After getting a Nokta Makro Simplex+ from Kellyco in July 2020, I made an effort to test it out as much as possible to see how it performs in both beach and park grass areas. The Simplex+ was amazing! I was finding coins everywhere I went on every trip, and even some small toy cars & costume jewelry too. My best trip was on September 11, 2020, when I was testing out my new SP24 coil when I got a solid 44-45 signal and found a 10k gold women's diamond ring on the beach. I was ecstatic of course and thought the find was incredible just as it was. You can imagine the look on my face when I later went to a busy, trashy parking lot about a mile from the beach and found an almost identical 14k gold men's band about 3" under the grass on a solid 30 signal. What a day - one I will never forget for sure! The Simplex+ is like a coin & treasure "vacuum" - love that machine! Thanks again Kellyco!!
