Hi,
Hunting for a food cache you stashed a month prior might be tricky at times, especially if you did a good job of hiding it. I saw this ad (no connection) and thought for $25 for a tile you put in with your food, plus reuse after the walk, gives bluetooth range to assist in locating and might avoid a fruitless search.
