The Trivenger is a very acurate and easy to thorw boomerang.
The flight is very stable, with a fairly high trajectory. The bommerang brakes very well on the return which allows it to be easily caught, even with a finger.
For a good result in it is imperative to watch tutorials on YouTube for example. https://youtu.be/UGlVkEqy9lY.
