The Survey tool will spawn and point in the approximate direction of a fragment, there is a light that will indicate the distance you are from a fragment. You can only use this ability when you are inside of a dig site. These dig sites and the objects you dig out are player-specific, you don’t have to worry about competition. But a level 32 player can only see 8 maximum, 4 in Kalimdor and 4 in Eastern Kingdoms and in zones which are between level 25-35. A level 77 player will be able to see 16 dig sites 4 each continent (if his Archaeology skill is high enough). The number of zones and continents you can find dig sites depends on your Archaeology skill and your character level. There are always 4 dig sites per continent, and it won’t change on logout, server restart or anything, you have to dig one out to actually get a new dig site.(The four continents are: Eastern Kingdoms, Kalimdor, Outland and Northrend.) Once you train Archaeology, you will be able to see dig sites on your World Map, they look like little shovels. It’s definately a good idea to level up Archaeology with at least one character. Just imagine your alt hitting level 85 and you can equip right away (keep in mind, these are not Heirlooms, these will not scale with your character level).
However, most of the armors and weapons you can get are bind to account, which is really cool. This profession is mostly for fun, you don’t need to have Archaeology, it’s optional. You won’t gain any real end-game benefits from Archaeology, most of the items you can get have no in-game power like pets, toys and mounts.
This WoW Archaeology guide will try to teach you the basics about this profession. Archaeology is a secondary profession that was released in the the Cataclysm expansion.
