I don't think any metal detector will go 5' deep. A Schonstedt locator will find it. I have located well casing as deep as 12' with one. You won't want to buy one, they are very expensive but if you can borrow one, it will find the pin. Surveyors use them all the time. Schonstedt Instrument Company: GA-52Cx Magnetic Locator
I bought mine in 1976 and it's still working.
