Hello ... First post. I have been in the market for a new detector. After considering the Fisher F75 Ltd, Minelab E-Trac and V3i I have decided on a Whites V3. There is a local distributor who has an inventory of new warranted V3's that are upgraded to V3i's including wireless headphones for $ 1100.00. Other than the software are there any differences between the V3 and V3i? Also, what other coils should I consider. I hunt relics, coins and beach in the Florida Panhandle and South Alabama ... Thanks
