Disappointing. Surface horn is great, but the UW horn is a waste of money. My buddy rarely hears it and he actively listens for it. No-one else has a clue.
The performance has has always been average and I have persisted for a year and a half.. no longer!
Sorry guys, great idea but still needs work.

This is a perfect item, with the H2O feature, you can get your buddies attention easy, many reviews say it isn't loud enough, you must be freakin deaf...ease up on the IPOD sessions. I have never had any of my buddies unable to hear it. The air feature is great, we do a lot of spearfishing and it is perfect to signal the boat for a pick up when sharks are around, so you can keep your gun pointed below!

The entire reason I purchased this unit is because of it's use.I was impressed with the decibel level of the air horn portion of this device. This unit works well on the surface but under water uses vast amount of air to function.

I'm glad I bought it. I use it all the time when I dive and it has become an integral part of my BCD. It is great underwater to call your buddy and on the surface the sound carries a long way.

Like many others, I religiously research a product before dropping $$ on it, especially one pertaining to diving. When this unit came out a couple years back, I was interested but hesitated to buy it based on some poor reviews I had seen online. Eventually though, I decided to give it a shot and thus far have been impressed. The H2O signal is definitely loud enough and hasn't yet failed to get my dive buddy's attention. I find that it helps to acclimate the other diver to the noise immediately upon entering the water as the sound isn't as distinct as some (say metal clanging on metal) and could get confused for ambient noise on heavy surf conditions. The surface signal is deafening and will be an invaluable asset in an emergency situation.

I wish I had this thing when I accidentally forgot my SMB on a dive and surfaced far from the boat!!

Can't give it 5 flags until I try it in action for real life - and it saves me - but above water no doubt you WILL be heard. Piercing loud noise. The WARNING says do not blow this above water without protecting your ears - without doubt ALL of you will at least try it once (as did I, I was curious). I blew it in my apartment haha and yes, protect your ears because it IS very loud! Happy to know that. In real life, they suggest you submerge your head underwater and blow the horn above the water surface. Warn your buddy/buddies!!

The 'buzzer' below water is average. As in other posts, you must be nearby your target to attract attention. I prefer using my underwater metal shaker/ringer so I won't waste air but the underwater buzzing function, though not as functional, is a nice 'extra' feature.

If it saves your/my life, it's worth it. Buy one for peace of mind.

This unit works well on the surface but under water is little or no use & uses vast amount of air to function

I own one of these but this particular model was purchased as a Christmas present for one of my dive buddies. The unit is well made, works well above and below the water. My only issue is when you attach this to your Air2 you have to use your hand to help hold the regulator in your mouth unless you turn your head a few degrees. I simply purchased another inflator hose and mounted it on that hose. The knob to select surface or subsurface is easy to use. The horn is extremely loud and could damage your ears if not careful. The underwater quacker is loud enough and gets peoples attention. It makes others feel safe to know they have a way to signal if the need arises....

Excelent. It´s very easy tu use. Less hevier than install the old system.

I was impressed with the decibel level of the air horn portion of this device. The underwater portion is very disappointing as it produces almost no sound. My buddies could not hear it through their hoods even when they were within a few feet of me underwater. I wish I'd purchased just the basic version w/out the underwater feature.

I had the Original Dive Alert and was very pleased with it. When I changed to a ScubaPro Air2 Inflater Regulator I has to get a new signal because the Air2 needs a Hi-Flow connector. I decided to "upgrade" to the Dive Alert Plus.

1. The construction is pretty flimsy and I am afraid it will eventually break apart with routine handling.

2. I have a harder time using this device than the original "Surface Only" Dive Alert as the ergonomics are poor. The device is fairly bulky and can also interfere with the use of the power inflater and alternate air source.

3. The real show stopper is how weak the underwater sound is. The underwater horn is really just a bubble-maker. A tank pinger makes a louder sound. If you want a well built air-powered underwater noise maker try an Aquatec Scub Alert Under Water Signaling Device (a quacker).

I plan to return this piece of junk and get an original Dive Alert.

Comments about Aqua Dive Alert Plus:

I must agree with the other two reviewers. On the surface it's fine. Underwater its just a waste of back gas. I have verified my own experience with two other divers who were dumb enough to buy them. Given its single functionality (surface) it's too big and too expensive. Mine's going in the trash.

Comments about Aqua Dive Alert Plus:

We replaced a faulty Dive alert with this one so it could be heard above and below the water. It is not as audible on the surface as the original, and barely audible under water. I am greatly disappointed and would not spend the money on this product.

Comments about Aqua Dive Alert Plus:

Would have to agree with the other review of this product. I bought this for dive instructing and have to say I am extremely disappointed with it, the surface signaling device works great, but underwater is just a stream of bubbles. Dont think anyone heard it - even me!

Comments about Aqua Dive Alert Plus:

The above water horn work superbly, but the entire reason I purchased this unit is because of it's use below water and it is very sorry underwater. I used it in 5,15,and 20 feet of fresh and brackish water and it didn't do anything but blow bubbles. Very unhappy with this product!
