I had an incident where I went overboard the other day while wearing my hydrostatic auto inflatable PFD. I won't mention the brand, but it was a high dollar one from a big name retailer. As soon as I went over, I was able to calmly grab the gunnel of my boat and work my way to the back of the boat so I could re-board. I was thinking the whole time that this PFD is going to go off any minute and scare the [censored] out of me ( I have heard them deploy in person, and they can startle you even if you're expecting it). So long story short, it never did inflate. The PFD is only a few months old.
I am wondering if anybody else has had a similar issue with a hydrostatic type PFD that inflates based off of water pressure.
P.S. After reading online, it looks like the unit needs to be submerged in at least 4" of water to discharge. Maybe I never got it 4" below the water surface. Oh well, I may be going back to a traditional PFD after this.
Thanks

Why not mention the name brand? I would like to know if this is the type I have or not.

Good point squib. I guess there is no harm in mentioning it. Again, maybe the circumstances that I had were not critical enough for the unit to deploy. My unit is a Mustang Survival Elite Inflatable Life Vest with HIT.

This is why I only use a full mustang pfd. Just not worth it to risk that 1 time it doesn't inflate when you really need it to

Looks like you found the info you are looking for, but the hydrostatic mechanism has to reach its pressure point in order to inflate, it is not going to inflate from getting wet on the surface.

I had one inflate while I was driving the boat. Probably the closest I have ever been to a heart attack. I thought I had been shot. Never used it again.

Here is the answer from Mustang.
Auto Hydrostatic Inflator Technology will automatically inflate under water pressure, not inadvertently in rain, spray or humidity

Fishing a tournament with my brother early one morning and he must have stepped on the pull cord while his was laying in the bottom of the boat. Scared the [censored] out of both of us when it went off, it sounded like a gun shot! This is what he looked like for the remainder of the day..... Hahaha!!! I wear a full Mustang pfd because I'm just not confident in the inflatable vest...

Here is the correspondence I received today from Mustang just in case anybody that owns one was curious: "These units are manufactured to go off when you absolutely need them to go off. It takes the inflator itself to be submerged in 4” or more for 5 or more seconds. There are some factors to take into account also so I have included information from the manufacturer of those Hammar inflators that can better explain how they are manufactured to perform. I have also attached some non-inflation questions that will help our QA department in their investigation into the non inflation complaint if you choose to send back after reviewing the information below. Please review the below information and also fill out the non-inflation questions attached to the best of your knowledge. From here we will then take the next step in getting you taken care of the best that we can. Here is some useful information regarding the performance of the Hammar Auto Hydrostatic Inflation Technology (HIT.) Below is the link to the inflator manufacture’s website that explains how the Hammar inflator works. The website does a good job explaining the mechanics of the inflator. There are also a couple of videos showing examples of users falling into the water. http://www.cmhammar.com/products/personal-safety-mob/lifejacket-inflator/in-water-performance/ Below is a direct link to a video by Hammar showing one possible circumstance in which the inflators will not activate. https://vimeo.com/203200474 Whether the inflator will or will not activate is complicated. It really depends on a number of factors such as: · The orientation of the user’s body when they impact the water · The depth under water the user goes to · How long the user is under water · Lastly if the product had been rearmed was the air fully removed from the bladder All these factors can influence when or if the product will inflate automatically. That being said, assuming there is minimal air inside the bladder, the product will activate if the Hammar inflator is under 4 inches of water for more than a 5 seconds. However as shown in the above video when the user falls in backwards and is floating in a neutral position the Hammar will not activate. One of the benefits of these inflators is they will only activate when you need them. If a user is face down or under the water for longer than 5 seconds the product will inflate. Please let me know if you feel like the PFD should have still inflated after going through the information above and we will take the next step. Thanks so much for your time and have a wonderful day."
