Airtags plus phone for navigation for blind/vision impaired

I was wondering if anyone who is blind/vision impaired has an iphone 11 or newer and has used airtags as "electronic beacons" to navigate their own property? I am thinking of placing airtags in corners of my property plus my entrance door and mailbox and then use the phone to navigate to those locations? Currently have an older iphone but it's something i'd love to try in the future. Basically trying to find a way to map my property on my phone, also looking into geofencing - any feedback or suggestions would be great! Thank you!
