When I first used the Explorer series it was necessary to hear an ultra deep target so I could compare the sound to other detectors I have used. It really helped to go to IM-16 and search for a very faint deep target as indicated on the dept indicator and modulated sound. I then just focused on that faint target and adjusted the threshold up and down to see what happened. I then did the same with sensitivity, audio gain, deep/fast ON/OFF and Normal sounds vs Audio1, 2, 3. This way I was not dealing with air test or targets I have in a test garden. That early test laid the foundation of how to adjust the detector. I will still find targets that are ultra deep and play with the adjustments to see what produces the best signal such as sweep speed, noise cancel, and have found there is a best sweep speed that is not too slow or too fast. It is a very comfortable one for me but a target will sound better with the correct sweep speed. Sweeping the target from different direction will make a huge difference in many instances.
Someone asked about headphones and I use Gray Ghost Originals, have the stock headphones, some Whites, Uniprobe, and other that are really not designed for metal detecting, and also hear some good reports on the brands of the sponsors of the site. I like volume controls on each ear which is not what I have on the Gray Ghost but use them as I can really hear faint sounds with them. Our individual hearing is so specific that I think we really need to test a couple of different brands to see which ones are best. I have very poor hearing in one ear at high frequencies and not so bad in the other. I need volume controls and would love to have tone controls for each ear. In addition they can really fit nice and be comfortable in hot weather or weigh a lot and constantly need to be adjusted. I do plan to get a pair of the Sun Ray Pros as they have very good specification and as I said want volume controls for each ear. I think there are some really top brands out there that other can vouch for but for me the headphones are extremely important. I am a testing type of person so have taken several pairs to the field and then tested them on deep targets. The headphones, for me, are a world of difference in what I hear. With the different headphone I think can change the setting of the Explorer since I hear a lot more with one brand than another. It is fair and important to realize that our hearing is so specific that the ones I like best may not work best for someone else. I am not trying to doge the question but know that our hearing needs to be matched to the headphones.
