Deep Seeking Detectors

I have a Discovery TF-900 two box detector for deep targets. Also a pulse with a big loop (PVC) but is difficult to use in heavy brush and vines. Has anyone had any luck with a deep seeker detector?

They all advertise they will go down to 5 or 6 feet, but the most I have actually got out of them is about 3 feet on a gallon can. The two box makes a noise with every step, very distracting. The pulse seems to work better, but all in all the old white's I have works good down to three feet with the trigger forced forward (not in the manual).

I'm truly at a loss to understand this rabid desire to find objects at great depths. There's a practical limit to burying an object. Physics and soil dynamics play a huge part in burying an object. As an example, the walls of a trench will, not might, fall in when you get to 6 and a half feet. This is precisely the reason why graves are dug to 6 feet and not 7 feet. Without reinforcement, even a well collapse at that depth. To bury an object at 10 feet, you need to dig a circular hole that is nearly 20 feet in width. Have you any idea how much earth is contained in a cone 10 feet high and 20 feet wide? Probably not.

Stop the insanity. There's not a thing down there at 12 feet worth digging. Everyone who I have ever known with a two box unit has quickly tired of digging junk at 3 feet. Dreamers like you guys are keeping the two box manufacturers afloat.

	There is a place for 2-boxes where over burden or side of a hill (rock slide) MIGHT HAVE OCCURED. Most items were about 2 feet or less,but I really wonder in the south during the civil war how deep did the owners really buried items before they were driven off their land? With all the caches buried during that time (thousands) It's a wonder more caches havent found !!!

I couldn't agree more. If you have a specific item to find, the two box unit can be invaluable. Read the questions we get here about deep detection. They're not looking for a specific item. They intend to roam around the countryside finding objects and digging them up. Go to a metal detector shop and ask the owners why they don't sell second hand two box units. The truth is that those who want to get rid of them are doing so because they are next to useless unless you have a specific target. Only the dreamers buy them and they soon tire of digging up piles of cans or a plow disk at 2 feet in depth. It's truly an old story in the treasure hunting industry.

Any cache buried under duress is going to be hastily buried and sometimes even simply covered over by debris in the area. Other caches are buried with the idea that they should not be visible but accessible a the same time. This conundrum is solved using a variety of methods but deep burial is not one of them.
