Delta Buoy

Delta Buoy will enable the retrieval of your drone, bow, or other thing that you would rather not lose to the depths! At only 3 ounces (100 grams) it will float 10 pounds out of the water!

No one intends to lost their item in the water but...when you do (and it is when, not if) Delta Buoy will prevent it from sinking to the bottom.
