I scuba/freedive/spearfish quite a lot.
Lately I have seen increasing amount of sharks (bulls , tigers, reef ones) in the Gulf waters, which makes me anxious at times and often disrupts the dives.
As I understand there are wearable gadgets that are supposed to push the sharks away:
ESDS

SharkShield

Did anyone try those in Florida Gulf or Atlantic waters?
Do they really work from your personal experience?
Which one (ESDS vd SharkShield) would you choose?
