WAVwatch 2.2 vs WAVwatch 2.0

The WAVwatch 2.2 is the newer model and the better pick for most people. It adds 20 frequency sets (166 versus 146), a Good Energy folder, a dedicated Vagus Nerve program, and reworked men's and women's health sets. It also claims improved durability and water resistance and up to 18 hours of battery life. The original WAVwatch is the same core idea with fewer programs, and owners of both report the wristband format and no-connectivity design work the same way. Neither is a medical device, so treat the programs as wellness routines, not treatment.

• Choose the WAVwatch 2.2 if you want the largest program library, the newer health and detox sets, and better water resistance for daily wear.
• Choose the WAVwatch if you already know the 146-set lineup covers what you use and you want the simpler original with its two wristbands and carrying case.
