Nayi metal detector machine haath mein aate hi seedha khet mein jaakar search shuru karne ka mann karta hai. Lekin pehle din ki zyadatar nirasha galat settings aur galat technique se aati hai. Yeh guide aapko pehle din se sahi tareeke se shuru karne mein madad karegi.
Step 1: Ghar par machine ko samjhein
Bahar jaane se pehle ghar par hi alag-alag metal ki cheezein — ek sikka, ek sone ki angoothi (agar ho), ek lohe ki keel, aluminium foil ka tukda aur botal ka dhakkan — zameen par rakhein. Machine ko upar se ghumayein aur dhyaan dein ki har cheez par awaaz aur display kaise badalta hai. Ise “air test” kehte hain. Isse aap machine ki “bhasha” samajhne lagte hain.
Air test ghar ke andar karte waqt phone, laptop aur fridge jaise electronics se door rahein. Ye interference de sakte hain. Floor mein lohe ki chhad (RCC) bhi signal de sakti hai.
Step 2: Ground balance karein
Zameen mein maujood minerals bhi machine ko signal dete hain. Ground balance ka matlab hai machine ko batana ki “yeh zameen ka signal hai, ise ignore karo”.
- Automatic ground balance: button dabakar coil ko zameen ke upar-neeche (lagbhag 10–15 cm) pump karein, jab tak machine stable na ho jaaye.
- Manual ground balance: knob ghumate hue coil upar-neeche karein, jab tak upar aur neeche jaane par awaaz ek jaisi na ho jaaye.
Jab bhi zameen ka type badle (jaise ret se laal mitti), dobara ground balance karein. Mineralized zameen ke liye humne alag guide likhi hai: mineralized zameen par detecting tips.
Step 3: Sensitivity sahi rakhein
Sensitivity full karne se gehrai nahi badhti — balki machine bina wajah beep karne lagti hai. Medium se shuru karein. Agar machine shaant hai to thoda badhayein; agar baar-baar falsa beep aa raha hai to kam karein.
Step 4: Sahi tareeke se sweep karein
- Coil ko zameen ke paas aur barabar rakhein — 2–3 cm upar. Sweep ke end par coil ko upar na uthayein.
- Dheere chalein. Ek sweep mein 1–2 second. Tez sweep mein chhote targets chhoot jaate hain.
- Har sweep ke baad aadha coil aage badhein (overlap), taaki koi jagah na chhoote.
- Area ko rassi ya nishaan se lines mein baantein aur grid mein search karein.
Step 5: Signal pehchaanein
Achha target aam taur par dono taraf se sweep karne par ek jaisa, saaf aur repeatable signal deta hai. Ek taraf se aane wala, tootta hua ya badalta signal aksar lohe ka kachra ya zameen ka effect hota hai. Shak ho to coil ko 90 degree ghumakar doosri disha se sweep karein.
Step 6: Pinpoint karein
Signal ki sabse tez jagah dhoondhne ke liye coil ko “X” pattern mein ghumayein. Machine mein pinpoint mode ho to use use karein. Khudai shuru hone ke baad handheld pinpointer bahut kaam aata hai — gaddhe ke andar exact jagah seconds mein bata deta hai.
Step 7: Saafi se khudai karein
- Chhoti khurpi ya trowel se ek “flap” kaatkar mitti hatayein.
- Nikli hui mitti ko kapde ya sheet par rakhein aur use bhi check karein.
- Target milne ke baad gaddha wapas bhar dein. Kheton aur zameen ke maalik ki izzat karein.
- Mila hua kachra (keel, dhakkan) saath le jaayein, wapas na daalein.
Beginners ki 5 aam galtiyan
- Sensitivity full karke chalana
- Ground balance na karna
- Bahut tez sweep karna
- Coil ko zameen se bahut upar rakhna
- Har signal par khudai karke jaldi thak jaana — pehle signal ko samjhein
Safety aur kanoon
Bina permission kisi ki zameen par detecting na karein, protected monuments ke paas search na karein, aur bijli ke cable ya gas pipeline ke ilaake mein khudai se bachein. Kanoon ki poori jaankari ke liye padhein: Khajana khojne ki machine aur kanoon.
