Increasing Coil Current.

Assuming that you could still sample at the same delay, increasing the coil current by a factor of 2 will give 1.12 times the range that you had originally. 4 x current = 1.26 times range. 6 x current = 1.35 x range. 8 x current = 1.4 x range. And so on until you reach 64 x current when you will have doubled the range. However, at the higher current levels, the switch off takes longer, so inevitably the sample delay has to be further back.
Increasing the receiver sensitivity by similar amounts will also give the same improvement. The down side is that electromagnetic noise is also increased by the same amount as the signal, so there is little benefit.
Eric.
