What does Fenix 8 / Tactix 8 Need To Have To Make You Upgrade?

Quantified scientist (a basic YouTuber) i have watched and he has done tests with the very first firmware of these watches and then never does it again. Please share other clinical studies you’ve done or found with the sleep tracking also. 

Resting HR on the morning report would be great. I check mine every morning. 

Oh!  That’s disappointing. 

Im not biased but every wearable is going to show something different than the other. I doubt that a HR sensor on a watch will ever match a brain wave machine in any regard

I don't like most of the ideas on here.

Eliminate the touch screen.  It's pointless on a device with buttons and this isn't a smartwatch.  Eliminate the solar charging unless Garmin has aggregated enough data from its customers to determine that it does offer a compelling increase in battery life. Otherwise, it's an unnecessary cost.

More sensors.  I like someone's idea of a depth sensor for diving.  ECG is pointless unless it has FDA approval. Skin temp and perspiration sensors to monitor hydration and whatnot.

Anytime there are innovations to the Firstbeat Analytics features I perk up.

Use weather data more.  Factor humidity and wind. Offer a way to set up planning for ideal sport times (if temp is between 65 & 85 f, humidity < 60%, wind < 12mph, and sunny, it's an ideal running time.  If wind < 10mph I can fly my drone, or > some other mph it's good sailing weather... stuff like that.  Anything that encourages going outside.

Get rid of the ebike "exercise" activities... Seriously?

That's about all I can think of.  The idea of supporting more colors is interesting- though not an AMOLED display.

Cheaper watchbands and a trade-in program.  I've spent sooo much money in this ecosystem on an expensive scale, expensive bp cuff, footpod, and 3 chest straps (because they keep falling apart).  It's my decision but it'd be nice to get some sort of perk for being loyal.  Esp. with Coros, Suunto and the various smartwatches creeping up in feature parity.

I love the daily training suggestions. It is a nice upgrade over my previous Fenix 5.

Dumb ideas are anything that chew up battery life.  Eg. sim/mobile features. Buy an iWatch or whatever. This is meant for environments that don't have cell coverage.

AMOLED & touch screens.  Buy an iWatch.

Fenix 8 Must have features:

• Same battery life with more features.
• Led Display with better resolution. (Exist in other models)

Sensors

• ECG (exists in other models): Checking manually 
• Blood Pressure: Checking manually 
• Blood Glucose Tracking: manually or check every [hour/min]
• Body Temperature: manually or check every [hour/min]

Application

• Native Smart Alarm: wake up in the best sleep stage
• Add watch faces with new application versions like in Apple watches [great idea like in Nike watch face change color depends on your total km]
• Nike Run
• Apple Music

Better integration with IOS health application

Wireless charging!

I would buy immediately if there is a bigger screen in smaller housing. Solar would be nice with a glass that is less reflective. With the new maps, larger storage needs to be added. 

I would definitely not buy if there is Amoled screen and LTE connectivity. 

Garmin should take a closer look at Suunto Vertical. While Vertical isn't a true competitor to Fenix, there are a few innovations that make Vertical a very strong alternative to Fenix for some categories of users, such as adventure and ultra endurance athletes, trail runners, mount-bikers, climbers, etc. 

1) Much stronger battery life when using multi-band GPS, which means that multi-band can be used by default without having to do unreliable tricks like SatIQ. A couple of times I tried using SatIQ it glitched resulting in inaccurate position and pace, presumably when switching from one mode to another. Suunto Vertical can go for 60 hours in multi-band GPS mode, which is longer than any competitor. 

2) Adaptive backlight. Sapphire versions of Garmin Fenix have been long criticized for having poor contrast, which makes it harder to read the display in some conditions, for example in a deep forest. So far Garmin has done nothing to address that. Vertical has an ambient light sensor that adapts the backlight to the conditions - simple and elegant.

3) Map readability. Garmin maps are detailed but in my opinion they are difficult to read when moving fast. Garmin maps work fine for hiking or backpacking where it isn't a big deal to stop and take some time to look at the map. Suunto Vertical maps are optimized for glancing at the map when moving fast and when conditions may be sub-optimal. Furthermore, Vertical has a truly high contrast map where all elements are bold and have very high contrast. If you need to ensure that you are on the right path, that is all that needed.

4) Truly sensitive and accurate compass. In my opinion Garmin compass implementation truly sucks for faster paced activities because it has enormous lag. Often it takes a few seconds for the compass to orient the map, which makes reading the map confusing during fast paced activities such as trail running. Also, sometimes when I run fast through a sharp turn, I notice how both the map position and the orientation can still show me behind the turn while in reality I have already passed the turn 5-10 seconds ago and am already 30-50 meters (100-150 feet) past the turn. In contrast, Suunto's map orientation is instant and precise, and smooth. 

5) True turn notifications for GPX courses. Suunto generates turn notification based on the map analysis in the app. Garmin's implementation generates "fake" turn notifications which are based on the course shape and not the actual map data. That works in some cases but fails horribly in some other cases, for example when running on trails with a lot of switchbacks. Not only Garmin's implementation inserts a lot of unnecessary turn notification where there are sharp bends in the course, it also misses some true turns if they are not at a sharp enough angle.

All of these features make me very interested in Suunto Vertical despite it not having a lot of other fancy Fenix features.

Things I want the most:

- Much longer battery life. Thickness/ size of the watch can be increased (imo it makes the watch look tougher).

- Higher contrast MIP (black looks deeper). 
- Much harder DLC bezel, which is more prone to scratches/ nicks. 
- Improve the accuracy of GPS only/ all system gps. 
- Harder ohr sensor glass (ceramic glass like in Apple Watch)

- Bring back the removable pins like in previous fenix models. 
- Increase in screen size by removing the ring between solar ring and bezel. 
- Ability to track naps. 
- Google maps integration.

- A bugs-free software.
