The XP Deus costs $799 without the remote control ($1520 with!), the most common version has a 9 inches disc.
The Tesora Cibola has a disc of 8 x 9 inches.
If you compare the tests on Youtube, you will see that the XP Deus is much more complete: more reactive, offers more tone to differentiate the types of metals, allows to rotate the disc to refine the search.
The Tesora, it is much cheaper, since it costs $361, or $438 less and has a remote control integrated! If it is less reactive, it is equally competent to spot metals but to some extent.
The XP Deus has a software that updates itself. The Tesora has a static software, no evolution possible.

So basically for $438 more (even $1159 if you want a remote control to go faster in the settings), you have a more reactive device, which finds 2-3 inches deeper, which makes it possible to better identify the nature of the metal and which makes it possible to go faster in the scanning thanks to a greater reactivity.
However, it is known that most of the catches are made between 0 and 8 inches of depth. So XP mostly saves time in sweeping and digging because you can better privilege precious metals and moreover eliminate ferrous. The remote control will maximize this time saving.
The presence of a battery is a bit problematic, in the sense that you need an energy generator in the event that you do camping to keep your search in a distant region of home or abroad.
