Thanks Rick(ND) I think I will also, as I said the deal was to good to pass on it so I purchased it the serial number I was told is in the 400s and it still has the threshold knob on the bottom of the control housing on the left side, from my understanding they changed the X5 at some point and removed the threshold adjustment knob for some reason, also read that the first 300 had issues so I am hoping the one I am waiting to be delivered has the issues worked out, I am glad it still has the external threshold adjustment knob, because if the X5 is anything like the other three beep and digs I own the threshold adjustment plays a huge part in how deep they will see targets so I am hoping the X5 is the same with the external threshold adjustment
and yep I do know what you mean by old age, its catching up to me also at 64 its getting harder and harder to get up and down to dig, just cannot do it like I did when I was 20-40 years old and even into my 50s I was still going out every day and digging targets, now I dig a few and set for an hour then dig a few more LOL, went out a couple months ago and dug like 30-40 targets in about and hour and a half to 2 hours and thought I had done myself in, you would think at 64 I would have learned my lessons better but I was on a hot area and the targets were just coming with almost every sweep of the coil so I figured I would get them while I was getting some good finds, I spent the next two days just sitting there because my legs were throbbing wont do that again LOL
