The GEOID HS500 is a chest-strap heart rate monitor at £21.99, eighth in this guide. It clips to a strap around your chest, runs on a replaceable CR2032 battery with no charging involved, and connects over ANT+ and Bluetooth 4.2 to phones, tablets, watches, bike computers and treadmills. The listing gives it 4.1 out of 5 from 1,369 ratings, an IP67 waterproof rating, a wake-up time of under one second and a one-year manufacturer warranty. It also lasts, according to the listing, 800 hours on a single battery.

Two numbers in that same listing are worth reading twice. The spec table gives a Display Size of 0.96 inches, but there is no screen on this device — the only thing that lights up is the flashing LED described in the first bullet, and a chest strap has nowhere to put a 0.96-inch display. The table then lists an Item Weight of 59 g while the third bullet says "Weight with packaging: 56g", so the packaged product is given as lighter than the item inside it. The battery figures have the same problem: 800 hours, and in the same bullet "1 hour a day, 4 times a week, 2.5 years working time". At four hours a week, 800 hours works out at about 3.8 years, so those two figures cannot both be right. One thing does close: the rating breakdown adds up to 100 and averages out at 4.1, exactly the score shown. On sensor type the GEOID is at least honest — it says "Heart Rate Sensor", which is what a chest strap is. Everything on this page comes from the Amazon listing, not from any testing we carried out.

The listing says 800 hours, and in the same bullet says 2.5 years at 1 hour a day, 4 times a week. At four hours a week, 800 hours is about 3.8 years, so the two figures do not agree. The CR2032 battery is replaceable.

**What can the GEOID HS500 connect to?**

Yes. The listing gives it an IP67 rating.
