Double Ranga is the Premium Upgrade for the Boomerang Throwers in BTD4 and BTD5. Whether it's a boomerang, glaive, or lightsabre, the monkey will throw 2 of them with this premium upgrade, meaning that it can pop twice as many bloons as it initially could. It costs 15 in BTD4, 20 in BTD5 and 4800 in Bloons Tower Defense 5 Deluxe.

Tips

The boomerangs target bloons individually, making towers with this perk ideal for guarding forks and parallel paths.
Spamming Bionic Boomers with this premium and the Boomerang Dojo level 3 activated at the same time can win most games with no problems. However, the player should include a Radar Scanner Monkey Village or a Meerkat Spy for Camo detection, or a Spike Factory as another option.

Trivia

There is a design on the boomerangs on the Double Ranga icon in BTD4, which appears to be a kangaroo.
In Bloons TD 5 Mobile, Double Ranga becomes the Tier 4 upgrade for the Boomerang Dojo.
"Ranga" is also a term in Australia for a redhead/ginger (i.e. a person with red hair).
Glaive Lords do not get two more rotating glaives around it.
Even though it says that the Boomerang Throwers learnt to be ambidextrous, the Boomerang Thrower throws the 2 boomerangs with one hand.
- This also applies to other towers, like Bloonjitsu.
