Thank you Steve, Thank you Kostas for your advice βΊοΈ. GPX series of MineLab are expensive. I found some fields that I'm sure there are valuable things in it. Also we are sure most of them are bronze. One of the fields is a cave and objects are embedded deep inside the walls. So with these comments I'm going to change my mind about Gemini3 and think about Garrett ATX, OKM Pulse Nova or a used Vallon minehound π€
