I've only been detecting for a couple years. I know I have more to learn, but I do have a fairly solid understanding of what I'm doing. I just unboxed my new Safari today. I did my homework. Watched every video on the net. Read every review I could find. Downloaded the owners manual. Even picked all your brains about quality and functionality. I wasn't expecting the surprises I found. First, the face covering over the LCD is a THIN stretch type film!? I have the same crappy membrane over the face of my ACE350. Honestly, I did not expect that from a $1000 machine. The cheap build quality of the ACE350 is what inspired me to by my second detector, a Fisher F70. My second disappointment is target ID. Where I live, the world is currently frozen solid. You couldn't dig a hole with C4! I know air testing is not reliable, however, It's all I got right now. I wasn't so much concerned with depth, as much as target ID and audio feedback. I put the Safari into Coin Mode, auto sensitivity, and noise cancelled. I air tested all my silver coins, both US and Canadian. They all read 38. I thought, Okay...they're all silver? Then I broke out the clad. Much to my surprise, a clad dime also ID's at 38. Same with a clad quarter. Even the Canadian clad reads the same. I repeated this test in all 3 programs, including 'all metal' and got exactly the same results! I even define my own settings and descrim patterns, but to no avail. A wheatie looks like a silver dime, and clad quarter. I went a step further and pulled out my F70. Put her on the bench next to the Safari, and did the whole thing again. My F70 can properly ID a dime, a sliver dime, a silver quarter and a clad quarter. Each has a separate ID. Each makes a distinct sound. Through experience with my F70, I was very successful in ID'ing targets by sound alone. I don't see this with my Safari. Sure, it 'says' coin, but it lumps everything together!?!? I don't like that. I have 30 days to make a decision on this unit. There is no possible way, the ground will thaw before then, so a legitimate field test is out of the question. These numbers I'm getting....is it a result of poor air testing? Or is this the way a Safari operates? Because if it is...I don't want it. Any knowledge you could share would be greatly appreciated!
