We gave this to our grandson, aged 7, for his birthday. We did what the review said and threw coins in the yard prior to opening gifts. He immediately went outside to “hunt”. He was thrilled when he started finding coins. He played out there until dusk. He has hunted several more times. Found an old railroad spike, rusty screws, bolts, nuts, and he never tires of the thrill of the hunt. Highly recommend! Lightweight and very penetrating in the soil!
