Guys use the search function this topic has been flogged to death and then sum.............the swannie readings r always low due to location & the Ocean reef and rotto readings are high; again due to location as for woodies Laurie has already informed us that it's location isn't ideal.
Your best bet is to gain a bit of weather knowledge and how it affects the spots where you want to kite/surf/sup or whatever.
Oh yeah, you're right Weta, there have been a few similar topics posted in the past.
So, the results appear to be affected due to the actual positioning and perhaps the age and condition of the "reader" itself. Perhaps the Swanny one needs a bit of lube (If they cant find any lube, there's probably a fair bit in those sand dunes in Swanny)
Cheers
