Our customers can always expect the highest quality

Researchers and clinicians often use MagVenture’s products in combination with products from other manufacturers. Our products are highly integrable with the solutions offered by Localite (neuronavigation), Brain Products (EEG) and Axilum Robotics (TMS Robots)

A butterfly-shaped coil, with static cooling, for highly focused protocols that require higher number of stimuli without external cooling. Equipped with a trigger button on the handle for ease of operation. Designed with a slightly bent surface for best contact with the skull and reduced motor threshold level.
