I need help. I use yo far GT31 on one arm and GW52 on other, just for compare.
When I ride I see that GW52 showing speed (actual speed), but, on the coast when I stop, he shows zero, and GW shows max speed
What do I need to set up to see max speed and 10sec when I stopped to look on gps

So far my setting is like that

Logging = 1Hz
Min speed = 1KT
Unit = NM
GMT
Speed avg = 10sec
Speed genie = 25 KT
action speed = speed
spd font = big
spd history = ON
scroll sec = 2sec

and what is the difference between small and big font becouse I don't see difference
and what is difference in Action speed between speed/avg

thanx in advance
