 7.69 kHz hits the meaty middle, which is exactly what we want in a detector whose primary job is to teach a new detectorist to read targets.\u003c\/p\u003e\n\n\u003ch3\u003e4-Tone Audio With Notch Discrimination\u003c\/h3\u003e\n\u003cp\u003eFour discrete tones (bass, low, medium, high) map cleanly to the 9-segment target categories on the LCD. Iron drops into bass, foil and small gold sit in the low range, nickels and pull-tabs hold the medium tones, and zinc and copper coins ride the high tone. Notch lets us mute any single category we are tired of digging without losing the rest of the spectrum, which is the difference between an enjoyable park hunt and a frustrating one.\u003c\/p\u003e\n\n\u003cfigure\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/f11_08069411-c410-4840-9797-361bb32eb5c9.jpg?v=1692903943\" alt=\"Close-up of the Fisher F11 metal detector control pod showing the LCD with 9-segment target ID, mode and notch buttons, and pinpoint trigger\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eBuild Quality and Ergonomics\u003c\/h2\u003e\n\n\u003ch3\u003eShaft and Balance\u003c\/h3\u003e\n\u003cp\u003eThe F11 uses an S-rod shaft that adjusts from 41 to 51 inches, which fits a 9-year-old at the short setting and a 6-foot-3 adult at full extension. The padded grip and adjustable armrest keep the wrist neutral over a long session, and the 2.3-pound total weight is light enough that our team has handed this machine to detectorists in their seventies without hearing a complaint about fatigue.\u003c\/p\u003e\n\n\u003ch3\u003eControls and Display\u003c\/h3\u003e\n\u003cp\u003eFive face buttons, no menus, no submenus. Power, mode, sensitivity, pinpoint, and notch are the entire interface. The LCD is not backlit, so the F11 is a daylight detector by design, and the control pod is not weatherproof, so we run an aftermarket rain cover when the forecast looks unsettled.\u003c\/p\u003e\n\n\u003ch3\u003eBattery\u003c\/h3\u003e\n\u003cp\u003eOne 9-volt alkaline runs the F11 for 20 to 25 hours of continuous detecting time. Lithium 9V batteries push that closer to the upper end of the range, and rechargeable 9V cells work at the cost of shorter run time per charge. There is no internal rechargeable pack to wear out.\u003c\/p\u003e\n\n\u003ch2\u003eCoil Options\u003c\/h2\u003e\n\n\u003ch3\u003eStock 7-inch Waterproof Concentric\u003c\/h3\u003e\n\u003cp\u003eThe included 7-inch elliptical concentric coil is purpose-built for trashy ground and tight separation. The concentric winding gives a sharper target response than a DD coil at the cost of some depth, which is the right tradeoff in a beginner machine that will spend most of its life in parks and schoolyards.\u003c\/p\u003e\n\n\u003ch3\u003eOptional 11-inch DD Upgrade\u003c\/h3\u003e\n\u003cp\u003eFor open ground, beach hunts, and light relic sites, the \u003ca href=\"\/products\/fisher-11-dd-elliptical-waterproof-coil-for-the-fisher-f11-f22-and-f44\"\u003e11-inch DD elliptical waterproof coil\u003c\/a\u003e drops onto the F11 lower rod and adds noticeable depth and ground coverage per swing.
