Number one I do not like Pro Coil it is alright, but using the SEF coils 6X8,10X12 will make any Minelab detector a much better hunting experience,Why do you say, because it helps stop digging those IRON nails by 90 percent while still getting pro coil depth and it will make pinpointing much easier.
First thing you after putting batteries in your detector,Set to high trash,sensitivity to Auto until you get more time on machine.
Now standing in the place you are going to hunt you must find clean ground.Go to all metal,find a clean spot and noise cancel with COIL ON THE GROUND or you will lose depth.
Now set your Disc.I would recommend about 25 since you are new to Safari.
Start hunting and do not look at the target ID,You are using your ears to listen to the NULL not the tones.Why because all Minelabs work better accepting trash than rejecting(the NULL) this is slow recovery before threshold comes back.You should always pay attention to the Null and when Threshold comes back all the time or you are searching ground with the Safari/Etrac with detector basically off.while listening to recovery of null this will set your swing speed depending on trash content or how much Disc. you are using you may be hunting at crawl do not worry you will snipe coins next to nails.Pay attention to the NULL.
Quit looking at that target ID you are not ready to use it yet.Now keep hunting until you find a smooth sounding target that repeats from two directions if it pops, crackles,nulls_you are still listening to that null right? it probably is a rusty nail but if it sounds smooth still.Now look at your target ID it should not be bouncing that much also decide to dig.
The best way to use a Safari is all metal but it drives me insane.So I normally hunt in Stock Jewelery and dig repeatable targets above 20.Remember as I stated earlier Mine labs are better at accepting targets than rejecting, the lower your Disc the less nulling this will make you able to pick smooth signals out of trash,speed up your sweep,And limit the dead ground area caused by Nulling.You should be listening to hear high coin tone before even looking at target ID.
The Safari is equal to any Detector on the market at this time.If there was a better one I would buy it.I have been waiting for almost 2 years for a new improvement not happened yet.
Like all detectors they are stupid.They are calibrated for coin sized objects.The target ID is just a guide if it does not read accurate get over it it will read high enough for you to decide to dig.
Screen locking up,a lot of this will go away with getting rid of pro coil.Lowering your disc will help also when using Pro Coil.Think about it you told Safari not to accept anything below 30 it locked up for a while because you have not found another target above 30 yet.
