I bought 2 Whites Coinmaster Pro's 3 years ag
ne for me and one for my 8 year old grandaughter so we could hunt together and I could follow her to see what she missed and to hear what she was hearing when she found a target sound. It's very beginner friendly. It also has a 2 tone button which gives a low grunt tone for iron and nails and a high tone for all keepers from gold to silver. I was amazed at the clarity and precise readings of items below ground. I went to a park area that I have hunted a few times with my Ex2. did not expect to find hardly anything. In the first 1/2 hour I pulled 3 Mercury dimes out in a bout a 10 foot square area ...all at about 5-6" deep and the depth meter was right on! I was awestruck. They rang out clear as a bell .. this machine is a beast on silver. The pin pointing is dead on...but all concentric coils are like that.
The two tone or Tone I.D.is awesome at differentiating Ferrous targets from good targets giving a low ground for iron and a high tone for keepers!!! Just like the Garret AT Pro! It has a loud speaker and a 1/4 jack for headphones. It has notch discrimination for pull tabs only..Smart Notch, which works perfectly. You can notch out Nails,Foil,Nickels,Pull Tabs. This machine has functions found on $400 machines. For AROUND $230 I actually have nothing I would change or improve on it except for a higher frequency for Gold detecting but that comes with a much higher price for a detector. Our Ex2's go as high as 16Hhz the Coinmaster is 8.. it will still pick up medium to large rings and silver rings no problem!
It's built as good as ant expensive detector and the screen is very easy to read and understand. I am going to buy the both of us the DD coils which will make this machine even more awesome!!! I love use this mach. 50% of the time. Every new site I use this first. If items are 5" or less I will use it the whole hunt! It is so lite you can swing it till the cows come home and not get tired. I'm 6 foot and the long extension of the shaft is perfect for me.
I have been hunting for 20 years starting in 1996 with a 1975 box Coinmaster and in 2002 bought an Ep XS and when the screen crashed on me in 2013 I bough a used Ex2 off eBay for $480. Then I found a guy in England who makes after market new screens for $75 and now my XS is working like new again to! I love my Explorers but I also love this Coinmaster Pro which is in my car 24/7. It's short length setting is 46".. if this is too long still for your son they make a short shaft accessory for children. Hope this helped! John
