Best two box detector?

What is the best two box deep style location detector?
Is there any way to get an infrared image(s) for a site?

The big question is what is the target and how deep?
If it,s a cave or mine, the Discovery TF900 or the older Whites TM800 are best, but if it's a buried treasure target these two along with the whites TM808, Hays, and Fisher Gemini will fill the bill. The newer breed of detectors that mimic GPR and have color displays that show size,dept and shape might be best. Some of the higher power PI units with blanket antennas can cover more territory faster and they go down fairly deep also. Sever government agencies have inferred equipped planes and most likely sats.
