acr3764 HemiLight 3 Automatic Survivor Locator Light, Yellow

Great light to add to your PFD. Battery replacement is not possible so be sure to check and keep track of the expiration date on the light. Activation is very quick when exposed to water. The button is only used to deactivate the light. Only way to test the light is to place in water.

This is the same size and function as the Dan Buoy Man Overboard Marker strobe. The Marker is in a vinyl bag which keeps water off of the strobe contacts, but we did as suggested by another reviewer and placed a piece of cloth medical tape over the contacts to reduce the chance of unwanted activation from light moisture, while allowing emersion to soak through the tape and activate the strobe.

The only problem we encountered was if any moisture got on the lights they lit up. hard when you are working at night,, causes night blindness for a bit.

Just sailed the Port Huron to Mackinac Race and need a new emergency light for my PDF. this light is great, small, very bright and attached to my PDF perfectly.

Excellent product and water resistance

As advertized.

I bought three separate batches of this light to be placed on stowed life jackets as required on an inspected towing vessel. The most recently purchased batch from Amazon all had the plastic clips already secured into the body of the light. With such a tight fit these are almost impossible to remove without damaging something. Don't even bother placing these on a crew member on deck as they will activate and use up the battery in almost any rain or spray. ACR's C Strobe is more bulky, but can be purchased in a manually activated version with replaceable batteries as well...far better option than this light.

Like others have said... light comes on too easy and you have to continually shut it off. Great little light other than that tho.

Great device, works well. I'm on a marine search & rescue crew and this is my choice for beacon. Non replaceable battery lasts about 2 years or less depending on use. I do put a small piece of fabric hockey tape over the water sensor. This protects against the strobe turning on accidentally when splashed, but if immersed, soaks through and activates.

Conforme aux descriptions de l'article. J'ai testé la lampe avec de l'eau et ça marche ! Luminosité assez forte à éclats. Par contre, énorme boite pour si petit article; pas très écolo l'emballage !!!!

Lumière puissante comme décrit livraison rapide

Very very sensitive to water. Much more sensitive than my older unit that it replaced. At least I can cancel it.
