I have one on my car key 'bunch', works great for that if I leave them somewhere.
Here from Apple (about the only place we can get them, not sure about the US) they are AUD$45 single, or pack of 4 AUD$149, so buying 4 you get a decent deal, one ' and a bit' free.
Your $ is a lot lower of course, and the US might get better relative pricing too, best check with your local Apple store.
You can get all sorts of mounts, the rubbery ones seem to hold the tags well, urethane onto the drone, or each battery then swap the tag out for changes of batteries.
I guess if you know roughly where the drone went down (find my drone) and you get closer then use the 'find my' app on the i device, you've got a much better chance of locating it.
Even more so if you put a bright white led strobe on it, such as a Firehouse Technology ARCII or similar . . .

These stand out really well in vegetation etc, and at dusk or early darkness they would be really easy to spot through scrub / trees etc.Two
Two things I’ve learned is; 1) crashes are always a possibility, and; 2) recovery is key.
AirData is an essential/critical app for locating your drone in the event of a crash or flyaway. Learn how to use it for rescue and how to access the data for more extensive analysis.
The AirTags are probably the most convenient and cost effective option for GPS. You can’t rely on the Find my Drone function for a number of reasons.
Marco Polo may be more accurate, but it’s bulky to carry with you all the time.
The Firehouse ArcXL is another good product with the automated flashing and audible. PhantomRain wetsuits are always a good idea.
State Farm insures all my drones for $60/year. DJI’s Refresh plan may be worth it for some folks, but it always seemed a bit expensive to me and requires recovery.
Most importantly, you need to consider several risk/recovery factors related to your locale:
Terrain you’re flying over, recovery accessibility - Wooded, water, topography, trails, Leaf cover/season, private property, etc. Are you dressed appropriately for bushwhacking?
Time of day, duration of trip/visit - Do you have time to recover before darkness? Can you return the next day?
GPS/Satellite/Cellular - Are you in an area with good cellular service for a satellite view from your Fly app flight path? Can you upload and access data from AirData and upload to forum for real time assistance?
Take your risk factors into consideration before and during your flights. Fly more cautiously when the risk factors are higher and recovery more challenging. Always have video recording so you can view proxy video for visual keys to location. It also helps to be able to identify trees by leaves as the drone drops through the canopy. Be especially careful of altitude and obstacles during sideways travel/POI’s. Check your RTH and home point settings. Don’t fly over water if you don’t have the PR Rescue Jacket, especially if you’re in a moving watercraft.
I’ve had at least a few challenging recoveries. Most recently, flying over a large river (Potomac), I crashed on an island on the opposite side of the river doing a descending POI. That recovery necessitated driving to a location 3/4 mile upstream, taking my kayak down some class 2 rapids, ferrying across the river to the island, searching for an hour using my paddle as machete, finding it, ferrying 200 yds back to my side of the river, paddling down the C&O Canal to portage point, getting on the bike I dropped off on the way to the put in, biking back upriver to the car, drive back downriver to pick up the kayak.
