Hi Alexismex.
Last weekend i receved an original Deepers MF (that have all items show on the pictures), that looks the same has the Deppers 8. The only deferent i can see, is that Deepers 8 have an LCD meter. The rest look to me the same.Next weekend i will have time to take many pictures from Deepers MF (10 DD).
By now i think the most important part is to have good details of the pcb traces and components placement.
I don´t think that a conversion from Deepers MF to Deepers 8, will be to much complicated.
By the way i had just an air test with a coke can, and hipersensitive coil, adn results was almost the same you got. Looks like a good machine.
Another function that i did like, was the way you can shift frecuencies, very easy and also helpfull to get te best sensitivity you need for the target you want to find.
Inductance is the same has you, 285 uH and 2 ohms for the hipersensitive coil.
I wil also like to make a smaller coil,that is also easy, cause the coil is a 4 pin standar conector.
Well lets keep in touch to share more informatoion about this detector, that for many peole looks like a mysterie cause the is not to much review information on the net.
Kind regards
Nelson

Soon i will post the power supply i must draw from paper to Splan,
I do not have actually a camera...later .
For the performance very good in neutral soil... with 10 inch coil.... air test 85cm .... inside ground 70 cm.for a alu-coca-can ....much much better than pulstar....If you see the schematic ...you will see a small " Deeper-secret
" to give the punch for the sensibility ...you must use + 6v and -12v for the Op's.... if you go to a more conservative approach with +5V and -5 V or 6 and 6 you will loose easely 10cm 
for the alu can and proportional with bigger coil ....
have goods feeling all the forum.
