Well its time for a upgrade .I love the Tesoro's , but I sure have been looking a lot at the FISHER F70 .I'm stuck between the Vaquero and the F70 any help would be be great.I mostly hunt for coins.Parks and old sites.With the Tesoro I have to turn the disc up to keep from digging so much trash and I fill like I could lower the disc and use a display machine to weed out the trash and still find the good stuff on the lower end of the scale.Thanks
