I own 3 machines and i have a use & place for each one.I have a Minelab Sovereign,,A Tesoro Cortes & a Whites Surfmaster Dual Field..I do a lot of Beach Hunting and can use all 3 for the Beach .If i have been to the same Beach say 3 times through that week i will go back Monday morning and use my Tesoro Cortes.I have already checked the beach so on Monday i'm not looking to go really deep and the Cortes is good for 9" anyway.The Cortes is like swinging a feather compaired to the Minelab Sovereign with a 15" CoilTek (WOT) Coil..If i am going to a New spot to hunt,,Beach or Feilds i take the Sovereign because it has reached 19"inches deep for me..There are some guys on YouTube getting depths of 21" Plus inches.. The Whites Surfmaster i use for water..I remember when i first tried the Cortes after owning the Sovereign for a few years..I was at a park hunting and i had a grin on my face because it was so light.!..I couldn't believe the weight and how good it would pinpoint and hit silver..I would reccomend the Cortes or Tesoro to anyone,,No one has a Machine in that price range and a Lifetime Warranty.!!..I'd like to see Tesoro or an aftermarket place make a few larger coils to see if it was possible to get a bit more depth..I am really happy with Tesoro......John
