Trying to gauge your training intensity or calorie burn without accurate, real-time feedback usually leads to overtraining or wasting effort in the wrong heart rate zone. I strapped this optical sensor onto me forearm, synced it straight to me bike computer, and had spot-on heart rate tracking straight away. The 5-colour LED indicator lights up to show your exact heart rate zone at a glance so you can dial in your pace, the vibration alarm warns you if your heart rate spikes too high, and the dual Bluetooth and ANT+ connectivity pairs seamlessly with over 200 apps like Strava and Zwift. \u003cb\u003eBloody lifesaver!\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003ePrecision optical sensor delivers accurate real-time tracking with an error margin of just ±1 BPM\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVisual 5-colour LED indicator light displays target heart rate zones instantly to optimize training intensity\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDual Bluetooth 5.0 and ANT+ technology syncs with bike computers, smartwatches, and apps including Strava, Zwift, Polar Beat, and Elite HRV\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIntegrated vibration alert triggers immediate warnings when your heart rate exceeds pre-set safety limits\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHeart Rate Variability (HRV) monitoring provides valuable data on recovery rates, strain, and overall cardiac fitness\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSoft, breathable fabric strap adjusts comfortably from 20 cm to 40 cm without pinching or slipping during heavy movement\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIP67 waterproof rating withstands intense sweat, heavy rain, and outdoor cycling conditions\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLightweight 10.6 g sensor casing fits comfortably on the forearm or bicep as a superior alternative to chest straps\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRechargeable lithium battery delivers up to 20 hours of continuous tracking via a quick magnetic charger\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTechnical Specifications\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eType:\u003c\/b\u003e Armband Optical Heart Rate \u0026amp; HRV Sensor\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMaterials:\u003c\/b\u003e High-Grade ABS Sensor Housing with Soft Adjustable Fabric Strap\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSensor Accuracy:\u003c\/b\u003e ±1 BPM (Beats Per Minute)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eConnectivity:\u003c\/b\u003e Bluetooth 5.0 \u0026amp; ANT+ Wireless Protocols\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eWaterproof Rating:\u003c\/b\u003e IP67 Dustproof and Waterproof\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eStrap Adjustment Range:\u003c\/b\u003e 20.0 cm to 40.0 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBattery Life:\u003c\/b\u003e Up to 20 Hours Continuous Operation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePower Supply:\u003c\/b\u003e Rechargeable Lithium Battery (DC 5V Magnetic USB Cable Included)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eOperating Temperature:\u003c\/b\u003e 0°C to 45°C\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSensor Dimensions:\u003c\/b\u003e 3.3 cm x 4.0 cm x 1.0 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSensor Weight:\u003c\/b\u003e 10.6 g\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eColour:\u003c\/b\u003e Black\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eApp Compatibility:\u003c\/b\u003e Strava, Zwift, Polar Beat, Elite HRV, DDP Yoga, and 200+ Fitness Platforms\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e 1 x Heart Rate Armband Sensor Unit, 1 x Adjustable Fabric Strap, 1 x Magnetic Charging Cable, User Manual\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe don't sell crap; we only sell decent products that'll change your life!\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\n\u003c\/div\u003e","brand":"Plain Sense","offers":[{"title":"Default Title","offer_id":44007723466826,"sku":"FT25-CAE107black","price":69.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0721\/7941\/7162\/files\/2025022404091.jpg?v=1785733793","url":"https:\/\/plainsense.shop\/products\/armband-heart-rate-monitor-with-hr-zones-calories-hrm-sensor-for-fitness-cycling","provider":"Plain Sense","version":"1.0","type":"link"}
