First i start to get all shaky and the blood rushes to my head like a thermometer,thought pass through my head of lost gold.Then my feet start to dance like a old Indian war dance like i seen in movies my hands get sweaty and i usually trip in the hole i just dug, fall down face first and the pick myself up this takes some time dust myself off and look around to see if anyone is looking.If there is anyone metal detecting they usually take off i probably looks nuts if you see this happen it just me.Stop and say hello
