I know this has been talked about a few times on the forums but I've never seen any type of response from Garmin.
Purchased a 2x Tactical coming from a first gen Instinct. My wife is still using her first instinct and the difference between the notification beep is crazy. It has to be dead quiet to hear the 2x and I'm finding myself relying on the vibration (which I'm nervous about because my 1st gen Instinct's vibration motor kicked the bucket and had to be replaced). Her watch I can hear from across the room. For a watch that was significantly more expensive, it's one feature that feels like a massive downgrade.
If there's any news on a fix or something that other people have done to fix it let me know!
