Hummm…I guess I’ll have to give it a good going over and check for cracks. I’ve had this S about 8 months, seems to working ok. I’m not an expert yet but, it has done well at the beach and parks I’ve searched. Some parts of the park I can’t detect because it sounds like a band full of flutes playing different songs!

I am a reader and I have read a lot of articles about guys putting 12” coils on these and almost doubling their depth and 5” coils to find smaller gold type pieces. My biggest concern was how this unit operates. Aside from the newer features (some I could live without) are the detection algorithms for discrimination still the same? I was hoping the older units operate the same as the newer ones just without all the extra bells and whistles. But then again technology does evolve. Are the coils made today better than coils 10 -15 years old?
