It is very helpful to have the Mapper and/or Charge Boots to expedite the process of searching for the crystals. Alternatively, you could use the Mining Hovercraft for transportation, although you will need the Gravity Boots to reach it. A Shield Charger or Tesla Barrier can be used for self-defense (and is particularly useful against Sandflies). It is also recommended to use weapons which take out crowds of enemies, like the Plasma Storm or the Zodiac, but it is not required. To take care of the Desert Dune Monsters, use any powerful weapon, preferably with a Lock-On mod. Any weapon should be able to defeat the Spitting Dune Crawlers, including the OmniWrench 8000 V3, which is able to kill them in one strike. With this in mind, all it takes is patience to get to each area and retrieve the crystals.
Using a pattern
One tactic to speed this up is to be thorough and methodical and to snake around the map following closely to a line starting on one side as you gradually cover the entire desert.
One tactic is to use Visibombs to hunt for the crystals from your ship. Simply look around for one and then smash into it. You can do this as many times as necessary, since you can buy ammo from the nearby vendor. This minimizes the risk of dying when hunting for crystals.
