For a period of time, 4iiii offered both the PRECISION and Podium power meters. The Podium was very similar to the PRECISION, however it featured a rechargeable battery vs. the CR2032 coin cell battery used with the PRECISION. The Podium has been discontinued by 4iiii and they now only offer the 4iiii PRECISION power meter. The current version is called the PRECISION 3+, which features ANT+ and Bluetooth SMART, gets 800 hours of battery life and is accurate to +/- 1.0%.
