Treasure Coast treasure. OMG, did I just find a priceless piece from the treasure fleet of 1715? Chill Bill Published on Nov 18, 2016 I think I have found a relic from the 1715 treasure fleet off of Florida's treasure coast. Tell me what do you think.. I'm back to the Treasure coast with my Deus XP and Excalibur 2 and I just found something on day 1. Take a look and tell me if I'm dreaming. A treasure captain says it looks right for a wreck artifact... mind blown! Two more days of treasure hunting, more videos to follow.
