I am new to this forum but I have owned several detectors over the years. I currently use a Fisher CZ-6 and a Minelab Explorer XS. I started with a Fisher and always plan to have one around. I have also owned a Bounty Hunter, a Fisher 1266, a Tesoro, a Garrett 2500, and a Minelab Sovereign. For coin hunting the Minelab and the Fisher are about equal. The Minelab has probably a little more depth but the Fisher is very close. I like the display on the Minelab especially since I am detecting for CW relics. I can look and see where the target is displaying and be about 75% sure of what it is before I dig. If you decide on a Minelab Explorer be sure and get the book "Mastering the Minelab Explorer" by Andy Sabisch. The learning curve on the Explorer is a little steep and requires a lot of concentration. Any detector that you get accustomed to, and have faith in, will do the job. Buy it and use it often!
