Best Underwater Cameras of 2015 Voted

Hello all fans,

In December 2014, we voted the “Best Underwater Camera of 2015.

A total of 6.742 readers have voted in this valuable contest.

The question was:

Which underwater camera/action cam was your favorite in 2015?

Of course this is a general question, we didn’t define any parameters, but what I am thinking is that the results will give us an idea, though.

Nobody would say “Hey! This one is my favorite” for any camera that has known handicaps.

I want to thank every Dive With Seaman reader who voted for this contest.

Okay, I don’t want to make you wait :))

Here is the list of Best Underwater Cameras of 2015 according to 6.742 readers just like you. [Read more…]

GoPro Hero4 Session Review

My pro skateboarder friend, Onur was skateboarding while I was writing the GoPro Hero 4 Black Edition review in October, 2015. He was recording his tricks via his cell-phone. This was not easy. Finding a place for his cell phone for a better shot, trying to locate himself in front of his cell-phone and etc.

I asked him: “Why don’t you use GoPro instead?

Okay, I am a scuba diver and use my cameras underwater, but as a review writer, I know how handy the GoPro is for skateboarders, too.

Onur told me that his cell phone is doing well enough for wide angle video shots.

But I need a smaller camera that has the GoPro quality to be able to mount it under my skateboard” he replied.

All GoPro cameras were “big” for him. [Read more…]

GoPro Hero 4 Silver Edition Review

You can take high quality photos and videos with this model of GoPro.

GoPro Hero 4 Silver Edition is good for photographers/videographers (and/or who wants to be one) who likes to see what they get.

As you know, none of the GoPro action cams come with an LCD screen.

According to me, built-in LCD touch screen is the #1 feature of GoPro Hero 4 Silver Edition.

GoPro Hero 4 SilverAs a GoPro fan, I was always complaining about an LCD screen that comes with our GoPro. Some others say that this is an action cam and it doesn’t have to have one.

What I am thinking is that the new GoPro family members offer its users more than an action cam. With ProTune, you can customize some of the important settings like the white balance, exposure value and such.

GoPro Hero 4 versions are beyond single action cams. [Read more…]

GoPro Hero 4 Black Review

Another year passed…

I remember October 2013, when we were all excited to hear that GoPro Hero 3+ has been released.

It was a high quality year in terms of photos and videos underwater.

In August 2013, GoPro announced (I also announced it here in the name of the next GoPro product: GoPro Hero 4.

There were arguments about the technical specs, features and the appearance of GoPro Hero 4.

At last, October 2014 came and we finally met the brand-new GoPro.

This year, there are three new GoPro family member:

  1. GoPro Hero 4 Black
  2. GoPro Hero 4 Silver
  3. GoPro Hero

It took sometime for me to buy these products and to test them.

But before October 2014 ends, I am able to share a detailed GoPro Hero 4 Black Review with you.

This is the word that should come to mind when talking about purchasing a scuba diving equipment.

An experienced diver, a tecnichal diver, a scuba insructor and an Open Water Diver have different needs. [Read more…]

OTS Guardian Full Face Mask Review

I have always loved the idea of breathing both from my mouth and nose underwater.

No dry throat after a dive, no jaw fatigue and no cold face! Beyond these, you can even communicate with your buddy if you use the proper equipment within your full face mask.

Sounds cool, doesn’t it?

Using a full face mask during your dives is very comfortable.

However, most full face mask owners (including me) complain about the seal.

If your full face mask doesn’t seal well, you consume more air, cannot effectively communicate with your buddy/boat and of course it is very uncomfortable to clear your mask frequently.

But there is a full face mask which seals 100% regardless of the shape of your face. There are also other key features to help a diver make safe and comfortable dives!

OTS Guardian Full Face Mask6How I Met With OTS Guardian Full Face Mask

Last week, I was in Sharm El Sheikh, Egypt.

I met Jim, a British dive lover who is diving with a full face mask.

We were in the same boat, even in the same dive group.

During Jim’s preparations for our dive, I realized that it was an OTS Guardian Full Face Mask.

I have seen it on the Internet couple of times and red the comments about this unique full face mask.

Then I decided to see Jim underwater with his OTS Guardian Full Face Mask and watch for his comfort.

He was very pleasant during his dive.

I didn’t see him clearing his mask once!

That seemed to be awesome.

Couple of minutes later in Ras Mohammed National Park, I saw an Eagle Ray swimming towards us!

I was freaking out to be able to point this beautiful ray to my buddy because she was looking somewhere else. I tried to reach her and poke, used my shaker and etc. By the way, the eagle ray ran away!

But for Jim and his buddy, this was simple. Because they were able to communicate.

They watched and admired this wonderful creature while my buddy was looking somewhere else and I was trying to get her attention.

When we were back on he boat, I asked Jim about his OTS Guardian Full Face Mask.

He said it is very comfortable and sealing is never a problem.

Guess what?

He asked me if I want to use his OTS Guardian Full Face Mask in our next dive!

I was able to test OTS Guardian Full Face Mask for me and of course for you guys.

Key Features of OTS Guardian Full Face MaskOTS Guardian Full Face Mask5

I want to talk about the useful features of OTS Guardian Full Face Mask including my personal experience with this product.

If you have any questions about these features, please don’t hesitate to ask them in the comments section right below the article.

Double Sealing

OTS Guardian Full Face Mask’s best feature!

It has two seals.

There is an extra seal right above the original skirt seal.

This makes OTS Guardian Full Face Mask fit on all type of faces.

Whether you have a slim face or bushy beard, you don’t have to think about leaking. I have tried it in every positions underwater and even in up-side-down, no leaking!

Unique Equalization System

As you know, ear equalization is a question mark for divers who have never used a full face mask before.

Simply, there is a “clip” in your mask where your nose is. This “clip” squeeze your nose to help you inhale slowly and equalize.

This clip simulates your thumb and index finger just like you are performing a valsalva maneuver.

However, in most full face masks, your nose wasn’t exactly fitting this clip. Because every person has a unique length between their chins and noses.

OTS Guardian Full Face Mask offers us a fine tunable equalization system.

There are two bases in the equalization kit. One has no holes on it and you can easily set it to “high” or “low” position. This standard base is powered by suspension.

The other base has two holes. If you need to use additional pads, you can attach them to this base. Just try one of the pads and the second base if the standard base doesn’t fit.

By this way, everyone can easily equalize.

OTS Guardian Full Face Mask4Wider View

OTS Guardian Full Face Mask is a low volume mask.

Air trapped inside your mask doesn’t pull it to the surface.

It is hydrodynamic, it doesn’t vibrate in the middle of a current/when you move forward.

Last but not least, due to the low volume, the lens of the mask is closer to your eyes, resulting a better, wider view.

Right Sided Hose

The regulator hose comes over your right shoulder.

First I thought it is not that necessary, it could have come from m left shoulder.

However, right sided regulator hose is helpful because we all get used to it !

Adjustable Strap System

Just like the majority of the full face masks, OTS Guardian Full Face Mask has a two straps (also called spider strap).

You can easily adjust the straps by using the buckles. This way, your OTS Guardian Full Face Mask fits 100%.

The spider strap will readjust itself during your descent/ascend. That is a really helpful issue.

What is good with OTS Guardian Full Face Mask’s buckles is their stability. They made of hard plastic, so it looks like it takes a long period to wear.

In addition, because buckles are made of hard plastic rather than metal, they never rust! Rusting buckles are nightmares because they last very soon.

When your buckles get old enough, you can change it easily.

Surface Ambient Air BreathingOTS Guardian Full Face Mask3

This feature is what I like most with OTS Guardian Full Face Mask.

On the surface, you can save your gas by using Surface Ambient Air Breathing System (functions like a snorkel).

When opened, you breath the air outside your mask when you are on the surface then you close the valve and start to descend, switch back to the tank breathing.

When the Surface Ambient Air Breathing System is opened, there is only a one-way gas exchange. The valve takes the air in the mask, but you exhale through your second stage. This helps to get rid of Co2 in your mask.

Even if you forget to close your Surface Ambient Air Breathing System, the valve closes itself due to the increasing pressure. However, it gets a little bit of harder to breath. This is how you realize that you have forgotten to close your system and do it easily.

Surface Ambient Air Breathing System is a little wheel outside your mask (near your right eye). It is very easy to reach it!

OTS Guardian Full Face Mask Second Stage

The second stage is designed for full face mask.

You can breath easily, without force.

Mounting it to the OTS Guardian Full Face Mask is easy and demounting is even easier by the help of a single button.

There is a notch system to help you align your second stage on your OTS Guardian Full Face Mask. Then you lock it!

There are two exhaust ports on the left of the second stage. Not being at the bottom of the second stage, you see no bubbles during your dives.

Purge button is large enough and I didn’t find it hard to purge the second stage.

OTS Guardian Full Face MaskStoring Your OTS Guardian Full Face Mask

OTS Guardian Full Face Mask is a good looking mask, however it has an even better looking bag to store it.

It comes free with the purchase.

This bag looks like a regulator bag but it is thicker.

It gives your OTS Guardian Full Face Mask the best drying position.

You can either use the handle or shoulder strap to carry your full face mask.

Color Options

Yes ! Color is life!

Just like every one of us, equipment should also be colorful.

There are 7 color choices in

I personally loved the blue-black version.

What Does Seaman Say?OTS Guardian Full Face Mask2

First of all, this is one of the unique products that I suggest to everyone.

You’ll not suffer any jaw fatigue and/or dry throat.

This mask doesn’t fog due to the air system.

Adjustable equalizing kit helps every diver to equalize without effort.

Color options are beautiful.

Because there is always positive pressure in the mask, flooding is not an option. But if it happens somehow, you can easily clear your mask with a single purge button.

Ambient Breathing Valve is a great add-on to save air.

The only con for OTS Guardian Full Face Mask is the price.

It seems to be a little bit of expensive, but the cost benefit ratio does the math!

I advice all the divers to purchase OTS Guardian Full Face Mask, but don’t forget to take a full face mask course before starting to use this great mask.
