CTRA BAT Extreme Descender

 BAT Extreme descender, the light of Taiwan, who said that the descenders produced in Taiwan can only imitate foreign countries?
I am very happy to see someone in Taiwan can design his own descender. They are talented! It is
also well designed and can be used left and right, and can be swapped left and right to extend the service life. The friction can be quickly adjusted and locked quickly. It can also be locked easily when using double ropes.

BAT Extreme, like Bat descender but even smoother! When in plain sports mode and without any other friction settings, it has the friction of a regular 8 descender and is able to pass knots such as EDK or alpine butterfly directly, on ropes under 9mm (may need some effort). The bat descender has several ways to adjust friction and makes gradual increase of friction possible, giving more control over the descender and making the rappel experience even more enjoyable. Most canyon descenders use a sharper edge to gain enough friction resulting in need to give rope to the descender (too much friction), or need to place the rope at a certain angle at a certain time to maintain the right friction (too much friction), or just need to grip on tighter (too less friction), or let the rope rub on the waist area for more friction (too less friction). The best friction for rappel is when the rope gets the right friction just from running through the descender, and only needs to loosely grip on the control end of the rope. Since there is no need to give rope to the descender and no need to grip hard on the rope, the control hand is spared from fatigue often seen among long rappels.

The material is 7075 aluminum alloy, CNC cutting and not casting, which is more wear-resistant and durable.
The weight is about 121 grams
