Woo3 seems to exaggerate height on smaller jumps but levels off on jumps over 12meters..
Recently we witnessed a couple of different guys doing 14-15m jumps on woo3 and everyone on the beach agreed that it was pretty accurate reading..
Also, woo3s got more consistent readings from what I have seen.
One of our guys used to put 4-5 woos on the board and then post the highest reading online.
With woo2 the difference between them on highest jump was frequently over 1 meter.
Now with Woo3s, the readings are usually within 10cm (assuming that the woos are mounted close to each other; you can still cheat by mounting them far from the center of the board, but the locals don't do it since it's seen right away)
