Chest Straps Are Uncomfortable. You Have a Choice.
You know you should train with heart rate zones. It’s the most accurate way to measure effort, track progress, and avoid overtraining.
But chest straps? They’re awful.
They chafe. They slip down. They irritate your skin. They feel tight when you breathe. You spend half your workout adjusting the strap instead of focusing on your form.
There’s a better way.
Meet the GEOID Armband Heart Rate Monitor HS800 from ChetaXpress. It goes on your forearm or upper arm — not your chest. It’s lightweight (11g sensor, 9g armband). It’s comfortable. It stays in place.
And it’s just as accurate as a chest strap (±1 BPM accuracy, 40-220 BPM range).
With Bluetooth and ANT+ connectivity, 45-hour battery life, and magnetic charging, this is the heart rate monitor you’ll actually want to wear.

Why You Should Get the GEOID HS800 — Right Now
Reason 1: Chest Strap Accuracy, Armband Comfort
±1 BPM accuracy is as good as it gets. Professional athletes use chest straps for this level of precision. Now you get the same accuracy — without the discomfort.
Reason 2: 45-Hour Battery Life
Most heart rate monitors last 10-20 hours. The HS800 lasts 45 hours on a single charge. That’s 5-10 weeks of daily workouts. Or one very long ultra-marathon.
Reason 3: Bluetooth & ANT+ – Works with Everything
-
Bluetooth: Connects to your phone, fitness apps (Strava, Zwift, Peloton), and smartwatches
-
ANT+: Connects to Garmin watches, bike computers (Wahoo, Bryton), and gym equipment
One monitor. Two protocols. Unlimited compatibility.
Reason 4: Ultra-Lightweight (20g Total)
The sensor is 11g. The armband is 9g. Total? 20 grams. That’s lighter than two US quarters. You will forget you’re wearing it.
Reason 5: Magnetic Charging
No micro-USB ports to break. No fumbling with cables in the dark. Just snap the magnetic charger onto the sensor. Secure. Simple. Reliable.
Reason 6: Washable Armband
Sweat happens. The armband is washable. Gentle hand wash. Air dry. Good as new.
Reason 7: Perfect for All-Day Wear
Chest straps are for workouts only. The HS800 is comfortable enough to wear all day. Track your heart rate during work, rest, and sleep. Get a complete picture of your cardiovascular health.

Real Customer Story (Early Review)
*”I’ve used chest strap heart rate monitors for years. I hated every single one. They chafe. They slip. I spend more time adjusting than exercising. The GEOID armband is a revelation. It’s comfortable. It stays put. The accuracy matches my old chest strap. And 45-hour battery? I charge it once a month. Never going back to chest straps.”*
— Sarah T., ChetaXpress customer
