When high-tech meets fitness, consumers can be overwhelmed by the latest gadgets and features. For heart-rate monitors, however, the issue is simple: The balance between comfort and accuracy. “I’ve been conducting VO2 Max tests, heart diagnostics for 18 years. The biggest complaint I get from my clients, especially women, is that they hate that chest strap,“ said Richard Diaz, owner of the Diaz Human Performance Centers based in Camarillo, California. Heart-rate monitors without a chest strap aren’t as accurate, though, because they aren't as close to the ticker itself. Still, technological advances have narrowed the gap considerably. While costs can vary from $50 to $500, requiring the consumer to balance desired features with their budget, all models can provide an average heart rate in beats per minute, which is useful for training and fitness measurement over time.

Here is a rundown of some popular wrist-located monitors.

Many are calling this strapless model a game-changer. “The Alpha is a terrific design having sensors under the watch that are identifying how much blood flow is under your skin,“ Diaz said. “It has a unique way of doing it, just by touching a certain part of the device. It does it continuously so you don’t have to stop and gather information.” In a world of increased mobility and convenience, being strapless and Bluetooth- enabled and offering continuous-read data while monitoring standard features such as pace, calories burned and distance traveled, the $199 Alpha is fast becoming a best-seller. “The beauty of the Alpha is that the heart-rate reading is comparatively more accurate than any other (non-chest) monitor on the market,“ Diaz added.

In charting and advancing your personal fitness efforts, the Sportline Solo 965, at just under $100, offers a durable, steady watch that monitors your heart rate with its Any Touch Technology. “We have had it for a while. It has been a good value for our customers," said Tom Connell, senior athletic buyer for the Sport Chalet retail sporting goods chain based in La Canada, California. The 965 model has a Fit Trac memory feature that records resting heart rate over time and shows users how they are improving their fitness condition. It also counts your steps, calories burned and distance covered with a built-in pedometer that also measures speed.

This model offers heart-rate measurement in three formats controlled by a simple fingertip touch. Priced at $90, the Health Touch Plus uses a distance sensor that bases its calculations on the natural swinging motion of the arm. “I prefer the Health Touch Plus because it allows me to be able to obtain data in several different modes about my heart during my workouts, and do it without an annoying chest strap,” said Jeff Bettencourt, a recreational runner from Fremont, California. "The fingertip function provides accurate enough details that I am recommending it to friends."

In addition to providing detailed heart-rate monitoring, it has a compass, altimeter and a bevy of fitness apps. “I prefer more detailed analysis and a lot more features and apps," said Jim Davis of Alameda, California. "The Ambit 2 is the top of the line, and the price is worth it. Great GPS and multisport fitness data details include really solid reads on heart rate with its real-time graphs.”

Long-time jogger Geoff Nathanson of El Segundo, California, likes the SE138 monitor because it’s lightweight and easy to use. "Plus, it is untethered, so I have the freedom to exercise as I want," Nathanson said. "I also like the bonus of the stopwatch and the calorie counter. Overall it's a great product and a regular part of my workout.”
