Faster Swivel

"Barrel can swivel much faster."

- In-game description

 is the first upgrade of Path 3 for the Dartling Gunner in Bloons TD 6. It allows the Dartling Gunner to rotate at twice the speed. For comparison, a Dartling Gunner without Faster Swivel takes up to 2.0s to rotate towards the direct opposite side, but with Faster Swivel it now only takes 1.0s to rotate at the same angle.

It costs $130 on Easy, $150 on Medium, $160 on Hard, and $180 on Impoppable.

Appearance
Faster Swivel adds a tripod for the gun, as well as giving the Dartling Gunner a more rounded helmet.

Summary
While a cheap upgrade, Faster Swivel can be useful in situations where there are multiple sides for the Dartling Gunner to target at, making it useful on simultaneous split-lane maps such as Spring Spring, Pat's Pond, or even Bloody Puddles. In this way, the quicker turning speed allows the Dartling Gunner to quickly target new locations much sooner.

Tips

 * Alone, this upgrade isn't very useful in most situations, but it can be helpful for specific situations where micromanagement around corners is needed.
 * This upgrade pairs well with its further upgrade Powerful Darts.

Trivia

 * Faster Swivel is the cheapest upgrade for the Dartling Gunner out of all generations.
 * Concidentally, the Spike Factory's Long Reach upgrade is also the cheapest upgrade for that tower throughout all generations it appears in. The same upgrade also costs $150 on Medium.
