Deep Targets With Cache Hunting and Two-Box Metal Detectors – Garrett GTI 2500 Treasure Hound
While this post is not necessarily specific to the Garrett GTI 2500 with Treasure Hound attachment, the Garrett Two Box Unit is one of the most widely used 2 box detectors, and probably one of the best deep seeker/cache hunter units you will buy. You can read more about it here, in our review of the Garrett GTI 2500
The stories and legends abound. The hermit who lived on the edge of town and didn’t believe in banks, the loot from the robbery that was never recovered, and the treasure that pirates hid for the future that still hasn’t been found. Even with the numerous books available on the subject of unfound treasure, there are hundreds and possibly thousands that have yet to be investigated. Treasure magazines and television shows often recount the tales of found treasure, but they rarely show the work leading up to the discovery. There are two very important steps that need to be considered before any treasure hunter reaches the ultimate goal of cataloging and appraising their finds.
Research is the first step in recovering a hidden cache. Hidden treasure stories abound and if they were all true, it would seem that there would be a treasure in each and every backyard. Since this isn’t true, treasure stories need to be listened to carefully and investigated intensely. Local libraries can often provide a lot of the information you are looking for. Old newspaper articles and plat maps are great reference materials. Historical and society journals can also provide background information on the subject and the property that the supposed treasure is buried on. It may be that the property referred to no longer exists, so an exact location will be necessary. A visual inspection of the site can also provide information on where the cache is buried. Most treasures were buried in a place that would be easy for those that hid it to recognize. Large rocks and trees were often used as reference points.
Once a hidden cache has been researched and you have determined that the hidden treasure tale is valid, the recovery of the treasure needs to be considered – the second step in a successful cache retrieval. Dependent on the size of the cache and the probable depth, there are two styles of metal detectors that you can use. A standard metal detector should be used for smaller, shallower treasures and a two-box detector should be used for larger, deeper treasures or when a large area needs to be covered in a short period of time.
A two-box detector like the above motioned Garrett gti 2500 treasure hound can detect treasures much deeper than a standard detector and should almost always be used if your treasure is expected to at least 2 feet deep. Two-box metal detectors are based on the same principal as standard metal detectors, but as the name implies, the transmitter and receiver coils are housed in separate boxes or coils which are then attached by a long rod or shaft. The two-box is carried level to the ground and it is not swept back and forth like a standard metal detector. You simply search an area by walking a grid pattern.
Two-box detectors operate in the all-metal mode and offer no discrimination against unwanted metal. However, because of their design they will not respond to small targets so you are able to pass over unwanted items such as nails, pull tabs, wire, etc. without receiving a signal of their presence which you would need to do using a standard detector and a larger coil.
While two-box detectors are designed to fit a specific niche in the treasure hunting market, they do their intended function extremely well. So if you are interested in trying cache hunting or are into finding old bottle dumps or larger, deeply buried military artifacts, think about getting a Garrett gti 2500 treasure hound two-box unit.
