Their web site is truly awful, but, the software works well on a decommissioned Samsung Galaxy 10.
The app by itself I recall being quite inexpensive on the app store.
And we printed the targets at 8.5" x 11" for free. They sell nicer / bigger ones, which I will eventually buy.
You hardly need any space at all to run this setup. An old camera tripod, with one of these:
This heavy duty device holder has 2 clips - one on either side - and will hold smart phones and tablets. If you already have a tripod, use this holder for your device when you train. Holds smart phones in portrait or landscape modes. Holds tablets in landscape mode. Fits standard tripod camera...
g-sight.com
handles the target viewing. The voice commands and sound effects from the phone are fun, helpful, and intuitive.
Now, the
pistol used for this setup was a 'trick' ... it's a Taurus G3C which is striker fired ... *BUT* it has restrike capability.
...
This means: no racking between shots. Just pull the trigger. It's like a sort-of DA feel.
(You can make it 'SA' feel by short-racking the slide if you prefer.)
And the G3C takes Glock sights if you don't like the factory ones.
This isn't an expensive pistol and isn't even an awful pistol, so there is some irony that it never gets to see powder ammo.
Laser cartridges are definitely not all the same.
The G-Sight 'Elms Plus' has been FAR and away a better choice than all the cheapies we tried.
