I think you're on the right track. There are a variety of targets than will give the 95 reading. I've dug a lot of metal eraser bands from broken pencils as one example. I'd strongly recommend digging pretty much every thing that sounds good and pay attention to how the trash sounds. After a while you'll recognize targets that don't sound quite right for a goodie or trash, but every 5th or 6th one will turn out to be a goodie. I hit one of those with my DeLeon a while back that I walked away from, thought about it a moment, when back and retrieved a small, silver charm off a bracelet. Always dig when you get a signal that bounces through the coin indications with a trash reading or two mixed in, as these are quite often coin spills. As to more time in your test garden, that won't hurt a thing, but you'll also learn pretty fast by hunt, hunt, hunt, and dig, dig, dig. Takes a lot of patience to hunt through the heavy trash, but you're right about that. You may find it beneficial to use the 7" or 5.75" coils, as well.
