Hi Steve,
Wanted to share with you an issue you may have when detecting the sands of Hawaii, I found this out this past Sunday when hunting a California beach.
No matter how careful you are with keeping sand away from the shaft it will be in there and be almost impossible to get out, The find ocean sand will find it's way in there especially the cam locks boy was it a nightmare getting the find grit out even after washing down the detector and shafts..
In fact, Scratched the shafts that will be the last time I take the ATX to the ocean. Fresh water lake sand isn't as fine as ocean wet sand so lake sand can be washed off allot easier, If you can hip mount your detector for the ocean wet sand.
If not, Prepare yourself for punishment.
If anything, Enjoy your time there and take another detector if you can't get the ATX hip mounted in time.
