Thanks to Hi-Nehm's constant work in it's technology labs, we have a newer, meer advanced, and much smaller and meer convenient poke'dex. It can be used as a watch of a key chain. I'm here to explain the specific uses of the poke'dex so it's easier to use.
1st you'll notice the small touch screen. This is for use of apps which can be downloaded to it. We'll get into that later.
4 small spots, 1 in each corner, serve as a hologram system. This shows not only color of both males and females of the pokemon but different color patterns and variations seen throughout any of the regions. It also shows how they move.
This advantage can also be used to scan berries and tell u exact levels of sweet, bitter, heat, sour, and savory of the berry, if it's ripe, what type of traits it will enhance, if it's best used for block of puffins, which of your pokemon it will be best used with, and which other berries u may want to mix it with along with effects on the pokemon when eaten raw.
