- "Identifies enemies and notifies when an enemy is in the crosshair."
- — Create-A-Class description.
When aiming down the sights, the player will suffer from extreme tunnel vision, but in return, enemies will be highlighted in bright red diamonds, similar to using the Chopper Gunner from Call of Duty: Black Ops.
Enemies with the Cold-Blooded perk will not appear with red diamonds through the Target Finder, also, as of one of the more recent patches, the crosshair no longer turns red nor is there any buzzing when an enemy with the perk is highlighted.
Toughness is a good perk to use this optic with; the effects of flinching are far more noticeable when being hit while aiming down the sights and as such, this can throw off the player's aim and make it difficult to engage distant targets. Given the nature of this sight, most players look for the distinct red diamond as an indicator for enemies rather than their body while aiming down the sights, and Toughness will aid greatly in keeping the reticle centered on the marker. The Target Finder is an optimal attachment for light machine guns users.
Hard Wired can be extremely useful in conjunction with the Target Finder, as the EMP Systems Scorestreak or EMP Grenades can knock the optic offline and render it useless. Hard Wired ensures the Target Finder will always function even when a player is affected by an EMP. Also, the mini-map will also be preserved, ensuring the player is always aware of what is happening around them.
- The point of view while aiming down the Target Finder is similar to the Holographic Sight's point of view from Call of Duty 4: Modern Warfare.
- When aiming at a dog from a K9 Unit with the Target Finder equipped, it won't appear with a red diamond. However, the crosshairs will still turn red and buzz.
