Setting up the timing points for a swimming race is simple. In most cases you will only have to set up a finish line, but you have to differentiate between two types of finish line: on the ground or in the water.

A finish line on the ground you can time using the side antennas and the reusable passive tag. This type of tag is slightly affected by water so the closer the gap between the side antennas at the checkpoint, the more effectiveness you get in the readings.

If the finish line is far from the water but with sand you can consider using ground antennas.

If the finish line is in the water you should install a floating side antenna structure. Swimmers should wear the tag on their wrist and not on their ankle. Once they reach the finish line, they should touch with the hand that carries the chip on the floating structure.
