In the hottest of soils, best to use 18 khz and either 3 or 4 reactivity with silencer at -1. And dig all nonferrous readings. Deus one of the best VLFs for hot soil. Granted you will still be depth limited, but 6 or 7 inches deep in hot soil is actually very good from a VLF perspective. Many other machines will start signaling nonferrous targets starting at 5 inches as iron vs nonferrous when using discrimination.
And with the Deus you get the great separation/unmasking to boot.
