| Quest type | Side adventure |
|---|---|
| Giver | Robbie |
| Starts in | Hateno Ancient Tech Lab (Purah Pad Research Lab, near Hateno Village) |
| Requirements | Five different monsters registered in the Hyrule Compendium |
| Reward | Sensor + upgrade for the Purah Pad |
Register at least five different monsters in your Hyrule Compendium, then talk to Robbie at the Hateno Ancient Tech Lab. He upgrades the Purah Pad’s sensor so it can track anything you have registered, not only shrines.
The quest unlocks after you finish the Hateno Village Research Lab quest, which gives you the basic Sensor that points toward shrines. Talk to Robbie and ask about the Sensor + to take the job. Any five different monster types count, and you take their photos with the Purah Pad Camera. Registering them once is enough, and there is no time limit or weather condition.
Walkthrough
Register five monsters and report to Robbie
Robbie offers this upgrade once the Hateno Village Research Lab quest is finished. Take photos of monsters with the Camera until at least five different types are listed in the Hyrule Compendium, then return to the lab and talk to him. Hand over the data to start the upgrade.
Search the Compendium with Sensor +
Once Robbie has finished, open Sensor + from the Purah Pad and pick any registered Compendium entry. The sensor reacts more strongly the closer you get to the target, which makes it useful for hunting down materials, treasure and creatures you have registered. The poster on the lab wall explains the controls if you want a reminder.
Rewards
You receive the Sensor + upgrade, which lets you track any item, creature or object registered in the Compendium.
