I just got my fourth Explorer yesterday. I have spent the last seven years trying every detector made. I always found myself comparing these detectors to Explorers so after many thousands of dollars, I am back. I bought a solid used Explorer 11 with a Sunray x-8 coil, but no Sunray probe. I quickly remember why you need a Sunray probe- these Explorers are DEEP. Today I took my new toy to a park I have hunted hard the past four years. What a test and the Explorer passed with flying colors. No great finds(seven wheats, one mercury dime, and one buffalo nickle) All were in an area I have stopped hunting because of lack of finds. All were 8 to 9 inches deep. Now for what I like best about Explorers. I dug hardly any trash to speak of. Some call the Explorer slow and plodding, but it goes deep for coins and is in my opinion the most accurate detector made period. I am done spending my money and am here to stay. R.L.
