Clash of Clans Hidden Tesla - Home Village

The Hidden Tesla is a defensive building with a twist: Similar to a Spring Trap or Bomb, it stays hidden and appears when a ground or air unit gets close, or when 51% of the base is destroyed. However, unlike a Trap, it does not have to be rearmed after being deployed.
The Hidden Tesla is unlocked at Town Hall level 7.
Like Traps, Hidden Teslas are only visible to the player and their clanmates.
A Hidden Tesla has a seven tile range but a six tile trigger radius in which it will only pop up if a troop comes near it or the enemy has destroyed at least 51% of the base.
Hidden Teslas are not traps. Their aesthetics and mechanics trick some into believing that they are traps, but they’re actually defensive buildings like Archer Towers.

Defensive Strategy

The main advantage of the Hidden Tesla is that it is (hopefully) a surprise. Capitalize on that. A well-placed Hidden Tesla can wreak havoc on an attacker’s offensive strategy.
Unfortunately many players design their villages such that it has only as many 2×2 open spaces as it has Hidden Teslas available, which makes it obvious where they are located. Instead, try to make sure that there are a few different places where Hidden Teslas could be lurking.
Be cautious when upgrading the Hidden Tesla as this will reveal its location to future attackers. Combat this by relocating it during the upgrade period.

Before attacking, look for obvious places where a Hidden Tesla might be located and avoid them. Hidden Teslas will only activate when Troops come close to them. If one happens to trigger, keep in mind that it has a low range. If you cannot destroy it easily, avoid deploying more Troops near it if possible, as Hidden Teslas can put out high amounts of damage.
If you see a 2×2 empty square space surrounded by Walls, it is very likely that a Hidden Tesla has been placed there. Be aware that Hidden Teslas are only for Town Hall level 7+.
One Giant and a few Archers can quite easily destroy a Hidden Tesla, as it has relatively low health.
Some people have free places inside walls, but place a Hidden Tesla to deceive the enemy.
