Wow, tough crowd here. 😀
Truth be told I don't have a good answer to your question. I just got my Excal II delivered and the battery is charging (for around 15 hours more). Watching vids on youtube lots of guys seem to do what I will call gross location with a big machine like the Excal and then use a pin pointer to hone in on just where the object is and that is what I was gonna use it for. But as a secondary use I might also like something with the add on head for what I will call simple location. Often times I know folks who drop something in the water at a dock or on a boat and ask for help locating it, glasses, keys, whatever.
But your question really has made me rethink my need for a pin pointer. I just assumed it was something everybody used to speed things up in locating an object that had just been detected. But I have also seen some vids where they just keep digging, sifting, dumping the sand and run a big detector over the dumped sand till they find the object. And the Excal does have a pinpoint mode, maybe that is enough.
