D2 x10 sensors burning wrist

My watch”s green and red sensor lights are stuck on full brightness and won’t turn off. 

I realised this when I got a low battery alert this afternoon, when I only charged it this morning. 

The skin on my wrist now has 2nd degree burns, it is blistered under the sensor areas. The watch itself became very hot. 

There are many other reports of garmin sensors burning peoples skin. Recall the product, it is dangerous!!

will garmin customer service please contact me asap. 

it is NOT strap irritation, NOT a skin allergy or reaction, NOT a bacterial infection. It is the UV sensor lights, and they can burn you!!

  • It is the UV sensor lights

    I do not know what it is, but surely not the UV light. The green sensor uses light in the mid range (530nm), nowhere close to the UV spectrum, and the red light of the PulseOx sensor uses the near-infrared light, which is on the complete opposite side of the light spectrum.

    You best contact the support directly by phone, chat, or email - see the contacts for your region at https://support.garmin.com 

  • Trux, you are a garmin employee Troll.

    You say you do not know what it is, but then claim to know that it is not the sensors. You’d be better sticking to your first sentence!!!

    I think you must work for Garmin and you’re trying to smoke screen! 

    it is definitely the sensors, as that is the exact area of my burns, and that is where the watch is getting extremely hot.

    I have just put the watch on charge and both sensor lights, red and green, illuminate at full brightness and don’t turn off. The back of the watch, right next to the sensors then becomes extremely hot to touch. Hot enough to blister my skin, I will attach photos when I get back to my home computer.

    if it”s not the UV light itself, then it’s the housing of the uv sensors.

    People don’t generally get burnt from the light emitting from a domestic lamp or light bulb - but try touching the bulb with your bare fingers and see what happens.

    garmin - please contact me, and consider a safety recall immediately  

  • Sorry, not an employee, you'll have to contact the support if you want to get in touch with them. This is primarily a user forum. You may be lucky that someone from Garmin spots your post here, but I'd rather suggest to call the support in your region, to have your device exchanged quickly. 

    UV light is neither green nor red. And none of the sensors uses UV light. Read about it in the following article. I wrote I do not know what your burns come from, but I know it is not from UV light, since there is none. More probably from the heat due to a short circuit or from a similar hardware failure.

    Are the Heart Rate Lights on a Garmin Watch Safe for Skin? | Garmin Customer Support

    The light emitting diodes used to measure heart rate on watches that feature wrist heart rate technology are at a brightness level that is within published safety guidelines. The light emitted does not contain ultraviolet or any other potentially harmful frequencies. Light energy in contact with the skin is comparable to normal room lighting conditions and far less than the energy that a person would receive from sunlight.

  • Ok, so I will amend my comment. 

    it is not a problem with the “UV sensor lights”….it is a problem with the “sensor lights”.   

    The watch’s sensor lights became hot enough to have blistered my skin. 


    I am currently in consultation with the customer support team as to whether this aviation product is safe enough to be used in a flight deck. 

  • The majority of the forum posts about burning seem to be the result of a skin rash, some of which can apparently feel like a "burn". Regardless, I would try the solutions mentioned in this post:

  • I can assure you, with absolute certainty, that this was NOT the result of a skin rash. 

    The watch itself, specifically the area of the light sensors became too hot to touch. 

    This was a heat burn caused by the high temperature of the light sensors. 

  • Ah. Well, I'm not an expert nor do I have a perfect memory but I don't recall seeing much for sensors generating heat like that during the past seven or eight years that I've worn Garmin watches (including most versions of the D2). But I have read extensively into the testing that is required for devices, such as those required by the FCC and Industry Canada. If I was to guess, I would suggest you ended up with a faulty device that is shorting out and/or overheating. That's crazy that it blistered your skin. Was it a gradual warming or did it suddenly get supper hot and you had to rip it off?

    The D2 Air X10 is simply a rebranded Venu 2 Plus, with no hardware changes under the case. On the software side, the base software is the same for the common functionality with additional code added for the aviation apps. Given the popularity of the Venu 2 Plus I would expect to see other reports of overheating if this was more widespread. Will be interested to hear what the end result is.

  • I definitely agree with you that this is a faulty device. I started wearing Garmin in about 2007 with the Forerunner 205!! Never had a problem with any of them until 2 days ago. I absolutely agree with you, that a normally functioning garmin would never cause damage to skin, and that a rash, allergic reaction etc would be the most likely cause. 

    So yes, my D2 is faulty to be producing sufficient heat to blister the skin.  My current observation is that the heat is coming from the area of the light sensors. The device won’t charge now, and when I plug it in, it goes through its start boot up, both sensor lights illuminate, and then it shuts itself down. 

    The Garmin support team are being very helpful, they are considering my problem, and I’ll let you know what they think. 


  • sensor lights come on during charging, and won’t turn off despite ‘resets’. 


  • Immediately after taking off the D2.It was a slow burn!  I don’t think I noticed any discomfort until about 10 mins into the cooking process.
