Ive been detecting from june with my 1350. 50+ silver coins alot of mercs. No half though. Oldest barber dime from 1906. 10 buffalos. 1913 the oldest. 5 silver rings. 14k plated medallion. 4 old tokens. 100+ wheats. British half penny 1921 if i remember. 500+ in clad. 1350 serves me well. Its good at picking up buffalos once you learn the hit. At the end of the season i hit some very popular areas for detecting. There gone over well but theres still some deep stuff. The standard coil gives me 6-8 inches, if i can use the dd i get 8-12. The first month or so i found nothing deeper than 4. Im sure theres room for a little more depth improvement and consistancy. I feel ive made great strides in learning the detector and working on my techniques. Im finding alot of old coins that are deep and thats what im looking for. I m a little short on rings and gold, but i havent really been looking for them. Thanks for all the tips everyone
