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 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.
