I must object strongly if you get a Minelab Excalibur put about $500 aside for when the sheeting on all the cables falls off and the company will not stand behind it and they have even admitted the problem or the cables so spend $1,300 on a piece of junk because minelab does not care about their warranties if you want a good detector with a good warranty go to Whites I have used Whites for decades and never had a problem but one time and they fixed it promptly thank you very much
I think you need to look real seriously at the Whites DFX, MXT or M6. For simple coin /jewelery relic and beach hunting the M6 IMHO is the best detector for the money on the market today. If you plan on doing some additional prospecting you should look into the MXT. If you want to dish out the money and get a machine that will do it all as well as any other machine on the market look at the DFX. It's only limitation is the skill of the operator to program it and get the most out of it.
