Greetings, I guess it is time for some advice. I have a new XLT and love it. I am happy also with the 5.3 loop that I just got. I find it works better that the stock loop when searching mostly parks and tot lots. Now,,, here is my question. I know there is a depth gain going with larger loops. Is there a ball park figure I could play with. I am heading on a two week trip to old homesteads in Oregon and Washington. So far I have 6 homesteads with written permission. I want maximum depth. And,,,, White doesn't sell a larger loop for my XLT but does anyone else? If not and there is a significant depth difference, I may just buy an additional detector that is known for good depth. I welcome all comments. Larry
