Do not use airtags. If the main lands outside of Bluetooth range of any other iPhones (i.e. In the middle of the woods), it won't work. Look for something with its own independent cellular connection. I personally use JioBit, but most anything marketed as a pet tracker will do the job.

I had my polarized sunglasses before I started jumping,so when it came time to buy an altimeter, I got an Altitrack.

I have a prescription pair of these that I use for both Skydiving and as everyday sunglasses. They are very secure both with and without the nose-piece. They also work well to keep out the wind. Keep in mind you cannot view the LCD screen of a digital altimeter through polarized lenses.
