I recently purchased the Instinct 2 (Solar) Tactical at our CANEX. Been wearing it for several weeks and as of late experiencing minor burns from directly under the green sensors? This normal?

Contact Garmin Support directly if you believe it is a burn.

However, it is more likely to be contact dermatitis. Remove the watch for a few days and clean the underside. Wear it on the other wrist if you still want to collect 24/7 data. Going forward, ensure you clean and dry under the watch at least daily.

Acknowledged and sincerely appreciated Sir.  I’ll give that a try as I do like the watch particularly for its many functions including Applied Ballistics and Jumpmaster.  
Again, thanks for taking the time

Totally normal, skin irritation I take it, no way the LEDs can burn you.  However I get hem all the time, swap between my wrist and ankles - kidding no its not normal.  Hopefully Philipshambrook's post will help. 

Hoping it does as well Gonzo.  Makes more sense it’s a dermatitis issue albeit the wrist blistered. Not a show-stopper, just uncomfortable. Anyway appreciate the feedback
