Inside the Minelab SDC 2300
The Minelab SDC 2300 runs MPF (Multi Period Fast), a pulse induction technology that Minelab says switches rapidly between transmit and receive to reduce interference and improve detection of very small gold. It has two modes: Normal, for a wide range of ground, and Salt, for salt-rich ground such as salt lakes and beaches. Sensitivity runs 1 to 5 in Normal and 1 to 3 in Salt, and there are nine threshold levels. Automatic Ground Tracking follows the ground as you search, after a quick Fast Ground Balance before you start, and Noise Cancel scans automatically for the quietest channel. There is no discrimination and no Target ID: targets come through as continuous audio.
The SDC 2300 ships with the 8 inch round Monoloop coil, SDC wired headphones, a rechargeable 7.4 V / 4200 mAh lithium-ion battery pack and a universal battery charger. Minelab rates the lithium-ion pack at up to 8 hours, and the detector also runs on 4 x C cells. The whole detector, control box and coil, is waterproof to 3 m (10 ft). It weighs 2.3 kg (5.1 lb), extends to 150 cm (59.1 inch), folds to 40 cm (15.7 inch) without disassembly, and Minelab builds it with military-grade materials. Minelab covers the control box and coil for 3 years.
SDC 2300 vs GPX 6000: Which Should You Buy?
Both are Minelab pulse induction gold detectors with automatic ground tracking, no Target ID number and a 3 year warranty. The SDC 2300 is waterproof as a complete detector to 3 m (10 ft) and folds to 40 cm (15.7 inch). The GPX 6000 has coils waterproof to 1 m (3.3 ft) on a splash and rain proof body, collapses to 67 cm (26.5 inch), weighs 2.1 kg (4.6 lb), ships with two coils and takes a third, and puts Bluetooth headphones in the box.
We recommend the SDC 2300 for creeks, wet washes and rain, for trips where pack size matters, and for small gold in tight, mineralized ground where one 8 inch coil does the job. We recommend the GPX 6000 for open ground where larger coils cover more, for salty or noisy patches where its Double-D coil helps, and for long days with wireless audio. Many of our customers run the SDC 2300 as the travel and creek detector and the GPX 6000 as the home-patch detector. For a first gold detector with a target number at 1.25 kg (2.75 lb), see the GOLD MONSTER 2000 in the table below.
SDC 2300, Best For:
- Creek prospectors and wet ground, with the whole detector waterproof to 3 m (10 ft)
- Hikers, fly-in trips and travel, with a folded length of 40 cm (15.7 inch)
- Small gold in mineralized ground, ironstone and bedrock cracks
- Salt lakes and salty ground, using Salt mode
GPX 6000, Best For:
- Prospectors who want pulse induction at 2.1 kg (4.6 lb) for long days
- Open ground, using the larger GPX 14 and GPX 17 coils
- Salty or EMI-heavy patches, using the GPX 14 Double-D noise modes
- Hunters who want Bluetooth wireless audio in the box
MPF, Salt Mode and Ground Tracking in the Field
The SDC 2300 has no discrimination, so iron, foil and lead shot sound off alongside gold. In goldfields that is a trade we accept, because rejecting iron also risks rejecting small nuggets, and we recommend digging every repeatable signal. In mineralized soil and hot rock country, the pulse induction design keeps the threshold steadier than a VLF gold detector, which lets a faint target break through.
Start every session with the Fast Ground Balance, then let Automatic Ground Tracking follow the soil. Normal mode suits most goldfields; switch to Salt mode on salt lakes, salty flats or beaches when Normal will not settle. Pick the highest sensitivity that keeps the threshold smooth, because an erratic threshold hides small targets rather than revealing them. If the detector picks up interference, run Noise Cancel again and let it find a quieter channel.
Where the SDC 2300 Works Best, and Its Limits
The SDC 2300 is at home in mineralized gold country: bedrock cracks, ironstone ground, old workings and tailings, and dry washes. Because the whole detector is waterproof to 3 m (10 ft), it also works creek beds, gravel bars and rain without a cover. For under water use, fit the Minelab waterproof headphones for the SDC 2300. For the rest of the kit, browse our gold detectors and gold prospecting equipment.
The SDC 2300 has limits. With no Target ID and no discrimination, it digs every metal target, so we don't recommend it for coins, relics or beach jewelry; for those, look at the Minelab EQUINOX 900. It ships with one coil, so for covering big open ground the GPX 6000 and its larger coils are the better fit.
Coils and Accessories That Fit the SDC 2300
The SDC 2300 ships with its 8 inch round Monoloop, and replacement 8 inch coil covers are in this collection. For other sizes, Coiltek makes Gold Extreme coils for the SDC 2300: the 10 x 5 inch, the 11 inch and the 14 x 9 inch, with the Gold Extreme Accessory Pack. Check that a coil listing names the SDC 2300 before you buy.
The SDC 2300 collection also holds the SDC 2300 lithium-ion battery pack, a C cell NiMH charger, the universal AC charger and car battery lead, the SDC 2300 carry bag, armrest cover and knuckle protector set, replacement headphones and headphone cable, and the PRO-SONIC wireless audio system, which Minelab lists as compatible with the SDC 2300. Pair the detector with a pinpointer for recovering small targets from rock and gravel.
