"Is the safari and a good all round machine..." Yes, unquestionably.
"If I don't care about some of the extra discrimination options and plan on digging most signals..." Well, let me go out on a limb and say that you will stop digging 'most' signals REAL fast. Theres simply too much trash in the ground in most places. Discrimination is important for most types of common metal detecting. I'd wager that if you stay with the hobby, you will crave more information from your machine.
"will the Safari be a good enough machine and will get similar depth as the Etrac?" Yes, probably. Theres a LOT of factors affecting depth, not the least of which is the user. As you get better with any machine, your depth and depth id will improve. At the least, given a same level of user skill, they are very close.
"do you thInk it will really pull things out of heavily hunted areas like what I read?" Yes, but you will have to do your part as the operator. No site is ever hunted completely clean. Many (most?) of the sites that I hunt, I sometimes just wonder how my finds could have been missed by all the hunters that I KNOW preceded me.
Your thought process sounds a lot like what I was thinking when I re-entered the hobby after a couple of decades out of it. I was sold on FBS too but didn't want to commit so much money until I knew more. That's why I got the Safari. If you have been reading the older posts, you will know that it is going to take you some tens of hours with the machine to get a handle on using it well. Most folks say 40-60 hours. I scoffed at that, but it held true for me; sometime about 50 hours in something went clik in my brain and my finds went drastically up and my trash went drastically down. The only insight I can offer to speed that process along is to Trust Your Machine.
Now, what are the downsides of a Safari, a question you should have asked;
- the aforementioned learning curve
- cost
- can drive you crazy with all the symphony of tones it plays. but in all that racket lies Information, and that's what makes finds.
- it isn't waterproof. Do Not use in any depth of water at the beach. I used mine in ankle deep swash zone, dropped it and barely caught it before it went splash. scared the crap out of me and I never went beyond damp sand after that with it. carry a plastic grocery bag with you to the parks/etc in case of a surprise rain shower and you should be ok at that.
Secure a copy of Andy Sabisch's book on the Safari, read it then go back and Study it. It will help a lot.
You didn't ask, but its my opinion that if you want FBS, its either Safari or CTX. No reason except price to get the middle of the tech. If you KNOW you are going to stay with the hobby for years, I'd advise skipping the Safari and going straight to the CTX. (many reasons, but the Target Trace feature [which the eTrac doesn't have] is worth the price). Nothing wrong with an eTrac; just my opinion.
Remember that you will need a good pinpointer too; my fav is the Garrett Carrot fwiw.
