Runner's World Magazine
In August 1999 issue of Runner's World
Magazine rated, Gemini and Phoenix, top of entry-level heart monitors
on page 79. "These easy-on-the-wallet heart-rate monitors
feature simple one- or two-line displays that typically show heart rate, a
clock, day/date calendar, alarm and stopwatch. Some also feature a
target heart-rate zone alarm, which lets you set upper and lower limits
for the heart-rate zone you want to use. The monitor beeps if your
heart rate goes above or below these limits."
Gemini evaluation: "The Gemini is as simple and inexpensive as it gets. It sports a large, one-line display that shows heart rate only. It doesn't have buttons, programs or beeping sounds. We're talking no-frills, minimalist monitoring. But it works."
Phoenix evaluation: "In addition to heart rate, you get a clock, day/date calendar, stopwatch, high/low target-zone alarm and a back light. You'll appreciate the prominence of the heart-rate numbers on the two-line display, and the zone alarm is sufficiently loud."
