GoTone PRO Now Available: Smart Modes, Forced Cooling and the Next Generation of Portable Strength Training

GoTone PRO Is Now Available

We're excited to announce that the Rayofi GoTone PRO is now available for regular purchase and immediate shipping.

The first production run was offered through a pre-sale, and thanks to the incredible response from our community, it sold out within just one week. We have now completed shipping all pre-orders, and the good news is that the GoTone PRO is officially available for everyone.

The GoTone PRO is the result of more than two years of continuous development, testing and refinement. Every update has been driven by customer feedback and our own experience using the device in daily training.

Smarter Strength Training with Preloaded Smart Modes

Every GoTone PRO ships with the latest Smart Modes already installed.

Unlike traditional cable machines, which provide the same mechanical resistance throughout every repetition, digital resistance allows the GoTone PRO to intelligently adjust how resistance behaves during an exercise.

These modes are completely optional and can be activated whenever they match your training goals.

Constant Speed Mode

Constant Speed Mode keeps the movement speed consistent throughout the exercise.

This helps with:

• Improving exercise technique
• Rehabilitation and controlled movement
• Reducing momentum
• Maintaining consistent repetitions

Eccentric Overload Mode

Research has shown that muscles are capable of producing greater force during the lowering phase of a movement.

Eccentric Overload Mode automatically increases the resistance during the return phase, creating a greater training stimulus without increasing the pulling resistance.

Benefits include:

• Greater strength development
• Improved muscle growth
• More effective resistance training
• Higher training efficiency

Progressive Resistance Mode

Strength naturally changes throughout every movement.

Progressive Resistance Mode gradually increases or decreases resistance during the exercise, better matching natural strength curves for smoother and more effective workouts.

New Forced Cooling System

The GoTone PRO also introduces a new forced cooling system.

The original GoTone already protected itself against excessive temperatures during demanding workouts.

The new integrated cooling fan actively removes heat from the motor and electronics, allowing the device to maintain optimal operating temperatures during longer or more intensive training sessions.

The result is:

• Improved performance during demanding workouts
• Greater consistency at higher resistance levels
• Reduced thermal build-up
• Improved long-term reliability

Why Digital Resistance Is Becoming the Future of Strength Training

Digital resistance is one of the fastest-growing trends in home fitness.

Unlike traditional cable machines, digital systems allow the resistance itself to be controlled by software.

This makes advanced training modes possible, including:

• Constant Speed
• Progressive Resistance
• Eccentric Overload

These are features that conventional cable machines simply cannot provide.

Several companies have introduced digital resistance systems in recent years, including Beyond Voltra, Speediance Gym Monster, Vitruvian Trainer+ and Tonal.

Rayofi shares the same vision of smarter strength training, but with a different focus: creating an ultra-portable solution that can be used almost anywhere—at home, while travelling, in a hotel room, outdoors or even at the office.

Continuous Improvement Through Firmware

One of the biggest advantages of digital resistance is that the hardware continues to improve through software.

That's why Rayofi plans to make the new Smart Modes available to compatible existing GoTone users through a firmware update.

As we continue to develop new features, customers can benefit from ongoing improvements without replacing their device.

The Next Step for Portable Fitness

The GoTone PRO is more than just an upgraded version of the original GoTone.

It represents the next step in portable strength training, combining intelligent resistance control, improved cooling and continuous software development in one compact device.

Whether your goal is building muscle, improving strength, staying fit while travelling or simply making it easier to train consistently, the GoTone PRO has been designed to make high-quality strength training available wherever you are.
