White's TDI SL 12 Metal Detector
with 12" Dual Field Search Coil

PulseScan TDI SL 12 was developed to provide serious detectorists a piece of equipment that was not simply a "re-hash" of existing technology in a new housing. Initially developed to meet the demands of gold prospectors searching for both extremely small and extremely deep nuggets, the TDI has evolved into a detector that has proven itself as an effective detector for relic hunting, beach hunting and, under the right conditions, even coin hunting.

TDI is fairly simple to operate, the subtle nuances will make you successful under different conditions. White’s has an excellent instructional video on their website on how to operate the TDI. As well-known detectorist and prospector Steve Hersbach says, "The bottom line - the worse the ground mineral conditions get, the better this machine will fare compared to a VLF unit."

The PulseScan TDI SL 12 lists for $1,299.95 which includes the 12" Dual Scan coil, one Lithium Ion rechargeable battery pack and the standard White’s two-year transferable warranty. A 7.5” Dual Scan coil is available and additional coils and accessories are in the works to further expand the versatility of the TDI.

TDI what a great machine!

Review by Dennis P on February 16, 2015

I bought my TDI in September of 2014. I use this machine to hunt wet sand on beaches for coins and jewelry and it is awesome for deep finds and mineralized wet sand. WARNING!!! It finds everything made of metal!! It's not uncommon to fine a bobby pin at 18 inches. But...that could have been a gold ring too! I use the "HIGH" setting in parks to look for coins and it finds silver very well. Many quarters and dimes and some medium sized rings but not many pennies at that setting and very little iron or pull tabs. It is a high producer in heavily trashed ground. Where it really shines is when I prospect for gold nuggets. I've found several here in Oregon and it has no problem in tailings and mineralized ground. It's light weight and extreme sensitivity make this a real go getter of a metal detector.
