From an email press release received 9/1/16.

To help with electrode positioning we have updated a 3d model head with the 10/20 electrode placements. Click the position name e.g. F3, and it will appear on the head. You will still need to translate this to your own head but we hope it helps. (Move the model around with your mouse.)

We are also now selling a version of Go Flow Pro that includes our 1020 position cap instead of the headband. It includes everything you need to get started.
