与waila一样，它的目的就是显示准星指向的方块信息，但需要手持物品“检测器No.1”或“创造模式检测器”才能显示（可以通过游戏中的The One Probe Read Me物品调整是否需要检测器才能显示）。
The One Probe (or TOP in short) is a more immersive version of WAILA. You don't get to see the information tooltip all the time but only when you have the probe in your hand (note that this mod can be configured to show the information all the time just like WAILA).
The purpose of this mod is to show on-screen information about the block or entity you are looking at whenever you hold the probe in your hand (or off-hand). The mod itself will show basic information like the name of the block, the mod for the block and also the tool to use for harvesting the block. In addition this mod will also show the amount of RF energy that is stored in the block (if the block supports RF) and if you are sneaking it will also give a list of all items that are in the block if it is an inventory (like a chest).
It can also show information about liquids (default off, you can toggle this on with the 'L' key) and entities. If you sneak this mod will even show you what potion effects are active on the mob.
This mod is very configurable so you can disable all the features mentioned above if they do not fit your playing style or modpack.This mod also has a flexible API that other mods can use to add more information. Deep Resonance will use this mod to show information about the crystals and liquids. RFTools will also have support for this mod.
The One Probe（或简称为TOP）是一个比WAILA（高亮信息拓展）更为拟真的模组。信息提示框只有在你手中拿着检测器时才会显示（也可调整为像WAILA一样一直显示）。
