Sportline has the right idea, combining a pedometer, heart-rate monitor and stopwatch into the Duo 1060. However, user reviews suggest the unit doesn't work as well as it should.
Great idea, iffy application. Wendy Bumgardner of About.com describes the Sportline Duo 1060 as one step closer to the ultimate heart-rate monitor device: "It is a pedometer, speedometer, heart-rate monitor, stopwatch and wristwatch combined." The unit can measure speed and distance without a foot pod, which is unheard of among heart-rate monitors.
The full stopwatch feature is one highlight, plus the watch can record up to 30 intervals and save seven workouts. In interval training mode, a user-defined target heart-rate zone can be assigned to each interval and reviewed along with pedometer data after the workout. The Duo 1060 includes three preset target zones and one custom zone. The watch can't upload data to a computer, however; users are limited to the seven workout memory slots.
While most of the few dozen user reviews we found had positive things to say, a handful of owners are disappointed. One complains: "The watch was quirky from day one. Functions would be difficult to trigger or would not trigger at all." Another reports that the watch filled with water after a run in the "driving rain," although it continued to work once it was cleaned up.
Users in general love the Sportline's finger-pulse feature. Simply touch the face of the heart-rate monitor with the opposite-hand fingertip and the unit gives a heart-rate reading in a few seconds. However, a few say this feature didn't work for them.
Minor quibbles. Owner reviews vary greatly on how intuitive the 1060 is to use. Since experts report no particular challenges, we conclude that the Sportline Duo should be no problem to master for those with previous heart-rate monitor experience. A common complaint is that each feature is found on a different screen, making accessing them time-consuming and distracting while running. Several owners also call the monitor's wristband larger than average.
The Sportline Duo's battery isn't user-replaceable. However, while some manufacturers require monitors to be sent back to them or an authorized service center for battery replacement, the 1060's battery can be replaced by a local jeweler.
Lengthy warranty. With a five-year limited warranty, the Sportline Duo 1060 boasts one of the longest warranties for a heart-rate monitor. Sportline also offers a 30-day money-back guarantee. While there are too few user reviews to give a definitive verdict on the company's customer support, what's available isn't terribly encouraging regarding its helpfulness.
Review Credibility: Good The Sportline Duo 1060 unisex model gets more than 15 user reviews and a rating of 3 stars out of 5 at Amazon.com. Reviewers like the stopwatch features, but often complain of general performance errors such as unresponsive buttons and poor heart-rate readability. The similar Sportline Duo 1060 women's heart-rate monitor attracts a half-dozen additional ratings and a slightly better score.
