Hi, am considering buying the Garmin Instinct 3 Solar. The chipset is the same than in the forerunner and both have same Multi Band Dual Frequency SatIQ GPS. In fact both watches are built using same tech. Just different design with additional solar battery in the Instinct 3. Am not planning to post on the GPS Team Challenge . Although not tested , can you advise if in your opinion the GPS speed results from the Instinct 3 could be comparable to the Forerunner you have now approved ?

If you are not posting to GPSTC, it does not really matter much. I am sure if it uses the same chipset as the 965 it should give similar results. I am sure I would be happy with the results from it for my personal use.

The main problem here is if you want to post to GPSTC. The watch you are considering may have great GPS data, but it is quite an effort for it to be approved so not really worth it unless you are very committed. It is just easier to get an approved device if you are buying anyway and want to use it for GPSTC.

My partner and I have been using Gamin watches for a while and had button failures on 2x 935 and 1x 955. The 955 failed within a year and we managed to get a credit towards a new watch under warranty. Forerunner watches are rated to 5 atm. Currently using instinct 2's which are rated to 10atm so hopefully better button design. Fenix range are also rated to 10 atm.

About 10 years for me with no button failure with mix of chlorinated pool water and salt at least 3 times a week. I doubt the pressure rating would change this failure. Not sure what is causing it in your case. I do nothing special with mine to care for it.
