This is a summary of my experiences with the Safari.
I've had my Safari almost 2 years now. I detect at least 10 hours per week, mostly in the woods. Personally I don't feel it's a turn and go machine and it took time and a LOT of holes to start understanding good tones from bad. I realized quickly that creating my own custom settings made the machine easier to use than the preset modes. Set your target parameters relevant to hunt/site and adjust sensitivity accordingly. If most of the targets you normally dig are at 4-6 inches try running the sensitivity at 12-13 for 30 minutes and see how it works for you. First time I set the sens at 14 the machine was stable, less chatty and tones were easily discernible and I was still digging targets at 8-9 inches. I've gradually increased sens as I gained experience with the machine, I now run 18-19 and have recovered very small targets at depths to 14". Be forwarned that running sens at max you will get falsing, Small sticks, roots etc. that hit the coil will even give a fleeting tones and the machine will sing songs but with experience you'll easily learn what to ignore. Ever notice that when a target gives you multiple odd VID #'s (38, 27, 16) it's usually junk? I've found 90% of the time it is and move on to find another target. Now if I get multiple VID#'s that are 32, 34, 30 or 26, 28, 25 I will always dig it because the numbers are in the same neighborhood. I know I've let a few good targets go by by adopting this rule, but I also dig less crap allowing me more time to find other quality targets.
As far as the Safari popping a high tone over an iron target... that's not uncommon for any detector be it an Excaliber, E-trac, Cibola, Garret, etc... they will all pop a high tone on iron occasionally especially if the iron is deep, same goes for small square nails. An old square nail can sometimes sound like a deep silver coin, until you get closer to it or get it out of the hole, those dam square nails get me every time. I can usually tell now with a good deal of certainty from the tones if it's iron, it will often only give you that nice 38 sound one way or only from a certain angle. As iron degrades it's properties change and you get falsing, that's just metal detecting. The sound of a coin next to iron will make a slightly cleaner more repeatable sound than just straight iron falsing In my experience. The VID #'s are just the machines calculation of the combination of the minerals and metal below the coil. I use my ears more than my eyes now when using the Safari. Sometimes a tone or # that you think is a winner is a loser, and vice-versa, but again that's metal-detecting. Fatty Indian Head pennies will ring at a solid VID of 18. If the machine told you exactly what you had 100% of the time I'd find the hobby boring, like seeing your presents before Christmas.
I would have to agree with coil comment, the stock coil is great for NON-TRASHY open fields, parks woods and beaches. Using it in trashy sites takes more patience and a good understanding of what you're hearing. I am going to get a smaller conical coil this winter to use at trashier sites. Conical coils IMO allow more accurate pinpointing and the ability to separate multiple targets by raising the coil and letting the cone tip "feel" around the target area. The Safari's Double-D stock coil does not scan in a conical pattern, which makes target separation more difficult IMO. It covers a wider spectrum than concentric/conical coils so the probability of picking up multiple targets increases. (see handy dandy diagram I attached.). BUT the Double D coil offers more depth and scans more real estate with each swing, so there are advantages and disadvantages to each coil style. Someone made a comment on battery life, I have both a 1600 NIMH stick and I have the stock sleeve for the AA's. I get about 10 hours out of either battery setup which is pretty good because I don't use headphones so the battery gets more of a workout. (yep I'm one of those non-headphones guys, but I hunt in remote areas so I'm only bothering the wildlife.)
Some of the peeves I have with the Safari. #1 - the foam, porous, spongelike handle... who was the genius in engineering that figured a sponge handle is a good option for something that involves dirt, mud and wet grass? Helllo? Peeve #2 - The cheesy rubber battery hatch cover.... did they try duct tape first and then settle on this design? Did 5,000 Safaris come off the line before someone realized they forgot about covering the battery? "Hey Joe lets just screw these non-fitting rubber flaps over it and call it a day." My 4 dollar Walmart flashlight has a better battery cover than my 900 dollar Safari. And my final peeve.... back in 82' I had a 14 dollar casio digital LCD watch that had a little button on the side. If you pushed said button it illuminated the numbers on the screen... it was amazing. Imagine being able to read the display on the Safari in low light conditions? Wow, now that's some cutting edge technology they could have put on the Safari,.
OK, if your still reading 10 points for you. IMO I don't think there is any machine free of anomalies, falsing, or design errors, there are trade-offs on any product, be it cars, corn flakes or metal detectors. I had a difficult time with it during the first 4 or 5 hunts so I'd say about 30 hours in I had begun to understand. Having had my safari for 2 years now I wouldn't trade it for another machine. The learning curve was steeper than I had anticipated, which was very frustrating especially since it was advertised as a great machine for beginners. Now that I'm over the curve I am thoroughly enjoying this accurate and deep detector. I've found colonial coins, buttons, buckles, seated coins, capped busts, draped busts, reales, and many other wonderful finds over the past 2 years and I am still learning the machine. If you stick with this machine until you are dialed in you will reap the benefits.
Oh and make sure to pop the coil cover off occasionally to clear out the debris that is between the coil and protective cover.... This made a WORLD of difference for me after I began getting a lot of falsing and didn't know why... it was caked with leaves, sand and dirt. Happy Hunting.
