Guys I am pretty new at this lark but got a bit of a handle on how my new gpx 5000 works after about 7 hit outs. But today I have got to say has been my most frustrating yet!! I have never read or heard of trees giving a strong positive signal but I experienced it today. I thought I was finally on to my first good find deep in a creek bed excavating in, under and around tree roots looking for the elusive target. The tree was starting to look like it was standing on 4 legs with all my undermining and scratching around (4 hrs worth)- the signal seemed to be coming from behind a particularly thick root so I just kept trying to get in behind and under it. Finally I ran the 11" mono all over the roots and trunk even above my head and got the same accursed signal everywhere. It was the tree the whole time. It was a very different tree to the others in the area being a soft scrubwood type in amongst gum and ironbark. Talk about a steep learning curve PHEW! Has anybody experienced this? Any perspectives would be appreciated
