That's my plan as well. I have a Nox that I'll use around foundations, trashy areas and a PI for open areas. 

Thanks everyone for your input. I’m leaning towards a 4500. Probably a used one as a new one is out of my reach price wise...

I'm killing myself trying to determine the best rout to go with PI detector. I just moved to Tennessee and with red clay mineralized soil would the White's TDI SL be a good choice or the Garrett ATX? I am new to PI detecting and thinking the TDI would be a good beginner's but should I jump all in with the ATX? I've heard the TDI is under powered but the ATX has a steep learning curve. 

Your input is welcome!!!!
