I am not a dealer for Teknetics but the T-2 that I had was a great machine.(I usually purchase new machines so as to be familiar with them and have an idea of their abilities).. Being a relic hunter and an occasional coin hunter, I thought the machine was great the way it was..Bottle caps was never an issue... Depth was great and mine was hot on small brass... I pulled targets from heavily hunted sites...IMHO, Best to all, Richardntn
