Ok it is time to make the decision and take advantage of any Minelab Christmas giveaways. Any thought on X-Terra 70 vs the new Explorer, especially in regards to Electrical interference since this machine will be used primarily in the cities and suburbs? I have an Excaliber and a cz-20 for the beach and the outback, but both suck in the parks and construction areas around the built up areas. The Excaliber is useless because of interference, and the cz-20 is badly affected as well. I have been a Beach and Water hunter for the last few years and have not even wanted to go inland but I got the bug again.Any thought on which machine is less likely to have interference problems? I heard that the X-terra was virtually immune to that but I don't really believe it! How have you found the Explorer to be in the burbs and construction bulldozed areas loaded with junk?
