Comparison Garmin Instinct 2 vs Garmin Instinct

The main way to connect a wearable gadget with external devices. For smartwatches and fitness bands (see "Type"), this refers to a connection to a smartphone or tablet, while in the case of watch-phones, it usually refers to headsets.

— Bluetooth. Wireless technology for direct communication of various devices with each other. This is the most popular interface in smartwatches and bracelets: Bluetooth modules can be made very tiny, the communication range even in the earliest versions reaches 10 m, and different generations of Bluetooth are mutually compatible in terms of basic functionality. Specifically, the versions nowadays are as follows:

• v2.0. The earliest standard used in modern wearable gadgets. The possibilities of such a connection are more modest than those of more advanced versions, but they are often quite enough.
• v3.0. A standard that combines classic Bluetooth v 2.0 and a high-speed “add-on” for transferring large amounts of data.
• v4.0. Further, after 3.0, improvement of Bluetooth: in addition to the classic and high-speed format, this version added Bluetooth Low Energy technology. Support of this technology is especially useful in fitness trackers, which usually transmit small amounts of data, but constantly.
• v4.1. Modification of the 4.0 standard described above with improved protection against interference while working with LTE mobile communication...s.
• v4.2. Another improvement of the 4.0 standard, which introduced, in particular, improved data protection and increased connection speed.
• v5.0. The fifth generation of Bluetooth, released in 2016. One of the most interesting improvements is the introduction of two special modes of operation for Bluetooth Low Energy: extended range (by reducing speed) and increased speed (by reducing range).

— USB. Wired connection to a computer/laptop using a USB cable. A rather specific option, found in some fitness trackers and children's beacons. During working hours, such a gadget functions completely independently, and the USB connection is used only occasionally, for some special tasks: transferring collected data to a computer, charging the battery, changing some settings, etc. This is not as convenient as a permanent connection via Bluetooth, therefore, in wearable gadgets, USB is rarely used as the main connection method.

— 3.5 mm (mini-Jack). Another wired connection method, almost completely similar to the USB described above and differing only in the type of connector. Also, the 3.5 mm plug is designed mainly to work with smartphones and tablets, and not with computers. However, it is also extremely rare.

Types of notifications, as well as basic voice communication features supported by the gadget.

— Call notifications. Notifications about calls coming to the smartphone connected to the gadget, and for watch-phones — about calls to the watch itself. In classic smartwatches and fitness trackers (see "Type"), the specific functionality of such notifications can be different — from the usual sound or vibration signal to the ability to see the caller's number on the screen and accept/reject the call. But anyway, such notifications are often more noticeable to the user than the own signal of a smartphone deep in a pocket or bag.

— SMS notifications. Notifications about SMS messages received either on a smartphone connected to the gadget, or on the gadget itself, if it is capable of receiving messages (all watch phones and many children's beacons have this capability, see "Type"). The specific features of notifications can be different — from the icon "you have received a message" to the ability to read SMS and reply to it. Anyway, this feature often provides additional convenience — at least it reduces the likelihood of missing an important notification, and often also eliminates the need to once again take the phone out of your pocket / bag.

— Voice control. The ability to control the device through voice commands. In order for a smartw...atch or fitness tracker to perform some simple feature, it is enough to say its name aloud.

— Voice assistant. In watches with voice assistant support, the level of user interaction with the device is displayed in a new qualitative way. The most popular virtual assistants are Google Assistant and Amazon Alexa. In Apple devices, the role of an assistant is performed by Apple Siri, in Samsung wearable gadgets — a virtual assistant Bixby. Unlike the voice control function, the assistant does not just turn on this or that feature, but allows you to perform certain operations in applications that require feedback.

— Sound signal. The ability to give sound signals using the built-in speaker. This feature will be useful primarily in situations where the gadget is not on hand — for example, if it is used as an alarm clock and is removed at night.

— Vibration. Vibration signal similar to that used in mobile phones. In wearable gadgets, such a signal is especially convenient due to the fact that the device is constantly in contact with the wearer's skin, so that the vibration is perfectly felt — and regardless of the level of noise around. In addition, vibration mode is also useful in quiet environments where a loud sound signal is undesirable.

— Built-in microphone. Own microphone built into the body of the device. Such equipment can be used for different purposes, depending on the type and features of the gadget. First of all, voice communication is impossible without a microphone. Another feature for which a microphone is required is the voice assistant (see above). And in children's smartwatches, it may be possible to remotely turn on the microphone from the parent gadget and listen to what is happening around the child; see the relevant paragraph below for details.

— Speakerphone(speaker). The ability to work the gadget in hands-free mode, using the built-in speaker and microphone for conversation. In a conventional smartwatch (see "Type"), this feature allows you to talk through the watch without removing the smartphone from your pocket; in watch-phones, speakerphone allows you to do so without headphones and headsets, and for children's smartwatches, this feature is almost mandatory. However the volume of the built-in speaker is usually low, so in a noisy environment its power may not be enough.

Screen size in dots (pixels) horizontally and vertically. In general, this is one of the indicators that determine the image quality: the higher the resolution, the clearer and smoother the picture on the screen (with the same size), the less noticeable are the individual dots. On the other hand, an increase in the number of pixels affects the cost of displays, their power consumption and requirements for a hardware platform (more powerful hardware is required, which itself will cost more). In addition, the specifics of using smartwatches is such that there is simply no need to install high-resolution screens in them. Therefore, modern wrist accessories use displays with a relatively low resolution: for example, 320x320 with a size of about 1.6" is considered quite sufficient even for premium watches.

The density of dots on the screen of the gadget, namely, the number of pixels that are on each inch of the panel vertically or horizontally.

The higher the PPI, the higher the detail of the screen, the clearer and smoother the image is. On the other hand, this indicator affects the price accordingly. Therefore, the higher the density of points, the more advanced, usually, this gadget is in terms of general capabilities. However, when choosing a screen, manufacturers take into account the general purpose and functionality of the device; so that even a small number of PPIs usually does not interfere with comfortable use.

The amount of own storage provided in the design of the watch/bracelet. This memory is used for permanent storage of various information: call log, received SMS and other messages, additional applications, data on physical activity for a certain time, etc. The larger its volume, the more data can be stored in the device without the need to clean it to free up space. On the other hand, in the operation of smartwatches, large volumes ( 64 GB, 32 GB, 16 GB, even 8 GB and 4 GB) are not always required, capacious drives are quite expensive, and replaceable cards installed in corresponding slot (see below).

The time that the gadget can work on one battery charge (or the supplied battery) in normal use.

Normal mode, as a rule, means working with a relatively low load. At this time, the display can display some data, and basic functions can also work (counting steps, periodically checking heart rate, etc.), but in any case, power consumption is low. Therefore, the operating time in normal mode can be quite impressive, up to several weeks, or even months. However, when choosing, it doesn’t hurt to also pay attention to the stated time in active mode (see below) — especially if a long operating time is critical, or you plan to use the gadget intensively. The actual autonomy of the device will most likely be somewhere in between these two values, depending on the actual load. If only the time in normal mode is indicated for the gadget, you should choose with a certain reserve.

The time that the gadget is able to work on one charge of the battery in the active mode of use.

For watch-phones (see “Type”), this usually means a talk mode, for other gadgets, an intensive work mode when numerous features and sensors are used and there is a constant exchange of data with a smartphone/tablet. However, the specific understanding of the "active mode" for different manufacturers may vary: some indicate the time at maximum performance (that is, in fact, guaranteed battery life), others — in some kind of "average mode". However, anyway, this is a fairly clear parameter that describes the battery life of a particular model quite well (and is much closer to real indicators than the time in normal mode mentioned above).

Note that for models with a GPS sensor (see "Navigation"), the specifications may additionally specify the time of active operation using such a sensor. See "Operating time (GPS)" for details.

The time that the gadget is able to work on one charge of the battery (or supplied battery) when using a GPS sensor.

This parameter is specified mainly for high-end tourist watches designed for experienced travelers, military, rescuers, divers, pilots, etc. Such devices use advanced GPS receivers, which themselves can consume quite a significant amount of energy; in addition, the operation of the receiver is inevitably accompanied by the use of other features — transferring navigation data to another device (usually via Bluetooth), working with its own built-in maps, etc. Therefore, the battery life while using GPS turns out to be rather modest — it can be significantly less time in active and even less in normal mode (for both, see above).

We also remind that the battery life mentioned in specs is approximate — in fact it may differ (in one direction or another, depending on the use scenario). Nevertheless, it is quite possible to evaluate the actual capabilities of the watch and compare them with each other: the difference in the claimed battery life usually proportionally corresponds to the difference in practical battery life.

Body colours in which the gadget is available. Note that in this case "stainless steel" is only the name of the shade, the body material itself may be different (for example, aluminium).
