Dear Lakeview. Do you currently own a different metal detector? I have Garrett's Infinium LS, and it is awesome. However, there are a lot of differences than the average detector. I may have a lot of pointers for you, but I don't know where you stand on the issue of using a metal detector. One thing is to bring multiple sets of spare batteries, cause that thing will suck the juice out of them. Also, I use rechargeables, so my cost of use doesn't outweigh my return in treasure. Another funny thing is the volume through the headset. On land and in the water, the volumes are vastly different because of the way sound travels. There is a lot of great stuff on the internet about how to use it, and where to go and such.
Best of luck.
