Great question. These sound bird deterrents do not harm birds, as they use recorded bird distress calls to discourage the birds from the area. Think of a warning siren is for people, these sound units act the same way but using recorded bird calls. Laws and regulations very by state, county, and municipality. For this reason we recommend checking with your local wildlife department before purchasing the item.

Bro... I watched the whole video and you can't even give us a sound sample?
You have go turn them on every day sounds like flaw design.
Are there any laws against using these within a marine sanctuary?
