Fed Up with Instinct 2 GPS - Should I Upgrade to Instinct 3 Tactical?
You can contact garmin it wouldnt hurt. Perhaps they will give you a small discount on a i3 upgrade? Worth a shot. I had the i3 tactical for a very short amount of time and gps was great. Locked quick and it had all the accuracy that I needed. I didnt do any dc rainmaker comparison, but for me I had

Instinct 3 45mm Solar
I3 itself as model has only one “serious” problem about first firmware update from factory 5.21 to current version. 5.21 has bug with estimated battery life in days. Its problem in only estimation and you need to update using pc and garmin express program. You easily can find tutorials here. Everyth

What Garmin Watch for Surfr App
Instinct 3 solar, it has an amazing battery life between charges. Runs Surfr activity well. No touchscreen, just 5 buttons, which makes it very usable with wet hands and wetsuit gloves. Surfr will sometimes record and show a big jump on the watch, then when it uploads it to the app it deletes it. So

2X Solar Tactical vs I3 Solar Tactical
For my eyes, the better screen clarity/contrast on the Instinct 3 line was worth the extra price. If you don’t have diseased, old man eyes like me, the 2X is a better value. I’m sure Garmin will support the Instinct 3 line with more new features longer than the 2X as well. But the 2X will keep getti

Venu 4 vs Trex pro 3
Not a good competitors, each has totally different purpose. I would not go with Venu, since it is more like a women/city watch. Trex is rugged g-shock like outdoor model. I have both Garmin Instinct 3 Solar 50mm and T-Rex Ultra 2. In general, T-Rex is like a heavy tank, with lovely display, smooth O

Really wanted the Instinct 3 Tactical…
I have the I3 Solar 45mm and absolutely love it. Did a software update out of the box and a couple of weeks in not an issue in sight! Very happy with my purchase except maybe an old set of eyes struggling with the smaller text but that’s my fault not Garmin’s! I had an OG I1. It’s a big upgrade and

Does instinct 3 45mm solar have Sleep Coach?
Hi, question is pretty much in the title. I've bought this watch and it's so cool and nice, but Sleep Coach nowhere to be found, tho it is advertized instinct 3 should have it. FM v.9.21. What can be possibly wrong?...

Is the Instinct 3 really worth paying twice as much as the Instinct 2?
I have the 2X Solar. For me, it's one great watch. What you have to look is the age of the watch in the market. The I3 is the most complete watch. There are some differences between I2 and I3, but less differences between I2x and I3. Check the garmin site and you can compare watches and see the diff
