1) can check both individual lap time and lap accumlative time
2) just press one button to starting a new lap
3) dia. 30mm LCD panel with big size reading
1) vv easy to clear the old record if pressing the "stop" button twice accidentally
2) can not record the laps into "group"( for casio SWG200, laps are grouped and view as a "run" as dated)
3) no "est record", distance & energy consumption
ps. with both black & white marks ring / bule & yellow marks ring....
( I think it should be same "module inside" as Paco 爸 ching introducung before...)
