I'm with you on the 1" rule to a point. What I now do, is I carry two pinpointers, currently the Garrett black, and the Garrett orange, reason being, I'm lazy. I have the "carrot" set at max depth, after pinpointing with the detector, getting down on one knee, I can further pin point with the carrot, after digging my plug, if not finding the target, it is often off center somewhere in the hole, with the pointer set at max, I can't tell what side of the hole the target is in, yes, I CAN go through the adjustments to bring down the sen; and then go through the adj's again back to max, but after doing that time and again, it gets old, where as, I instead then switch over to the Garrett "black", and zero in on where or what side of the hole, it's a simple matter for me, and has worked really well. The new pin pointer with iron tone? that in itself could come in very handy I think, more so say like crawling under a porch without a detector or other tight places. Everybody comes to what works best for themselves, I would buy the new one, having the iron tone AND being waterproof, and keep the carrot in my rig for a spare, if someone I'm with should forget theirs or something.
