The One Probe allows you to see detailed information about blocks, mobs, and chests all while hovering over them with the probe in hand. You’ll get basic information like what tool will work to break or harvest a block, how far along a crop is in growth, or the power level emitting from a redstone source.

You can get detailed information about what’s contained in a chest simply by hovering while sneaking the wand near it. Now you won’t need to manually open multiple chests just to find one item you may have misplaced.

You’ll also see the potion effects on a mob by sneaking while using the probe. And you’ll be able to see the health of any mob hostile or friendly.

This mod is also very useful for analyzing energy (RF) levels on items from other mods that utilize RF items/blocks.
