Hi tincan302, Don't know if it's relevant but I spent 29 mo. on "Tin Can" DD746. I also, along with you and oldknifemaker am 78, and have enough Arthritis and other ailments to have gone to Tesoro for a lighter machine long ago. I've been digging since 69. Tesoro was the very first to come out with a machine lighter than all the rest, and I would have probably had to have given up detecting had it not been so. Oldknifemaker told you right on about the Compadre! I especially like it because most of the time I "Sling" it over my shoulder as a spare and use it with the 5.75 coil when I happen to walk in on a really trashy spot while using one my other Tesoros'. Oh yeah, Its light, as are most all the other T's and they get the job done while keeping the fun in detecting!. HH, Charlie
