Journey of 540 Dives



This post goes out to the dedicated and hard working men of ALERT's Unit 51. 

I have been on the road for most of April in the great state of Texas, teaching at the International ALERT Academy.

This is one of the twice-a-year moments that I get to teach there, and it is hands down my favorite group to teach.

We cover a LOT in a very short amount of time! In just 14 days, these young men are taken from not being very confident in the water to open water, advanced open water, and then through the special response diving course. Like I said, a LOT!

There are a few reasons why I enjoy this.
  1. These guys are beast. Like Nike, they just do it. No reservations or holding back when they are told to do something- they just get it done.
  2. Big, giant, human shaped sponges. All of them are eager to learn and grow. 
  3. Competent. It's not like they just learned to dive in the ocean and now they won't dive for another year. No.. in just these two weeks they put 20 dives under their weight belts. Most people learning to dive won't even do that many dives in a year!
  4. Let's not leave out comical. It's not perfection all the time, and there are a lot of screw ups, but we have fun doing it! The difference is that these guys are willing to learn from their mistakes.
These are only a few of the many reasons I enjoy working with ALERT men. I'm also an Alumni of the Academy, so there's that...

There is one thing that stands out the most, however, among these young men. It's their desire to go out and do. They have a fire lit inside to take the skills that they learn and go and serve their communities and public safety departments. And that's exactly what we need. We need the next generation of public safety divers to get excited to take on the job that is there.

An interesting shift is going on in the public safety diving world right now. It's the shift from the experienced old salts to the young bucks. Those that have been in the world of Underwater Search & Recovery and have been successful in their craft are either moving up their respective ladders, or they are retiring. The massive amounts of knowledge and wisdom that comes only from experience also leaves with them. This is leaving a learning gap in many departments. The old is out and the new is lost and left to find help and training on their own; which often means poor training.

But it's this fresh batch, the newbies, the rookies, the ones with that drive to get it done, that make my job a joy to do. I look forward to the future of these ALERT men and the impact they will have on their communities. Keep up the good work guys!

The positives of negative buoyancy!

Finally, some clear thinking on the importance buoyancy has in the diving community. Wait a minute, what diving community is it important to? As a matter of fact, how many diving communities are there? Why don’t you just think about those two questions while I continue with the first thought.

Buoyancy is all about Archimedes, who was a Greek mathematician/scientist living in the 3rd century BC.
Using scientific methods he determined that “…an object immersed in a liquid partially or totally is buoyed up by a force equal to the weight of the liquid displaced”.

Well, have you thought long enough on those two diving community questions? The answer is… understanding and mastering  Buoyancy is important in every diving community.
In the recreational diving community the attainment of Neutral buoyancy at any depth is the desired objective to be considered a competent diver. However Positive buoyancy is the most sought after and taught skill for a dive profile to have a happy conclusion. Then there is Negative buoyancy which has become the bain of sport divers and those who teach them.

In the Commercial diving community the knowledge, skills and abilities  (attitudes) when it comes to buoyancy is more a job for job tool and capability. That means that Positive, neutral and negative buoyancy is mission dictated and performed professionally to a successful conclusion.
In the Special Response Diving community Negative buoyancy is king! This community includes Police divers, Public Safety divers, emergency response divers, tactical divers, military divers, forensic divers and any other group that performs underwater search and recovery missions. Believe it or not trying to find something on the bottom while neutrally buoyant is a fools errand. Now some will argue that neutral buoyancy keeps the diver from disturbing the bottom, and that may work once in a while, but if you want to find something on the bottom you must become the bottom. This is achieved only with negative buoyancy. The only way to constantly have a positive resolution to an underwater search is becoming proficient in the use of negative buoyancy.

Remember, in underwater search & recovery you get positive results when negative buoyancy is king!

The rise of technology, and the fall of common sense.

We got the call at about 9:30 AM. We loaded up, headed out, and arrived at a small lake that was nestled in the middle of a highway interchange. We were informed by Florida Highway Patrol that the incident had happened the night before, when a person driving a pickup truck, had lost control and driven off the interstate and gone into this lake. The driver had gotten out and was fine, but the truck was now making friends with the fishes.

I geared up and walked to the waters edge as my partner got the search line. We could see the tire tracks where the vehicle had gone in, and so using that as our LSP (Last Seen Point) we started an arc search. About 10 minutes later I located the vehicle that was, in fact, a pickup truck. It was just sitting there on all four wheels glistening in the early morning sun, about 120 feet from shore.

Well, to make this story short so I can talk on what this post is really about; we recovered the truck and all was good. But when I had come up after locating the truck, the wrecker operator was just laughing and shaking his head. He told us about a recovery he was at a few days before, where 6 off duty police officers had spent 6 hours using side scan sonar, looking for a 20 foot box truck in a 50 foot wide canal that was only 20 feet deep. He just laughed and said, "It took them 6 hours with all those guys and technology, and you two come out here, and in 10 minutes, find a pickup in a 40 foot lake with a piece of string!"


Does the title make sense now? You see where I'm going with this? Dive teams get sold on all kinds of new gadgets and gear, and pay for it by trading in there knowledge of the basic principles of Public Safety Diving. A sad side note: the amount of money these teams try to get to buy said gadgets, is money that could be used for upgrading basic equipment, or be used to pay for additional training days.
Give me money to pay a team some overtime to train with the basics, and I'll give you better results then any piece of technology can produce. You think that's a bold statement? Let's take a look at a recent event in New Orleans.




I have a few things I would like to point out. First, is the amount of people who had been involved in the search. Multiple departments and volunteers assisted in looking for this missing teacher. The State Rep. in the video says that the area had been searched before but the vehicle had been missed. Now whether that was with side scan sonar or with search patterns I don't know.
Second, is the relative closeness to shore where they located the missing teachers vehicle.
Third, there were a lot of other vehicle recovered! This tells me that they do not go into these areas regularly.

As I researched this story, I kept asking one question. Why was that car missed? If divers had been in there and they were proficient at their search patterns, why was that car not located?

We have to be careful that we are not sold into the thinking that big expensive toys make it all easier, or even more effective. You can only have one of two answers. I located the object, or the object was not in the search area. Are your search methods ingrained into your team so well that you can confidently give one of those two answers? Or do you have doubt when you get done with a search?

I'm not some stone age diver that thinks that technology will take over the world. I think that there some applications where side scan sonar is very useful. Heck, I was interviewed on the Nancy Grace Show one time about the use of side scan sonar in an investigation. In that investigation it was very helpful in locating the missing person. Things like side scan sonar and metal detectors can definitely be useful tools to assist your team, but I believe that you need to know and be able to perform effectively, the basic search patterns first!

So what I'm really trying to say is: Don't sell your common sense to buy technology. That's my point. Ok, I'm done.

Search negatively my friends!

Jordan and the missing dead.

I had been a Special Response Diver for only 4 weeks. I was about to move into my 3rd phase of training at the International Alert Academy. I had chosen to go into Aquatic Operations as my specialty and it was the Friday before we were to start. We had just finished our end-of-ERT training ceremony and promotions and were ready to kick it back for the weekend, when the training officer over Aquatics, came up to those of us that would be going into his unit and said, "Pack your bags boys, we leave in the morning. We're getting deployed to help with a body search that's part of a murder investigation."

After myself and the other guys had a mild heart attack from excitement, we tried to act cool and put on faces that said whatever, it's just another day in the office. But who were we kidding?! This was the ultimate call out! We would be putting all that training to the test!

All through our training in Miami, we had found cars that were either stolen or insurance fraud. But this was huge! We were heading to Lubbock, Texas to assist the local Sheriff there. The whole trip out there, we thought about what our Instructor had taught us about searching for a drowned person or murder victim. "You never find a body. Bodies find you." Cool as cucumbers. Ok, maybe cucumbers in a microwave.


We showed up to a very warm welcome from the requesting agency, who was just happy to have body's there for this work. As we pulled up to the marina that was the staging area, we noticed a few other divers that would be coming out with us. We were told that these were Public Safety Divers who had been diving for many years. Great. Our first public performance, and now we have to deal with the pressure of impressing these veterans with all the stuff we think we know.

Our team of greenhorns quickly learned a valuable lesson. Don't be intimidated because of titles. Let me explain what gave us this revelation.
First let me explain these two men that were gearing up with us. One guy was 6'2" and probably weighed about 350 pounds. You may think I'm exaggerating, but I'm not. While putting on his wetsuit, through his grunts and groans, and winded banter, was telling us about how his wetsuit was custom made because he was so big. It cost him over $600 for this thing, and was a wonderfully bright yellow and red with purple accents. He was so proud! He needed almost 40 pounds on his weight belt!
His partner was next to him putting on the most complicated looking harness I've ever seen. One of my teammates asked him why he had so many knives and shears. He proudly answered that they never get in the water without a minimum of 5 cutting tools. You know...in case you drop the first 4 trying to cut your way out of the giant fishing line factory you plan on swimming into down there.
So as these two gentlemen were putting on their rescue helmets (again, not joking) we boarded the boat and set off to search.

The lake we were searching was not really deep in the search areas. Sometimes it was only 2-4 feet deep, but it still had to be searched. Where this lake lacked in depth, it made up for in vegetative growth. A lot of saw grass and decomposing saw grass root balls were along the bottom in our search areas.
You may be asking yourself right now why this is important. To most experienced Public Safety Divers it's not really important; however to a straight up newbie it is. You see, the visibility was about 8 inches, and every time my hand touched one of these decomposing root balls my thought process would go something
like this...

*Hand touches slimy root ball and inhales regulator down esophagus*
"Ahhh I found a body!"
*Realizes it's just a root ball*
"Woohoo! It's not a dead body!"
*While pulling out regulator from esophagus comes to realization*
"Crap. Now I have to keep searching."

And repeat.

So for two days this went on. We did not locate the victim, but we did recover a shotgun that was used in a different homicide. To say the least we learned a lot! Our first call out taught us some things that only the real world of public safety diving could teach us.

1st - We learned that just because they have a bunch of cool toys and expensive wetsuits, does not mean they are good divers. Their methods and equipment prevented them from searching effectively and efficiently. Don't feel like you have to impress anyone. Just do your job and let others decide by your actions if you're good enough.

2nd - Just because you did not locate a body or a gun does not mean you failed. Remember, there are only two answers... I located the object, or, the object was not in the search area. It takes a team to cover the area we covered in those two days. And as a team we accomplished our mission.

3rd - You can still breathe out of your regulator even if it's down your esophagus! I would not have believed it unless I had experienced it so many times. I wonder if there is a specialty card for that...

There are 2 kinds of divers in the world... -Post by Michael Gast

As a full time police diver for over twenty five years I have had the blessing and the curse of observing in-service training and its effect on the dive resource capability of various agencies. The purpose of in-service training is to hone the knowledge, skills and abilities (attitudes) of the diving resource so as to maintain a level playing field among the various diving personnel. The other side of the coin is simply training for the sake of training. This being said, what is the circumstance when your team meets for in-service training?  Since most of you reading this are in some way involved in underwater search & recovery or rescue I will leave you to decide the type of training the team in this story practiced. 
One evening my partner and I were dispatched to a possible drowning in the south end of the county. Upon arrival the fire rescue divers were just exiting the water after searching for over forty-five minutes. Their on-scene commander had determined it was no longer a rescue, but is now a recovery for the police divers.
Since the first order of business was to gather information and determine the last scene point (also referred as a datum), and never having worked this rock pit before, I asked two of the eight divers about the depth and bottom condition. They both stated that the depth was over 60 feet with zero visibility.

With the sun setting and having talked to the one witness who claims to have watched the victim go under, my partner and I swam out to the last seen point with an anchor, down line, float and a search line. Because of the reported depth the down line was over sixty feet long, although when the anchor hit bottom I still had over forty feet of line in my hands.


After securing the excess line to the float we descended to twenty feet and landed next to a Ford van sitting on its wheels. Being over two hundred feet from shore in twenty feet of water on its wheels this van was an enigma to be solved later. Being able to see the whole van in this twilight the visibility was established as fifteen feet horizontal. Using the van as our base I tended my partner as he conducted an arc search starting out ten feet and arcing 180 degrees on each pass with ten feet increments each time. On the second pass my partner signaled that he had located the victim and secured the line around the victim’s chest.
The search that we conducted lasted less than five minutes.

What did we do differently than the eight divers who searched for over forty five minutes?
When I told the last fire diver on the scene that there was a Ford van in the middle of the lake, his response was,  “ I know, we put it there for training. This is one of our training lakes”.
Well it is your turn to determine the type of in-service that goes on here!

REMEMBER!
“HOW YOU TRAIN, IS HOW YOU PERFORM WHEN IT GETS REAL ”

What it is...

This is probably not the only conversation out there like this. It's most certainly not a new conversation. It's just a vocal exclamation of what really goes on. From training to equipment; team structure and SOP's (standard operating procedures); to what's the best search method--- this blog is all about getting the conversation heard.

Now before I continue, we have to set some ground rules. First, we need to define what a Police Diver is and what a Police Diver is not. Let's define what a Police Diver is not, upfront.

A Police Diver is NOT a Professional Diver. Now before you get your diving ego hurt, let me explain. A Professional Diver is someone who makes a living from diving. They could be a boat hull cleaner, a sport diving instructor, an underwater welder, or a safety diver for movie production. These are people who dive to bring home the bacon. Police Divers are not Professional Divers, they are Police Officers. Their job is to enforce the law. One of the tools they use to do so is diving, just the same as their defensive driver training or dynamic entry training. It's a skill to increase their effectiveness.

Now to define what a Police Diver is, we need to get one thing clear. Sport or recreational diving requires you to use your eyes, while Police Diving requires you to be able to perform your mission entirely blind. This is where Police Divers stand apart from the rest. They have to complete the mission in odd hours of the night, sometimes in water that would never be found on the cover of National Geographic, and in more cases than not, do it without the use of their eyesight. This criteria also applies to Fire Rescue Divers and divers in other emergency response organizations. They are often called Public Safety Divers.
(In a later post we will go over the differences and similarities between the two).

Ok. That's out of the way.

MenFish is about informing and encouraging Police and Public Safety Divers in their already challenging job.
This blog, like I said before, is the conversation. I will be sharing a lot from my experience and lessons learned, but I want to hear from you as well! Send me your stories; comment on posts, or just read the posts and be anti-social.

So...let's get this conversation started!
