Now… I sure hope you remembered yesterday was Valentine’s Day or else you might be out in the cold with your significant other. Just saying….. But if you’re out in the cold, just remember, today is a new day. Yesterday I attended a beautiful wedding. It truly was gorgeous and on the day of love, what more could you ask for? I even made cookies for it. It’s kind of become my new thing… decorating sugar cookies. I was watching a video the other day that was showing a lot of techniques that I already knew, and one was called the spider’s web. It was pretty cool, even if you don’t like spiders… no one says you have to put a spider in the web, it could be used many many other ways.
Okay, okay, I’ll quit with the sugar cookie talk this early in the day, although maybe it’s late in the day if you’re reading this late in the day… just saying… and I say that a lot… just saying. Haha. Anyway… So you didn’t come here for my twisted sense of humor or to learn about my new hobby, what you did come here to see was the latest piece of equipment we’re going to discuss. Now, the question is, can I tie any of the upper in with this piece of equipment and I just want to share that, yes, yes I can. How you ask? Well today’s piece of equipment is the Mantis M2. Mantis… you know there is a spider called a Praying Mantis, right? Oh, gotcha! Your welcome. Now on to learning about the Mantis M2. (and yes I shake my head in disbelief every time I manage to do that….)
Mantis M2 with Transmitter (or without, say you already have one…)
The M2 Dive Computer is an Air Integrated dive computer. Now what’s the difference between air integrated dive computers and dive computers that are not air integrated? With an air integrated dive computer, the computer can calculate your remaining bottom time (RBT) based off of current air consumption rate. That is a handy thing to know because it gives you extended bottom times as it recalculates based off of air consumption rates and depth. So as we learned in the diver interviews, Dive Like Mike if you have to, there’s no shame in that!
When SCUBAPRO developed this dive computer, they created the Human Factor Diving™ component. Okay, okay, so what is that? The Human Factor Diving™ is an exclusive SCUBAPRO approach to equipment design that combines Human Factors and Ergonomics, Bio-metrics, and Wearable Technology. Laymen’s terms please. Okay, so basically it was designed for the interaction between products and the people who wear them, the science of measuring and analyzing a human’s make up, and making gear to be worn on the body. Through the combination of these things, a person gets “real-time” tracking reports on you body both at surface level and while diving at any depth. How cool is that?
This wrist style dive computer is marketed as the go-anywhere, do anything, “intelligent” personal dive computer.
This personal dive computer was created with you in mind. It uses “intelligent” abilities to monitor your personal data during workloads to maximize your operational efficiency while alerting you to over-stimulation to help avoid potential problems before they escalate into major issues.
This stylish dive computer that mounts to your wrist like a watch is loaded with surface features as well as dive features. This includes hoseless air integration, electronic navigation, plus the Human Factor Diving™ features.
The casing, or outside, is made of the highest marine-grade 316L stainless steel. The attractively machined bezel ring features engraved button labels and decorative hash marks. Wait a minute… what is a bezel ring? Good question!! A Bezel setting is a type of elevated collar that wraps the faceplate completely in metal edging.
Then there is a black inner face ring on the display which enables the mode indicators to stand out for easy reading adding a pleasing contrast to the LCD screen. On the outside of the watch are four metal control buttons allowing for easy navigation through menu’s. Each button is assembled in a module using triple O-rings to allow for leak-proof reliability.
The “fun” in this watch is I mentioned it sits like a watch… well it’s the size of a large watch so you can wear it all day every day. For your 8-5 job, it keeps time like a day watch, but it is great for after-work activities and exercise as well. The altimeter and thermometer allow you to monitor upper elevations while hiking as well as a chronograph with lap memory which is great for the runner. Better yet, wear it in the pool to record swimming times, number of strokes, and even distance. It is also a reminder on your arm that you are in fact a diver… so at any minute, you’re ready to dive in to that lake or ocean and take a scenic tour.
The M2 also comes with a HRM (heart rate monitor) allowing you to monitor your heart rate at any depth—another SCUBAPRO exclusive feature. This belt also monitors your skin temperature and factors that into your decompression algorithm for safer, more efficient dives.
This personal dive computer comes with 4 underwater modes: SCUBA, Gauge, Freediving, and CCR. It also has Multi-Gas algorithm to accommodate three gas mixtures, plus a fixed algorithm for closed circuit rebreather diving. And after your dives, there is LogTRAK software for both PC and Mac users included plus an app for Android phones.
Okay, Technical Information (left to the pros!!)

All dive computer algorithms factor in depth, bottom time and gas mix to calculate deco time. However, SCUBAPRO’s ZHL-8 ADT MB PMG is the only dive computer algorithm that includes a diver’s breathing rate, heart rate and skin temperature as an indicator of workload during a dive and adjusts the decompression plan to avoid risk factors.
These enable the adaptive algorithm to adjust for each diver’s experience level, age and physical conditioning. Choosing a microbubble level between L0-L5 allows you either take up less nitrogen or off-gas more quickly.
Heart Rate Monitor
By visually monitoring your heart rate you can better assess your workload — real time — and promptly react to heightened stress or over-exertion. At the same time, the dive computer incorporates this information into its workload calculation, adjusting the algorithm to make the dive safer. On a less critical level, measuring your heart rate also lets you focus on increasing your endurance training, which allows you to transform your love of diving into a fitness sport.
Skin Temperature Monitor
This patent-pending feature provides yet another aspect of your physiology that can be factored into the workload algorithm. Extreme cold can affect a diver’s ability to off-gas nitrogen. This additional information lets your algorithm update its decompression calculations to improve the diving experience.
Profile Dependent Intermediate Stops (PDIS)
Calculates an intermediate stop based on how much nitrogen the body has absorbed, taking into account the current dive, previous dives and breathing mixes
Can be a valuable aid when exercising or lap swimming in shallow water. By keeping track of strokes you can also calculate distance.
Can be calculated by combining heart rate and workload data. In today’s fit-conscious society you’d be hard-pressed to find anyone not interested in how many calories were burned over the course of the day’s dive. (The Calorie Tracker is available when using LogTRAK software.)
Whew… now that’s a lot of information.
Last summer I was actually offered the opportunity to dive with our SCUBAPRO Rep’s Mantis M2 Dive Computer. I was one of 2 people that day during the Safari Hunt that was allowed to dive with this computer while Scott was in town. Let’s just say, it took one dive to get used to the operational functions of this dive computer versus what I was used to, and then I was sold. Now I’m off to eat Sugar Cookies that may or may not have a “spider” web on them .
