July 1983 --- Tesoro Inca --- The change for me to switch to 85% Relic / Old-Site Hunting.
I quickly swapped the 7" Concentric coil from my Mayan and started attacking the extremely dense Iron debris and sagebrush-choked ghost towns near me. Also concentrated on old vacant lots, overgrown old-use sites like Dance Hall and Picnic Grove locations, demo and renovation work, and the number of desired old coins.came at multiple rates! Ever since then I have maintained two or more favorite Tesoro models in my personal working Detector Team.
You have the old photos, but do you still have the good old Inca on hand?
