Used MITSAR 201 and/or 2 medium WaveGuard qEEG caps for SALE
August 2, 2017

I'm selling a used Mitsar 201 (2006 model) that was purchased new by the previous owner in 2008 I believe. Selling for $3000 USD (new units cost ~$7000 USD).

I've used it for qEEG data collection (e.g., NeuroGuide or qEEGPro etc.) without problem. The WinEEG software required for this is free from Mitsar's website. I don't know if you can do full cap neurofeedback/LORETA with it.  

The reason I'm selling is that I've purchased a new NeuroField Q20.

The WinEEG software requires to either be run on a system with Windows XP or on a newer operating system in Windows XP mode. I ran it on a Windows 7 laptop in virtual Windows XP mode. I believe it is free to download virtual Windows XP mode. So there is no need to upgrade any computers or have a computer using Windows XP. Instead, you download a program to use a virtual Windows XP mode within your operating system. .  There are special drivers that Mitsar provided me that I can send to you so you don't have to contact them directly.

ALSO, I'm selling 2 barely used (i.e., one used twice the other used 4-5 times) medium AntNeuro WaveGuard EEG caps . These caps are superior to the standard EEG caps in terms of comfort, quality, ease of use, and cleaning/drying. The reason I'm selling is that I cannot use them with my NeuroField Q20 as there are no A1 and A2 inputs on the Q20 amplifier to allow linked ear reference (it works with Q20 but uses mastoid references). WaveGuard caps work on all other major amplifiers for linked ear references that have inputs on the amplifiers for A1 and A2 (linked ears) such as BrainMaster, Mitsar, Deymed, and Nexus.

These caps are regularly $399 each. I am selling for $275 USD each or $550 USD for both.
