SCUBAPRO has learned that certain Galileo dive computers have experienced screen freezes. It is therefore voluntarily recalling 1,486 dive computers sold in the United States from May 2015.

The affected products are UWATEC Galileo Luna and Sol dive computers that have the following serial numbers:

Galileo LUNA:   from 150422 0058 001 to 150903 0338 005

If your UWATEC Galileo Luna or Sol dive computer does not have a serial number in the ranges listed above, then it does not fall within the scope of this recall.

Consumers with affected computers should return them to an authorized SCUBAPRO dealer or to SCUBAPRO directly. You can download a Return Form here. Consumers will receive free replacement units in early 2016.

Within the last 48 hours an exciting announcement has been made which has the potential to revolutionise Scubapro's computer line. Johnson Outdoors - whose brands include Scubapro and Sub Gear - has announced that they have acquired SEABEAR.

SEABEAR specialises in the development of underwater instrumentation. This European company was founded and is headed up by Dr Arne Sieber. Sieber is a research scientist with knowledge of applied sensor technologies. His work has been published in peer reviewed journals, he has filed 9 patents and spoken at many international diving conferences such as EUROTEK.

Now Arne Sieber is joining Johnson Outdoors' 'Diving Unit' which makes and markets Scubapro dive equipment. A spokesman for Johnson Outdoors stated that "SEABEAR’s technology expertise will strengthen innovation and enhance opportunities."

Arne Sieber stated that he shares Johnson Outdoors’ dedication to create advanced, reliable products that make diving safer and more enjoyable. "We are thrilled to join the Johnson Outdoors’ family, the SCUBAPRO brand and to be part of an exciting future,” Sieber confirmed.

Scubapro Launches 'Human Factor' Mantis Computer

We are entering the age of the 'Quantified Self'.

This was recently confirmed when Fitbit - the company that manufacturers a suite of devices that track your steps, calories burnt and active minutes - floated on the New York Stock Exchange in June 2015. The Financial Times reported that within minutes of Fitbit making their public debut, their shares soared 52 per cent.

Divers tend to be more self-aware and engaged with their personal fitness and physiology, probably because of the nature of the sport. Being able to self-track your body is a natural step. We are curious and hungry for data.

With the launch of Scubapro's Mantis M1 it looks as though some of the thirst for this knowledge will be quenched. Scubapro state they have launched "a dive computer like no other. The first and only wristwatch-style dive computer to incorporate Human Factor Diving™ (a combination of Human Factors, Ergonomics, Biometrics and Wearable Technology) into its design, enabling you to live your life in dive mode, and create detailed 'real-time' self-tracking reports on how your body is functioning, both above and underwater."

For once, let's consider the après diving activities first. This feature-rich timepiece has an alarm clock, and a stopwatch. Scubapro has also incorporated an altimeter that can track your hiking adventures. In the event that you decide to climb a mountain not long after diving, the computer is smart enough to alert you both visually and audibly 'that today this walk in the black forest is probably not one of your wiser decisions' - you are going to altitude too quickly. It also has a chronograph with lap memory for running, or you can switch it into Swim Mode to record your swimming time, number of swim strokes and swimming distance.

Scubapro has been quick to realise divers are ageing (and so are their eyes) and they have utilised the CHROMIS font on the Mantis M1, thus ensuring that the LCD segmented display has extra-sharp large alphanumeric characters that are quite readable underwater. The marine grade 316 brushed stainless steel casing has no holes in it. Instead the four rounded buttons are magnetic. They activate the relevant electrical reed switches inside, thus the casing is kept watertight. What does this practically mean for the diver? Because the unit is sealed, you are able to get your CR2032 battery (rated for 300 dives / 2 years) changed by a professional watch shop in a remote location, rather than returning the unit to Scubapro because the technician only has to worry about one compartment seal.

I get the feeling that Scubapro has designed the Mantis M1 to be a robust working tool for Divemasters and Instructors. By the very nature of our job, we can be quite tough on our equipment. For instance, the mineral glass face is deep set on the Mantis M1 to minimise the chance of scratching the face. (I was most upset when I scratched the face of my Citizen Promaster on a stage cylinder in March 2000). And strap security has also been considered. In the event that one pin fails, you won't lose your computer. It will remain on your wrist because it is secured by two pins. Small details but important ones.

Scubapro state the UWATEC ZHL-8 predictive multi-gas algorithm "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." So lets discuss this.

Scubapro revealed at the 2014 DEMA Show they intend to incorporate a 'Skin Temperature Monitor' towards the end of this year (2015) so that this factor can also be integrated into the Mantis M1 algorithm. On the face of it, this sounds really quite exciting. In reality it probably means more questions than answers for the diver.

During your basic training you should have been taught when planning a dive in cold water, to plan the dive assuming the depth is a number of metres or feet deeper than actual. This concept conservatively pads the table, adding in a safety factor because temperature can affect a diver's ability to on and off-gas nitrogen. You are not going to off-gas optimally when you are cold.

Scubapro marketing materials confirm they have included thermal management in their algorithm since the early 2000. There are a few wrinkles with this. The computer may be able to measure water temperature but it has no idea how you, the diver, is clad and what your personal temperature is. Are you gibbering in a semi-dry or nice and snug in a decent set of thermal underwear and a fully working 'dry' drysuit? By incorporating a Skin Temperature Monitor, Scubapro intend to measure, in real time, the skin temperature via a chest strap (that also measures your heart rate), and include this data in their decompression algorithm.

The monitoring of one point will not give you an accurate measurement, what is needed is the status of many points. However, as far as I am aware, this is the first dive computer to actively consider trying to incorporate real time diver temperature into their algorithm, therefore Scubapro should be given a pat on the back for this important development. Whilst the whole body status may not be wholly accurate, this is a necessary step to get us moving to where we want to be, ie full physiological monitoring and interpretation.

The Mantis can operate in four underwater modes - Apnea, CCR, Deco and Gauge. Three of these modes (Apnea, Deco and Gauge) have been pretty much standard on many computers for several years. With rebreathers becoming more popular it is good to see that manufacturers are now considering including a CCR option and the Mantis has a fixed PPO2 (partial pressure of oxygen) for closed circuit rebreather diving. The Mantis can also handle three gas mixtures, from 21% nitrox through to 100% oxygen, giving you the flexibility to carry additional staged gas in addition to your primary breathing gas.

Shearwater Research Release Firmware Updates For Their Dive Computers

Shearwater Research, Petrel Dive Computer, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, Gradient Factors, mixed gas diving computer

Vancouver based Shearwater Research has announced they have released firmware updates for their dive computers.

Shearwater Petrel and Petrel 2

The Petrel Firmware V28 includes several changes for all Petrel Users. It also includes support for the new hardware features for the Petrel 2.

Predator

The Firmware V59 is recommended for all Predator users, because it addresses a flaw in the dive logging that can prevent dive logs from closing properly. This affected several of the previous versions, therefore it is recommend that all users update accordingly.
