In August 1999 issue of Runner's World Magazine rated Sensor Dynamic's Gemini and Phoenix as the top of entry-level heart monitors.  

"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."
