Epson ProSense 307 GPS Watch Review

Overview of the Epson ProSense 307 GPS Watch:

The Epson ProSense 307 GPS Watch is a part of Epson’s new ProSense line of GPS watches. This multi-sport GPS watch with built-in optical heart-rate has rather a lot to like for the typical runner and/or multi-sport athlete. Nevertheless, we additionally see some key shortcomings which I will clarify under. The 307 checks in to the middle of the line of 5 ProSense watches. The excellent news about this model is that it consists of all the features and performance of the 2 costlier ProSense watches (the 347 and 367) so we will assume the accuracy and software/usability would be the similar. What’s good versus what could possibly be improved? Learn on to seek out out!

Word: given the number of options out there on GPS watches today I’m going to concentrate on the gadgets I hope most people care probably the most about. In case you are new to considering a GPS watch or just need a full listing of all of the options obtainable on this watch you’ll be able to see that by way of the Amazon affiliate link (and you may be supporting URP should you determine to purchase this manner too!)

Key Specs & Notes:

  • Weight: 51g / 1.8oz (center of the street on weight; a touch heavier than most Garmin’s however lighter than most Suunto’s)
  • Battery life: as much as 20 hours in GPS+HR; 24 hours in GPS-only (all 1s recording specs)

Now for more particulars. On this assessment, we’ll break things down in to 4 areas:

  1. What’s good: the brand new, differentiating, or just nicely designed or constructed features or points of the product.
  2. What might be improved: tweaks or enhancements that could possibly be made to make the product better.
  3. When to use it: the conditions or situations where the product excels.
  4. The way it compares: my present go-to product(s) and how this compares.
  5. Do you have to purchase? My general suggestion on whether or not to purchase or not.
  6. Buying Info: the place to go to buy this product.

I’ll attempt to be as succinct as potential. In any case, you’ve in all probability received extra operating you can do at this time!

What’s good?

  • The function set at this worth point. Garmin nor Suunto supply a $250 (or less) watch with this many options. With Garmin or Suunto you both should pay extra, and sometimes a lot more, to get the same battery life; or, it’s a must to sacrifice options like a built-in optical HR sensor. Epson did an amazing job at combining the absolute ‘must-haves’ for my part at a pretty worth level.
  • The battery life. This, together with a watches accuracy, are the 2 largest issues that GPS watch manufacturers need to get right. And thankfully, Epson did with this watch. 20 hours in GPS+HR mode or 24 hours in GPS-only mode (both 1s GPS recording) is great and really appreciated at this worth point.
  • I saw what I might contemplate to be common accuracy with every activity I did. Each when it comes to GPS accuracy and optical HR accuracy. (Editor’s notice: I do not pit one GPS watch vs. another on the identical run to match accuracy after the very fact. I simply depend on what I consider to be accurate from the routes I commonly run along with information of my very own perceived exertion / fitness ranges and the HR numbers I’m seeing.)
  • The display. Epson markets it as an EasyView show and I like that straightforward time period. It is straightforward to view in any respect angles and in vibrant sunlight. The show itself is a contact smaller than I would really like however due to its superior readability it’s not a deal-breaker.

The show is straightforward to learn from all angles

  • Knowledge area customization. As much as three strains of knowledge, across 4 screens (plus a lap display) might be custom-made for every sport mode. Also, you possibly can add graphs (e.g., HR graphs) instead of knowledge fields. Very cool!
  • Superior metrics. Metrics like VO2Max and lactate threshold are driven (i.e., licensed) by a company referred to as FirstBeat. Garmin uses this firm as nicely for his or her superior operating metrics so it’s great to see Epson doing this as properly.
  • HR works underwater. This is the first optical HR sensor I have used that works within the pool. Whereas rehabbing from a current damage I used to be spending every other day ‘running’ in the local pool and I used this watch to examine in my effort levels. I used to be impressed with its means to trace my HR and provide me with real-time in addition to submit exercise HR knowledge to research.
  • Utilizing the app, you possibly can shortly tap anyplace on the planet and save that as a waypoint. You then push those waypoints directly to the watch. Solely Epson permits this as we speak so if Waypoints are your factor then this is fairly neat-o!

What might be improved?

I’m going to particularly cover points I have seen during runs or in establishing or adjusting the watch. This isn’t designed to be the end-all-be-all of bugs which will exist within the product.

  • Usability of cellular and desktop apps. Whereas it’s nice you need to use either the cellular or desktop app to make all the required settings changes to the watch there’s some critical usability considerations in terms of the cellular app. Almost after display change or setting adjustment takes some time, typically a very lengthy whereas. Not solely that but the desktop app feels fairly outdated.

Get snug, you may be here some time.

  • Lack of on-watch setting changes. You can’t modify the info fields/screens on the watch itself; you must use the cellular or desktop app to do that. Suunto customers might not mind this limitation but Garmin users positive will. Similarly, you can’t create an interval-based exercise on the watch and as an alternative have to first create it on the cellular or desktop apps before pushing it to the watch.
  • Lack of sensor help. This is an odd omission I need to say. Because of the lack of any ANT+ or Bluetooth Sensible connection choices you can’t use it with any external sensors (i.e., no energy meters, no HR chest straps, no third-party optical HR sensors, and so on.). This makes little or no sense to me when you think about that they have a cycling sport mode yet don’t permit cadence or power meter help.
  • As already said you can’t create intervals on the watch itself. Not only that however even if you create the interval workout on the cellular or desktop apps you can’t embrace a warm-up or cool-down as a part of that general exercise. So, very similar to Suunto has completed up to now, you might want to start a run to finish your warm-up. Then, you need to cease and save the run. Then, you need to begin a exercise to complete the interval portion, and then stop and save that exercise. Then, you need to begin one other run to finish your cool-down earlier than stopping and saving it. Argh – I really feel like I’m taking crazy tablets! Garmin has figured this out so long ago – why is that this so arduous? Do GPS watch manufacturers not understand that athletes routinely do interval-based training each week and want to merely start the watch originally and cease it on the end whereas having the watch beep or vibrate what every step must be?!

After far too many clicks I finally found out tips on how to edit the interval settings solely to be disillusioned that you simply can’t embrace a warm-up or cool-down phase.

  • Type issue. The ProSense 307 isn’t terrible in serving double-duty as an on a regular basis watch however it’s also not the sexiest GPS watch out there. I’d like to see the depth decreased (i.e., the watch face slimmed down a contact), the display measurement elevated slightly, and the watch band widened.

It’s not the thinnest or sexiest GPS watch I’ve ever seen (Epson ProSense 307 on the left, Garmin 230 on the appropriate)

When to make use of it?

  • Any run as much as 20-24 hours the place on-watch adjustments or fairly quick cellular/desktop app adjustments usually are not needed (i.e., you’re a set it up once and run type of individual).
  • The Epson ProSense 307 additionally serves double-duty as a nice swimming watch too
  • Due primarily to the shortage of sensor help it might not be my first selection as a biking or triathlon watch

Comparable products to match with:

I’ll solely examine it with competing watches I’ve truly used:

  • Suunto Spartan Sport Wrist HR (evaluate right here): Suunto easily wins on usability and their apps however the Epson wins on almost all hardware-related features (e.g., battery life, accuracy) so in consequence I’m decide the Epson ProSense 307 over this Suunto variant. It additionally helps the Epson is half the worth!
  • Suunto Spartan Sport Wrist HR Baro (evaluation coming quickly): Battery life and accuracy have been improved in the Baro compared to the Sport Wrist HR variant. Nevertheless, at $550 I’m unsure it’s greater than 2x the watch of the Epson ProSense 307. What this really comes right down to is how much do you worth the barometric altimeter and the way typically are you utilizing the cellular and/or desktop apps?
  • Garmin Forerunner 230. My trusty day-to-day watch. The Garmin 230 lacks a built-in optical heart fee sensor and it lasts 16 hours in comparison with 24 for the Epson ProSense 307 in GPS solely mode. Nevertheless, it’s far simpler and quicker to adjust and easily simpler to use. Plus, the worth is identical. Once more, hardware versus software trade-offs. Until I really need to monitor my coronary heart fee I’m probably sticking with the Garmin 230 as my most heavily-used watch in the intervening time.

Do you have to buy?

So, the $250 question – do you have to buy the Epson ProSense 307 GPS Watch?

In a word, perhaps. In case you are the sort of runner who units up the info fields you need to see as soon as and simply need an correct, long-lasting GPS + HR watch – this can be a great worth. Nevertheless, if you wish to commonly modify knowledge fields, have a watch information you through interval-based workouts, or use the look ahead to cycling or triathlons as properly then I consider better choices exist right now.
