Got my land ranger 5 or six yeqrs ago. Has it been upgraded or changed since then?Why do I still get pull taps when using program 3.When I'm at the park I get tons of hits always showing number reading jumping all over the place.Would like opinion on this model and best settings to use.I've got to the point I don't dig anymore because of so many hits.I'll dig a repeating hit 4 to 6 inches check the hole and no hitin the hole or around the dirt dug.waste of time
