"At Cocos Island the currents can be wild. I surfaced over 100 yards away from the pickup Zodiac. One blast from my Dive-Alert and they saw me. It's simply attached, effective and could be a life saver. I wouldn't leave home without it." -Stan Waterman / Underwater Cinematographer

"...a crocodile or by a horde of mosquitoes. With Dive-Alert the tender quickly found me
and turned what could have been an all-night stay in a Raja Ampat mangrove swamp into a non-issue!"

Love this attachment. I havent seen anything better to get help. Be carful of which one you buy. Different BCs are not all created the same and will require one of three different Dive Alert that will fit your respective BC.

Rating: Great!!
Reviewer: Daniel A.
Working for a dive operation in Brazil I always carry my divealert. I only had to use it once, when the current shifted and took me and a novice diver farther out into the ocean. The skipper immediately heard the whistle and promptly arranged for our pick up. A must with a deco marker for ocean diving.

Rating: Dont get caught w/o it
Reviewer: Scott Michael  -  View all my reviews
I never dive in open ocean without a dive alert. I needed another one so I bought it. Just make sure not to test it without covering the horn with your hand unless you want to hack off everyone in the dive boat. The output is LOUD and can damage your hearing. If you have to use it in the water I would suggest covering the ear nearest to it.

Rating: Hope I never need it but...
Reviewer: Scott Michael  -  View all my reviews
I had one of these for my old inflator. When I switched to a ScubaPro Air2, I decided to upgrade to a Dive Alert Plus with a Type III connector. You can read my negative review of that device elsewhere. I returned it and purchased a standard Dive Alert with a type III connector. Just remember to always rinse it out after using it in salt water and when you blow the water out of it after rinsing, PLEASE for the sake of your ears and those around you, keep your palm over the bell of the horn. I accidentally hit it before a dive in St. Lucia last month and my ears are still ringing.

Required by most Capt.s, seems pricey when a Storm whistle works very well.

I found the Dive Alert to be a great purchase. It is one of those things that you hope you will never have to use but is comforting to know you have it. It is extremely loud so do not point is at anyone when you activate it.

Rating: dive alert standard
Reviewer: joel tobey  -  View all my reviews
The dive alert was shipped in a timely manner. The next weekend I took it on a dive to try it out. It did all that was said in the advertisement for the product. It was so loud my dive buddy told me not to use it again unless I had to that the sound would hurt her ears. I do alot of ocean diving and after seeing the movie "Open Water" I decided that this was necessary for ocean diving with dive groups as I never want to be left behind.

  • craig:

    Does this also work underwater?

    Darrick  (Certified Scuba Instructor at

    Hello Craig, yes this is above water signaling device only. The V.2 is the under/above water signaling device.

  • Jason:

    I have a Sherwood Avid BC. Am I ok with the Standard unit? Thank you.

    Bill  (Certified Scuba Instructor at

    Yes the standard will fit.

  • Jantina:

    I have a : LaZer Scuba BC for Women (zeagle) and need a dive alert little unit. I found that mine does not fit this unit ..totally different hose connections. I have a dive-alert plus. Which one do I need?

    Darrick  (Certified Scuba Instructor at

    Hello Jantina, if you have a standard power inflator you will need a type I. If you have the octo/power inflator all in one unit then you will need the type II or III. Depends on which one you own. If you own the the Zeagle octo + then it is a type II. If you have the octo-Z then you need the type III.

  • Curt:

    I dont own my on bc. I rent them. Which Dive Alert should I buy?

    Bob  (Certified Scuba Instructor at

    Typically the Type I will fit most standard Low Pressure Inflators.

  • Txdiver:

    Which device do i need for zena zip vest BC and oceanic regulator ?

    Bob  (Certified Scuba Instructor at

    If the bcd is using a standard Power Inflator )as opposed to an inflatable octo) Type I would be the choice.

DiveAlert is a specially designed, small, light weight air horn that uses quick-connect / disconnect hose couplings to become an integrated part of your power inflator and buoyancy compensator. Installation is easy and only takes a moment.

DiveAlert uses a small amount of air from your SCUBA tank to make a piercingly loud sound. People have been able to hear a DiveAlert one mile away from a diver in need. In conditions where visibility is limited, a DiveAlert can be a life saver.

After each use, your DiveAlert should be pressurized and rinsed with fresh water with the rest of your gear. Make sure that before every dive you check that DiveAlert is installed correctly and functioning properly. When testing, be careful not to point DiveAlert toward yourself or toward anyone else or loss of hearing could result.

DiveAlert does not require any modification to your equipment, and it does not interfere with the normal operation of your equipment. The DiveAlert comes in three different models to accommodate different connectors: DA1, DA2, and DA3.

Simply press the orange button to create a piercingly loud sound. Do not point the DiveAlert towards anyone, as it could cause hearing damage. It is that loud.

The DiveAlert uses chrome-plated brass couplings to attach to your power inflator. The activator button engages a chrome-plated brass actuator valve stem causing a small amount of air to rush by a stainless steel diaphragm, emitting a piercingly loud sound from the injection-molded thermoplastic body.

"On Saturday July 11 I was diving Barracuda reef in Cozumel. The only other diver with me was the dive master from a local dive operation. The current that morning was in excess of 3 knots. Our depth averaged around 90 feet. After surfacing from the 55 min dive we found that the boat was not there. As we continued to be swept further to the north I realized we would be here for awhile. I inflated my sausage and used it for water wings. I put the snorkel I carry in my bc in my mouth to save my remaining air. After the second hour of floating I began to notice the mast of a sail boat far off in the northern direction. It was difficult to see because the swell was picking up and the waves from the chop prevented me from looking in that direction for very long. About 45 minutes later I realized the boat was definitely traveling in our direction. As it approached within 400 feet of us I realized they did not see us. The dive master was whistling and waving his arms frantically but the crew still did not see us. I raised my DiveAlert, plugged my ear and gave a blast. I watched their heads turn and look in our direction and the front sail being retracted. After a few minutes we were on the boat. If it weren’t for the DiveAlert we would have had to spend even more time being swept away. The dive shop said he was 15 minutes from alerting the harbor and they would have had to launch the helicopter.
FYI: I was certified in 1976 and have carried the DiveAlert with me on hundreds of dives. I saw it advertised in the DAN magazine and purchased it immediately. Thanks for having such a great product. Don’t go diving without it!" - Terry B.

"Forty minutes had passed, after dropping two divers in the water off a small island in Washington State, the first diver returned as planned. The boat pick up was simple, but where was her dive buddy? In this case, the recovered buddy was a photographer with a very small focus on keeping track of her dive companion. The scenario, often felt by dive boat operators, now takes place. Where is the other diver? Is the missing diver still underwater or is the diver somewhere on the surface waiting to be picked up? Does the boat and operator leave the dive site and expand the search outside the designated area? With currents and eddys, decisions are made more difficult. With a small surface chop, sighting a diver is tough. One hour after the divers had entered the water the search was expanded outside the designated dive site. An additional forty-five minutes had passed before the diver was found safely drifting in the shipping lanes between the U.S. and Canada, over one mile away. It turns out that upon her initial descent, she was unable to clear her ears but spent several minutes trying. When she finally succeeded in clearing her ears, and again attempted her decent, she had drifted off the reef and into much deeper water. Consequently, she returned to the surface and tried signaling the boat with her whistle but found it impossible, chin deep in water with seas hitting her in the face. The dive boat remained at the dive site as she drifted farther away. This turns out to be a classic example of necessity inspiring invention. How could this diver have signaled the boat more effectively? Certainly a signal tube (safety sausage) would have been an asset. But, a signal tube takes time to deploy and if the diver is in distress, sometimes impossible. The signal tube also requires surface support to look and see. However, with any remaining air inside the diver’s cylinder, there is a reliable power source. Why not tap into this power source by means of quick connect/disconnect hose couplings found on all buoyancy compensators?! The DiveAlert was born. Many professionals and dive operations around the world have embraced DiveAlert. The Pacific Aggressor Fleet, Peter Hughes Diving and Nautilus Explorer, to name just a few, now require DiveAlerts on their diving guests. These operations realize that most incidences occur at the surface and Dive-Alert provides them additional peace of mind for facilitating surface assistance. Since the introduction of DiveAlert, Ideations, the U.S. manufacturer, has received numerous letters recounting near fatal incidents that have been averted because they had a DiveAlert. One diver wrote to tell his story of signaling the aircraft carrier, USS Eisenhower off Jacksonville, FL with his DiveAlert and credits it for saving his life. This story was later reenacted on the Discovery Channel’s, “Storm Watch” for the national TV audience. Another diver wrote that a fluke series of events brought a boat’s propeller down on top of him. His only viable means of signaling for help was his DiveAlert. The DiveAlert is a powerful little tool. It is intentionally very loud and the manufacturer recommends that the diver simply tip his or her head back in the water so as to immerse the ears, thus making activation infinitely more comfortable. DiveAlert is a piece of insurance, which makes diving safer and more fun. DiveAlert is sold exclusively through dive stores worldwide." -DiveAlert Article for Immersed Magazine

"Surfacing at 2:00 PM from a dive that started in 10-15 knot winds and 3-5 foot seas, I found myself in 30-35 knot winds and rapidly building 8-foot seas. It took about 30 seconds to see the boat that had, just moments before circling above me. I continued to beep the DiveAlert in the position I had seen the boat. I inflated my BC and put my lift bag on the end of a six foot pole spear to use as a signal flag. After about 30 minutes of this I dropped my weight belt and turned off my tank to conserve the 200 pounds of air I had left until I could use it to signal a passing boat. 24 hours later the passing boat I used to signal was the USS Eisenhower! Underway at 25 knots, sailor Airman Williams on the flight deck heard me, turned and saw me just 50 feet off the port side blasting my DiveAlert and waving my makeshift flag. I was rescued by the US Coast Guard, the US navy and the US Air Force who had been searching for me since my dive buddy Pete had called the Coast Guard. He told them of the wind speed and surface current and that he was sure I was on the surface because he had heard the blasts from the DiveAlert. I have had a DiveAlert attached to my BC since first hearing one in the Dive shop in 1991. Anybody that dives with me uses one too. It moves diving safety forward by making the diver “audibly visible” even when conditions prevent you from actually seeing them. The DiveAlert is one piece of gear NO-ONE should get into the water without." - George L.
