D70² BI Air Cooled Coil
D70² BI Air Cooled Coil
  • Powerful airflow cooling for temperature control during intense protocols

  • Increased focality and peak magnetic field compared to standard double 70mm coils

  • Practical branding iron coil design for current reversal and ease of positioning

  • Sham version available

  • Compatible with Magstim Rapid² stimulators

The D70² BI Air Cooled Coil has overlapping windings, which create a more focal and higher peak magnetic field compared to standard double 70mm coils. An air extraction unit provides powerful airflow cooling during high-intensity repetitive and theta burst stimulation protocols. The branding iron (BI) design of the coil offers ease of positioning and current reversal via rotation of the coil. This coil has a sham version available.

The D70² BI Air Cooled Coil Sham looks identical to its active version, replicates pulse noise, and delivers a very shallow magnetic field to mimic the sensation of magnetic stimulation.
