Purchase Guide: After trying out all CASIO, GARMIN, and EPSON, we found out the best solution for outdoor watches with GPS for each purpose [Part 2]

Outdoor watches with GPS are now becoming indispensable gear in sports and outdoor fields. It is not just ABC (altitude, pressure, and orientation) functions, but is continuing to evolve, allowing you to understand your current location and display maps offline.

Among these GPS outdoor watches, this project is to compare the three typical models designed for use in mountain climbing: the CASIO PRO TREK Smart WSD-F20 , the GARMIN fenix 5x Sapphire , and the EPSON Wristable GPS for Trek MZ-500 , which are actually used at the same time for mountain climbing, and to see the characteristics of each model and their strengths and weaknesses.This time, we will compare what and how much they can be used for day climbing. I hope this will be of some help to those who were just wondering whether to buy it or not.

Detailed comparison review (part 2)

6. Functionality and what you can do

Let's compare the functions of each model, or to put it simply, the types of things that can be done with this watch. The three models we compared this time share the basic functions of checking clock, direction, altitude, and atmospheric pressure, and tracking location information using GPS. However, as you enter more detailed areas, what you can do will vary greatly depending on your individuality. Of course, these devices are not just for mountain climbing, so the functions they are looking for differ depending on the purpose of the user, so the impressions of each person differ from person to person, but this time we will mainly compare and evaluate features related to mountain climbing and hiking.

GARMIN - A powerful fitness support machine for athletes

First of all, as expected, in terms of functionality, the richness and detail of the fenix 5x To be honest, it covers so many functions that I cannot write about here, so I will only touch on the important points here. As expected of a flagship model, it can be used for a variety of activities, including mountain climbing and trail running, running, running, cycling, swim, canoeing, fitness, golf, and more, and data measured by a wealth of sensors, including optical heart rate monitors, is displayed on the screen to suit each activity. What's more, the displayed content can be customized in great detail, so it's amazing that you can arrange it in your own way, even if you're ready to go. Offline maps are already built in, so you can always display the map without having to download them in advance. Sending GPX data for a mountain climbing route that you have created in advance to the clock will be useful in the field like a car navigation system (though the feeling of using it on an actual mountain climbing is not accurate enough to provide detailed navigation for each real fork, so it's still a play for the navigation system). By synchronizing your smartphone with your watch, you can also use it like a smartwatch, such as notifications, schedules, weather forecasts, incoming calls, etc. in a timely manner.

In addition to distance, time and location information, we also record temperature and heart rate changes, average pitch and calorie burnout in detail, and based on these, we also record training effects, VO2Max values ​​(whole body endurance and aerobic ability), lactic acid threshold, and predicted marathon time! The analytical features for athletes are truly impressive. These can be viewed through the dedicated management app "Garmin Connect," and provide tips on training loads, making them perfect for those who want to improve their records and perform well with each activity.

 

CASIO - It can be used casually like a smartphone even for outdoor use, and is convenient for everyday use~

the WSD-F20 cannot compete with the finer features, it is not inferior in terms of its breadth, including everyday use . First and foremost, it is very appreciated considering this price range that offline maps can be displayed in clear display (though they require downloading in advance). It can display information for a wide range of activities, not only trekking, but also cycling, fishing, paddle sports, snow sports, surfing, and golf. Especially when it comes to mountain climbing in Japan, the third-party YAMAP is extremely excellent. There were some unstable times at first, but now it's useful for some reason. On site, you can view a 25,000th topographic map of the Geospatial Information Authority of Japan, which contains information such as course time, offline (it is necessary to forward it in advance if you have an internet connection), and after a mountain hike, you can clearly record the course you walked. As an ordinary mountaineering enthusiast, this is enough functionally enough.

Furthermore, this model, a smartwatch equipped with Google's "Wear OS," can be used in a wider range of situations than Garmin, in that it can be used not only for outdoor activities but also for everyday use as it is, and can be used in a wider range of situations than Garmin. Of course, you can sync your smartphone with your watch to view and operate notifications, calendars, weather forecasts, incoming calls, etc., and depending on the app, you can also reply to messages using voice. You can also use it in your own way, such as audio search, input and displaying notes, checking news, emails, calendars, translation, and health management, depending on the app, and you can use it in your own way, without using a smartphone.

Recently, it is no longer possible to connect to home devices such as smart speakers using Google Assistant (although I haven't actually tried it yet). While there are complaints that sensors such as heart rate monitors and thermometers have been omitted, and athletes are unable to track and analyze using more detailed data, what is the big appeal of the WSD-F20 is that it currently has sufficient functionality and ease of use for beginners and general hikers, and is expected to see a wide range of apps, including those not just outdoors, in the future, with the influence of the giant Google, and that there is a hope that things can be made will expand even more. The drawback is that for better or worse, it depends on the third-party app, and if you are using maps offline, you need to download the relevant area in advance.

EPSON - Specializing in functions for mountain climbing and running

the MZ-500 focuses on specific activities such as mountain climbing and running, and pursues a variety of functions . There are several disadvantages, such as the only activities that support mountain climbing and running (trail running), no offline maps (and even if it's called map display, it's only a schematic diagram of the registered route), and the ability to link with smartphones, but when it comes to mountain climbing, there are at least some useful features that the WSD-F20 doesn't have. For example, while recording your activity, you can view more detailed data in real time, such as the altitude, distance traveled, and elapsed time of your current location, as well as the speed of rising (decreasing), slope, and calorie burnout. If you are running, you can also get pitch and stride. If you register a route created in advance on your device or if it is a route registered on the main unit in Japan, it will not only navigate the time and distance to your destination at the actual site, but also how far you will need to climb (altitude). However, just like with Garmin, this was not as accurate and convenient as it was, and considering the necessary effort, it wasn't enough to make me want to use it proactively. The result is still a supplement to the project, and it seems there is still a long way to go before it can be used in practical use. NeoRun is a dedicated software that imports tracking data and manages history after climbing, and is generally excellent, allowing you to record your heart rate by recording time, distance, calories burned, steps, altitude rise, descent altitude, route of action, and optionally compare your heart rate. It can be linked to some extent with other apps, so it would be enough to say that it's only good for mountain climbing and running.

7. Accuracy: Although there are some quirks, it has solid stability that none of which is found on smartphones

Now that it's common to know your current location on your smartphone, I think it's easy to get your current location, but things aren't that easy. Regardless of the detailed mechanism, it is said that when more precision is required, there will be subtle differences in hardware and software.

This time, it is difficult to compare the mechanism itself, so we will summarize the extent of the errors by comparing the altitude and current location at the same point at various times over the past month, and by comparing the routes tracked during the mountain climb later.

In conclusion, there was no fatal variation between the three devices. However, looking at it in more detail, there were some points that I was concerned about.

First of all, in Casio, when using YAMAP, the current location and altitude display, as well as the course tracking accuracy, was quite high, so I was able to check my location information with the most confidence of the three. However, when I look at the altitude of the original "TOOL" at the same time, it is often the case that this one is off. Of course, it may be possible to improve accuracy by setting methods, but for better or worse, it was a glimpse of how it depends on the app.

Next is Garmin. Although the altimeters have automatic altitude correction set, they often slip off, so they have to be manually corrected each time. My current location is slightly off, and when I checked the trajectory later, I often saw a slight deviation compared to the others (photo above), and as a result, the walking distance was longer than the other two models (by the way, when measuring the distance, the setting takes into account the slope). Incidentally, it seems that this trend is almost the same when I ask two friends who are fenix 5 users.

While Epson's version is rarely particularly inaccurate among the three, I get the impression that it wasn't as accurate as YAMAP.

Summary - What are the recommended types? ~

We have compared three typical GPS outdoor watches for mountaineering in a variety of ways. As I have mentioned several times in each category, models with a higher price will not be more satisfying in all respects, and it seems that the outdoor watch that is just right for you will be determined by the user's purpose and purpose (what you want in the watch).

Finally, we'll summarize some of the recommendations for each purpose that we learned through this trial. In any case, there is no doubt that it is a gear that has the charm of being unable to let go of once you use it. Choose wisely and enjoy the outdoors more.

CASIO PRO TREK Smart WSD-F20

A balanced, easy to use, convenience, versatility, durability, accuracy, all-round outdoor watch for everyone

In short, the most convenient and recommended for anyone is Casio's PRO TREK Smart WSD-F20. When it comes to sports watches, models that can measure, record and analyze more maniacally tend to be popular, but in reality, there are quite a few people who use these. If you're using an outdoor watch with these smart features for the first time, I think there are many people who just want to see maps anywhere, keep a solid basic records for mountain hiking, and then use it without any stress For such users, this model is perfect.

It is safe and durable even outdoors, but the map is the easiest to read, and it is smartphone-like and easy to operate. For mountain climbing, there are apps that cover YAMAP and a wide range of other activities. Furthermore, Google-related apps, which are convenient for everyday use, are also very promising.

However, to put it simply, for those who want to master the apps, I think the current apps will feel unsatisfied. If someone who has been skilled in sports watches to some extent, such as not being able to get a heart rate, not being able to measure pitch or stride (when running), not having a temperature sensor, poor battery life, or not having dedicated activity management software tailored to the device's performance, choose this to further pursue it, (at this time), you may be disappointed.

GARMIN fenix 5x Sapphire

The best companion for ambitious athletes who record, analyze and support everything they need to improve their performance.

On the other hand, I had some predictions, but beyond my expectations, I was surprised that the Garmin fenix 5x was so amazing that I could do such a small detail. A variety of sensors including an optical heart rate monitor and the dedicated performance management and analysis software "Garmin Connect" brings together countless functions.

What's overwhelmingly superior is its performance measurement and analysis functions for running activities . This is not possible with other models at all. If you can see your VO2Max value gradually approaching professional athletes' values ​​through training, then there is no better ally to maintain the motivation of runners aiming for higher levels.

However, to put it bluntly, these are important for athletes aiming to achieve good race results, but they may not be that necessary for fan runners who want to enjoy themselves first, or for hikers who can adequately use basic navigation and tracking features. After all, in order to fully utilize these powerful measurement functions, you need to use the tedious and complicated operations and settings to train yourself daily, and continue wearing them when you sleep. Users who purchase simply because of the convenience of offline maps and navigation are surprised by the still-developed map display function, and are unable to hold its multifunctionality, and can easily predict that they will struggle with the hassle of button operation.

What I felt this time was that the reason for the high price is not because of its ultimate comfort, but rather because it is devoted to measuring and recording the information that is desired so much that it can come from the throat. For those who are satisfied with this, they will definitely be the best companion worth the price.

EPSON Wristable GPS for Trek MZ-500

Recommended for those who want to use mountain climbing and running only, measuring, navigation and recording functions as affordable as possible, and with peace of mind for long periods of time.

Even if you cannot perform as diverse and complex analysis as Garmin, you want to achieve the necessary functions at a cheaper price. It doesn't have to be color offline maps like Casio or versatility, so it's even simpler, with navigation, measurement and recording functions for mountain hiking and races, and I don't want to worry about battery as much as possible. For those people, we recommend this MZ-500. Especially since it is a monochrome LCD, the battery life is outstanding compared to the other two . It is true that there are only two functional options: trekking mode and running mode, but by narrowing it down to these two, it is relatively easy to operate in each mode, and the information displayed is simple and easy to read.

As this model was released a while ago, it cannot be denied that the interface is cheap. However, this comparison shows that we have not yet completely thrown away the basic measurement data details and accuracy, as well as a variety of slightly clever functions such as navigation using registered maps. It also has a sense of stability as a domestic watch. This model, the cheapest of all the comparisons we have seen, can be said to be the most cost-effective model if it is limited to its use as an outdoor watch for mountain climbing (running).
