Add hood trick, combat utility details from video guide
The Health Detection Device is a Boss-grade Plate Armor headgear piece in Crimson Desert. It is a scouting helm integrated with unknown technology. The lenses allow the wearer to see through a target's state, displaying the health of nearby enemies. When equipped and activated, health bars appear above all enemies in range, along with the exact damage dealt by each of your attacks.
This is one of the most useful utility items in the game for players who want precise information during combat. Knowing exactly how much health a boss has left and how much damage each hit deals makes it far easier to plan when to commit, when to heal, and when to switch targets.

The Health Detection Device is found at Marni's Laboratorium in eastern Delesyia. The Laboratorium can be accessed from the waypoint right next to it at any stage of the game.
Inside the Laboratorium, head down the side corridor (not the main hall). Follow the tunnel past a teleporter until you reach the end of the corridor. The helmet is located near a glowing machine at the very end of this path.
Equip the Health Detection Device in your headgear slot.
Open the imbument/function wheel and assign it to the right side.
Toggle the visor up or down using L2+R2. When the visor is down, the detection function is active.
With the visor active, health bars appear above all nearby enemies and damage numbers display with each hit.
One common concern with the Health Detection Device is that it looks bulky and can clash with your character's visual style. However, there is a simple workaround: equip a hood over the helmet. The hood covers the device entirely, so your character still looks cool while the health bar overlay remains fully active. The cloak hood found in a village near Deminus is a popular choice for this trick, and it can even be dyed to match the rest of your outfit.
Seeing actual damage numbers on every attack changes how you approach combat in a fundamental way. Without it, you are guessing whether your build is effective or whether a boss is close to dying. With the device active, you can tell at a glance when an enemy is one hit away from death, which means you stop wasting Stamina on unnecessary attack spam. You also learn exactly how much each skill contributes to your damage, making it far easier to compare Abyss Gears and decide which ones to keep on your weapon.
The device is especially useful during boss fights. When a boss is nearly dead, many players panic and spam attacks, burning through Stamina and leaving themselves vulnerable to counterattacks. With visible health bars, you can see that the boss only needs one more Forward Slash combo and time your finishing hit cleanly instead of overcommitting.
Pick this up as early as possible. Seeing exact enemy health and damage numbers helps you evaluate whether your build is effective and learn boss attack patterns more efficiently.
The Health Detection Device can be found early since the Laboratorium is accessible from the start of the game, though you may need to defeat some mechanical guards at the entrance.
There is no downside to wearing this helmet beyond missing out on other headgear defense stats. Its Defense 6 stat is competitive with most helmets in the game.
This item pairs well with the Marni Laser Helm as a swap option. Use the Health Detection Device to learn a boss's patterns and health pool, then switch to the Marni Laser Helm for burst damage once you know the fight.
