How to choose: External or Internal
First, the type: External or Internal. An External tool runs as an overlay on top of the game without touching Squad's process, making it much harder for anti-cheat to detect. If your PC isn't top-tier, External is the way to go, no stuttering, no frame drops.
Internal injects directly into the game process, instant response and more features, but higher load on the system. Ran 15 matches with an internal wallhack and EAC stayed quiet, but you need to follow the basics: don't shoot through solid walls with witnesses watching, don't announce positions you shouldn't know about.
Second, check the feature list. The minimum is Player ESP with HP and distance. Bonus points for Vehicle ESP and World ESP: HABs, rally points, mines. Third, updates. Squad patches frequently; only buy a product with active support and fast fixes.
