I recently bought my own SCATT Basic and while I haven’t spent a lot of time trying to work it out, I haven’t been able to get the red dot to show up while calibrating. The target is centered in the camera and visible. Is this just an issue with lighting? Thanks for any help
Hello there,
Probably has to do with some slight lighting shortcomings
The target should be
evenly illiminated with the intensity of at least 1000 Lux (if you are using a smartphone feel free to download LUX Light Meter or a similar app). Generally speaking, we recommend using “warm” LED lights (2700К) or regular in-candescent or halogen lights, as those are sure-fire when it comes to lighting
(Just in case) Please, make sure that you've printed out the target in regards to the
precise physical distance. The distance should be measured from your sensor's lense, rather than from where you stand - taking into account the fact that your extended arm/gun will shorten the distance during the actual practice session
If we are talking home practice, try relocating your paper target to a
white wall.
Sometimes darker walls are detrimental to the sensor's FOV, since it has to see more white "blank" around the target's black circle.
Below is an
example of a poor choice in regards to the background (note how dark and reflective it is)

In case a white wall is not available, you can always add white background with blank office paper and end up with something like this:

Also,

This is our Iris diaphragm. It's
designed for outdoors to offset
extreme sunlight conditions
Generally speaking, it should
not be used indoors or at the range, because it interferes with the sensor's ability to see the target when excessive sunlight is not there. Thus, take it off if you have it attached at home
