Review on 🚗 Sun Company AltiLINQ - Dashboard Altimeter and Barometer: High-precision Altitude Measurement for Cars and Trucks, 0-15,000 Feet Range by Steve Jones

I think this device will be useful for climbers or serious tourists. I needed something to measure height but didn't know it worked by measuring the change from a known number. So, to measure altitude with this device, you need to enter the starting altitude number. Basically, you need to know the height to use this height gauge. Unfortunately, I didn't realize this until I threw away the packaging, so I can't return it. I just take it as a lesson learned.
