Minelab SDC 2300 Waterproof Gold Nugget Detector

Minelab SDC 2300 Waterproof PI Gold Nugget Detector 

The Minelab SDC 2300 metal detector is a new model metal detector released in July 2014. The SDC 2300 is making news already due to the compact folding design waterproof to ten feet, and its extreme sensitivity to small gold in very mineralized ground. The SDC 2300 is also quite simple to operate for such a powerful detector, making it a good choice for those not wanting to invest lots of time into becoming proficient with harder to learn detectors. The animation below best illustrates the standout feature of the Minelab SDC 2300 - its ability to quickly fold into a compact package.

The Minelab SDC 2300 is extremely compact, folding down to only 15.7 inches (40.0 cm) by 8.5 inches (21.6 cm) for stowing or packing. It is waterproof to 10 feet (3 meters) and is very rugged, the housing being originally designed to military standards. It is assembly free, needing only to be folded out to full operating length from the compact, stowed position. The Minelab SDC 2300 uses high performance Multi Period Fast (MPF) technology designed to optimize the performance on small gold nuggets and specimen gold. It offers both and audio and visual target response via waterproof speaker, headphones (included), and LED indicator. The SDC 2300 is designed to be easy to use, with an intuitive icon user interface. It operates on only four easily obtained C cell batteries (both alkaline and NiMH rechargeables included) that have no issues with shipping or air travel. The SDC 2300 weighs 5.1 pounds excluding batteries and approximately 5.7 lbs with four NiMH rechargeable C cell batteries.

The Minelab SDC 2300 is fully waterproof and submersible to ten feet but the included headphones must be kept dry, only the cord can be submerged. To get the full use out of the ability to submerge the detector optional waterproof headphones are available. The four C cell batteries are inserted into the end of the SDC 2300 via a waterproof cap visible in the right hand side of the picture below.

The handle mounted LED control panel on the Minelab SDC 2300 is one of the more intriguing features. It is quite small, measuring only about 2" x 3" in size. The LED Indicators show target signal strength, threshold level and battery status. The Audio Control touchpad adjusts the threshold level and low/high audio tone to suit user preference. The Noise Cancel touchpad automatically reduces external electrical interference. Nine LEDs indicate detection signal strength, battery status and threshold level. There is also one Low Battery warning LED. Just behind the control panel is a thumb operated button on top of the handle that engages a quick automatic ground balance sequence. When released the SDC 2300 goes into a continuous slow automatic ground tracking mode.

A recessed control panel on the left side of the SDC 2300 has two rotary switches - the on/off Power Switch, and a Detecting Mode/Sensitivity Control. Both these twist knobs must be lifted and twisted to adjust, making it near impossible for them to be accidently knocked out of position during normal operation. There are two operating modes, Normal Mode, and Salt Mode. The Normal Mode has five sensitivity settings and the Salt Mode has three sensitivity settings.

Normal Mode is for most gold prospecting situations and the default recommended sensitivity setting of 2 is highlighted in green. Areas with low mineralization may allow higher sensitivity settings. Extreme mineralization or electrical interference may require lowering the sensitivity setting.

Salt Mode is for salt flats of salt water beaches. Three sensitivity settings are offered. Only use Salt Mode when Normal Mode will not suffice as it has lower sensitivity to the smallest gold targets. The Salt Mode may also be a setting of last resort in mineralized areas where the lowest Normal Mode setting still does not provide stable operation.

The Minelab SDC 2300 employs a round 8" mono coil that is hardwired to the unit. This allows the coil to be optimized for the best performance possible and eliminates a possible leakage point in the system.
