Rating of the best computers for diving, freediving and spearfishing for 2022

A computer for diving and spearfishing is a necessary thing, without it it is very difficult to keep track of the basic necessary indicators. The quality and reliability of such a device ensures a safe and comfortable stay of a person under water. In the article, we will consider the main recommendations and tips for choosing such a device, what new products are on the market and how to choose the right option for the price.

Description

A computer for diving, freediving and spearfishing (decompression meter) is a small underwater mechanism (most often in the form of a watch) that ensures safety while being underwater by transmitting the necessary indicators to the screen of the device.

Main characteristics:

• depth temperature when diving;
• the amount of nitrogen in the body;
• a signal about the excess of any important indicators;
• keeping a log of dives.

Criterias of choice

Consider what to look for in order to avoid mistakes when choosing

1. Depth. An important indicator, many models are not designed for diving more than 100 meters Consider your sport and depth when buying.
2. Circulation scheme. At great depths, a closed type of circulation will be required, they are especially relevant for spearfishing.
3. Where could I buy. Such equipment is not cheap, it is important to remember this. Especially when you want to order online from an online store. Be sure to check the completeness and performance of the mechanism when buying. Appearance may differ significantly from the photo on the site.
4. Which company is better. The best manufacturers of such devices guarantee the quality and reliability of the device. It is better to overpay a little for the company's brand and end up with a device that does its job well. The life of a person under water depends on it, a failure in the operation of the device can lead to irreparable consequences.
5. Maintainability. You can replace the battery on most models yourself without contacting a service center, this is very convenient. Specify at the time of purchase the possibility of self-replacement.
6. The level of training of the athlete.If you are a beginner and just discovering the underwater world, you should buy a not very expensive model with limited functionality. Most of the features for advanced users will not be used at the initial level.
7. Screen backlight. The brightness of the backlight and the size of the numbers on the screen is also of great importance. On lakes where the water is muddy, it will be difficult to see small numbers and dim backlighting. Consider this criterion when choosing a device.
8. The amount of built-in memory. Convenient when the device has a large amount of memory. Otherwise, you may lose your first dives, with no way to recover them.
9. Communication with PC. To transfer data to a PC, this function must be supported on the device. In the kit, usually, there are adapters for connection. Some models allow you to save profiles remotely, without a direct connection to a computer.
10. Dive planner. Not all models have this feature. This feature allows you to simulate a stepped profile dive in detail.
11. Additional functions. It is very convenient when such a device can be worn in everyday life, there are models that, in addition to the main functions, have additional ones, for example, they show the time.

Types by type of use of the respiratory mixture:

• Air. The air model does not take into account oxygen toxicity.
• Nitrox. For mixtures with high oxygen content.
• Trimix. Designed for the use of mixtures: nitrox and trimix, in addition to oxygen and nitrogen, they include helium.

Types by type of cylinder pressure monitoring:

• Without monitoring. Budget models that determine the main functions (depth, number of dives, time).
• With monitoring (air-integrated).All information about the pressure in the cylinder is displayed on the monitor, which is very convenient.

Types by the number of respiratory mixtures:

• one mixture;
• several mixtures, such models allow you to connect up to 10 types of mixtures.

Types by type of respiratory cycle:

• open respiratory cycle, with such a system, the composition of the respiratory mixture does not change from the rate of breathing, only from depth;
• semi-closed system with active supply, the composition of the mixture varies with the depth and rate of breathing;
• closed systems with electronic control, the supply of the mixture is automatic, does not depend on the depth and rate of breathing.
