I couldn't wait any longer....
So Andrew and i went at a high tide to Devonport beach so i can test the Excalibur while he went over dry sand.
It took me about 20-30 minutes to get used to the machine. then the fun begun. spent about another hour there going up/down the "washing board" - that is what we call wet sand slope down to low tide mark.
Got Silver earring and some coins.
Then close to low tide - about 11 pm we went to Takapuna to try bottom of the "washing board" and ankle deep water :
Got a Silver ring :
So far not bad for a first time with Excalibur.
Stay tuned for further updates
