coil DETECTEUR PULSE INDUCTION

[AMINECASCADEUR]

hello everyone, I'm trying to make a metal detector coil, I found these dimensions in this geotech1 blog, 20cm coil, 0.5 mm2 enameled wire, 31 turns, the inductance will be between 350 and 450?H, and the resistance Almost 2ohm, It's Perfect; My question: can someone help me to make a 50cm head with a 0.5 mm2 enameled wire, with an inductance between 350 and 450?H, and resistance 2 to 3 Ohm, because I don't have not an inductance TESTER, in your opinion with a 0.5 mm2 enameled wire to find These resistance and inductance values, how many turns to wind?
