Gravitator small but powerfull

[Great_Alex]

I use a Gravitator long range locator about 2 year .I test and use it on many archaeological sites and cash hunting , it's very sensitive to gold or silver but :
1. it has some fault signals from non metalic objects like ashes and voids
2. I can't estimate size of object because it has not any signal strenght meter or gravity indicator (the signal of a coin and jar full of coin is the same).
3. no way to estimate depth of target
4. I can't trust results by Gravitator unless i check it by a Lorenz PI detector (it has no way to checking results i must use another device)

5. some times it's very sensitive some times not but always you can test it on sample gold or silver target unlike the other LRLs that i had worked it's realy works no need to ionized gold and ancient target.

why sometimes the gravitator has fault signal and what make fault signal ?
