Amphi Americas is working on a new prototype of their hybrid powered monofin.
Activated by initial body strength and movement, this is two to three times stronger than kicking with a regular monofin.
This upgraded version includes a stronger Thruster and Selector option. When you kick, it activates the motor to push you. The stronger your kick, the more support you will get from the Thruster, like an electric bike.
The Selector controls the amount of thrust support. By pre-programming four different settings of sensitivity, while underwater you can control the thrust power and how much the blade moves with a simple twist of the Selector. A kill switch has also been added to instantly stop the motor in case of an emergency or should you simply want to disable the thrust power.
They are working on a new battery pack as well.
The BETA version will be ready towards the end of 2020 with pricing in the range of US$2,500 (~€2,265). A crowdfunding campaign will be starting soon!
