There are several systems named Galileo (Galileo) – this is satellite navigation, and the ticket reservation system, the same name is carried by the NASA probe. In the same article we will talk about a modern computer for divers carrying this name.


Many people consider the very appearance of such a device on the market a revolution in scuba diving. Today it is the only device in the world that meets European standards for working at a depth of 330 meters.

Since the announcement Galileo has become rife and rumors. Often, people did not even see the device even in the eye, however, based on the announcements, brewing activities on the designation of shortcomings are bred. Consider the main misconceptions about the underwater computer Galileo.

Galileo supports only three nitrox mixtures, so for true techno drivers it is useless.

There is a stereotype in the society that asserts a diver computer in the form of a device with a previously approved set of functions. The situation with Galileo is quite different. In underwater devices, finally, a real computer approach has appeared – appropriate mathematics and programs appear to the existing hardware. Concerning the same myth, you can talk about the limitations of a particular firmware version of the computer. Indeed, the basic equipment of the device does support only three mixtures, but nothing prevents you from downloading a new firmware that will support a larger number of mixtures, including gel ones. It should be noted that for most techno drivers it is enough and basic firmware – because it has, for example, the meter mode, other features of Galileo, which are not in devices of this class.

Galileo is a raw product, so you should use it not earlier than a year or two after entering the market.

This myth is an echo of the past, when manufacturers recalled their computers when they found errors in them. Users were offered to either stop using them or expect a replacement for a new model. With Galileo this does not happen. Firstly, the basic firmware itself has already been worked out on SmartTec and AladinTec 2G computers, and secondly, it is possible to fix errors in this computer by the user himself, who just needs to download the fix package from the manufacturer’s website.

The device is quite expensive, its functionality is not worth it.

Everything in the world is relative, if you compare the price of Galileo with devices of this class, you find that the price is even lower in places than in analogues. And how many of the competitors can boast of an infrared port and a digital compass? It is worth taking into account the fact that the equipment will sooner or later become obsolete, and the user will want to purchase a newer model, this approach is applicable to cars, computers, household appliances. But the manufacturer, the firm Uwatec foreseen such an opportunity! Nothing prevents to increase the capacity of Galileo by constantly updating the firmware. New software allows you to successfully integrate all the new products, including hardware (new sensors, devices). It should also be noted that these devices are assembled in Switzerland, undergoing an increased control over the performance of all operations both individually and in a complex. The highest reliability, admittedly, has its price. Specialists Uwatec developed the technology of filling the body with oil, resulting in the work of Galileo at depths of up to 330 meters. These features are unique for devices of this class. Equipment from other manufacturers has a much higher percentage of failure, so the choice of divers is obvious. It is for Galileo that wisdom is justified: “we are not so rich people to buy cheap things,” corresponding entirely to the whole philosophy of diving. The real price for the Galileo base set, which includes the cardiac sensor, transmitter and case is less than 1500 dollars, which is not expensive for a device of this class and performance.

The cardiac sensor can not work in breadcrumbs.

To debunk this myth, the manufacturer simply performed the Galileo testing in the basin. It was proved that the sensor works correctly both in a wet suit and in a cracker. So this myth has no practical ground.

The computer does not support deep stops.

“Deep stops” – just a fashionable term. In themselves they do not even fall under the action of any of the decompression algorithms. It has recently been established that if deep stops are applied during ascent, this will reduce the amount of microbubbles in the diver’s blood. As a result of these experiments, a simple rule was worked out – it is recommended to make intermediate stops for about 1-2 minutes approximately half way on the ascent, this is to increase the safety of the ascent. In the apparatus of most manufacturers, this option is not paid attention. The user himself decides whether to include or not such a mode and what will be its duration – 1 or 2 minutes. In the case of Galileo, the manufacturer approached this issue very responsibly. Uwatec conducted its own research, finding out the algorithm for suppressing microbubbles, these results were included in the decompression algorithm for the device. The user is offered to choose one of five security levels, and the computer, in accordance with the real dive profile itself, provides recommendations for performing safety stops. Their depth and duration depend entirely on the diving profile of the diver. It is curious that safety stops in this case are not mandatory for suppression of microbubbles, in contrast to decompression stops. In the event that the diver stops the computer, the computer automatically reduces the level of security, making appropriate changes in the overall decompression calculation. It can really be assumed that Galileo does not support the rule of deep stops, in fact the computer uses its own algorithm to prevent the appearance of microbubbles.

The computer uses a rare type of battery, so replacing it is very problematic.

Galileo uses a lithium battery CR2NP or CR12600SE, and in transmitters – CR2450. Such devices are manufactured by different manufacturers and are not at all rare, as they are used in various widely used devices, including cameras. The desire to find such a battery on street trays will be naive, but it is easy to find in specialized stores. Uwatec dealers also supply a special kit, which includes an additional battery with o-rings.

Programs for Galileo are expensive.

This statement can not be attributed to all software for the computer. The fact is that all programs for Galileo can be divided into two groups. One of them includes completely free samples (localized firmware, fixes, etc.). But paid products include specialized firmware, for example, a program for trimix mixes. Such products will always be paid until real prices are indicated, but Uwatec promises to make its offer real and affordable. You have to understand that most divers do not need these firmware, but those people who really need them understand the price of their security and will be ready to pay for it.

Galileo – a pure marketing and advertising trick, there is no acting model in nature.

By this myth, competitors are trying to put off the revolution that Galileo will inevitably produce in the world of underwater computers. Do not consider this product a fantasy, this is already a reality. Serial release of the computer has already begun, the computer can be ordered, and there is a possibility to do this in Russia. Naturally, the output of such a revolutionary product is inevitably accompanied by an agiotage, and the increased demand causes a certain deficit.But we must take into account that Galileo is going to Switzerland, the volume of output does not correspond to the volume of consumer goods. So, willy-nilly, wishing to buy Galileo will have to wait. You should not succumb to live queues or offers to make a deposit from unknown persons; you should take into account that the list of authorized dealers is available and published on the Russian Galileo Team website, it is better to trust reliable suppliers and their conditions. And all the news of the Galileo market are covered on the website.

Galileo is very complicated in management.

The mobile phone also has many functions, but their abundance does not cause shock for most users, a similar picture will be with Galileo. The computer has a user-friendly interface, is equipped with detailed instructions that will help to master this tool even for an inexperienced user unfamiliar with this kind of technique. Yes, and official dealers plan to conduct special workshops on how to work with both the computer and its software.

Galileo is not recommended for beginners.

Often beginning divers try to save on the most necessary. However, if you do not take into account the economy, you can easily prove the use of the device is a beginner. Firstly, the device is equipped with a Russian interface, alarms are also given in a language that is understandable to us, which will eliminate the misinterpretation of signals in critical situations at depth. Secondly, Galileo strictly monitors the behavior of the diver under water. The computer has 11 acceptable levels of ascent rate, while other manufacturers are limited to a maximum of three. Thirdly, the cardiac sensor allows you to take into account the status of the diver by monitoring pre-stress conditions, enabling you to conduct training with breath control. Fourthly, Galileo will allow using his own microprogram to avoid the situation when the air suddenly ended. The considered algorithm for suppressing microbubbles leads to the fact that with the help of the computer the beginner immediately learns to the correct immersion profiles. Do not forget that Galileo is also a compass-navigator, a logbook, a scheduler and a manometer – all these functions make the computer an indispensable dive guide. An important function is the ability of Galileo to control the air volume in the balloon of the partner, which gives great opportunities for family diving. The user can change the batteries while fully saving the information, since such operations use non-volatile memory. The display configuration can be adjusted to suit your needs by choosing the size of letters, information output fields, and the possibilities for entering personal data. Finally, the creators promise that even after a year or two of active use by the computer, the diver will be able to outgrow his capabilities, therefore, regardless of the experiments, Galileo will successfully serve the right service.
