THE SPYDER X
Unlike the black enclosure of the Spyder 5 the Spyder X has a white one (yes i liked the black one more) that has a light sensor right at the front.
As with the Spyder5 the SpyderX also features a tripod mounting hole.
To use the Spyder X you will need to remove the cap as seen above (the cap also acts as counterweight).
According to Datacolor their new lens-based color engine technology doesn't only provide more accurate readings but it's also faster at doing that.
Here you can see the Spyder X right next to the Spyder5 which I’ve been using for monitor reviews.
