It is too cold to detect right now and I was bored so I made a few spreadsheets. I was curious how things like the RX gain and the TX boost affect depth so I made some spreadsheets and ran some air tests. The listed depth was where I could get a repeatable signal with a fairly accurate ID. As you know there are many ways to adjust the V3i so take these with a grain of salt. The tests were done with nothing discriminated out and were done indoors.
