Hey Guys! I have a question for you experienced Minelab Excalibur users out there. Is there a big difference between the minelab Excal 1000 and a 2?? I have a chance to buy a new 1000 in box for $800.00. That sounds like a good deal right..... But im curious if you think that the 2 has new performace enhancing features that are worth paying for??? Or is it just green with a better battery? I appreciate your advice.
