More digging

I actually enjoy Archeology. That and fishing are the 2 professions that relax me. Fishing more so actually because you just sit, wait, click. BUT I have no more achievements to get in fishing. Archey however, I do. It's killing me because they're all by chance now. Maybe I'll get a pristine item that I need, but most likely not and I will have to continue my trek to get them.
The first pic is the last 2 achievements I need and the following pic is the items I have left to obtain to complete the 2.

This is sooo hard. Mantid Archeology was not there when Mists launched so what Blizzard did was bring in an item that you can purchase that will only populate Mantid Archeology digsites. The duration is 1 day. I try to use the item when I know I will have free time and not waste it by using the item and only playing for a short amount of time. (I will not tell you what I consider to be a 'short' amount of time...hehe) That item is extremely helpful for the ones that want to complete all the Archeology achievements and don't want to have to dig on sites they've already collected all the artifacts for.

The next item that I buy along with the Mantid Artifact Sonic Locator is the Lorewalker's Map. This randomizes the digsites, BUT you have to pop the Mantid one before you use the Map because it will randomize the site to ONLY Mantid ones. If used before, you've just wasted it and it randomizes the sites to ALL of Pandaria Artifact sites.

"Dags!!! turn around, the artifact is over there!"
