This Innovo Deluxe is fast and accurate. I'm 70 and a high-altitude and long-distance hiker. On trekking trips (Kilimanjaro, Everest Base Camp, Patagonia, 14-ers), O2 levels are important metrics to consider (at any age). This device fits easily in your pocket or pack and is a reliable and essential companion for personal safety. Others in your trekking party (NEVER TREK ALONE) can use it, too.
