I'm with Dave on this one. Even though we have seen competitors zoom off towards a PowerFlarm target they saw climbing strongly, I am not sure this will turn out to be the advantage many wish for. I can't count the times I have ended up a thousand feet or so below a colleague climbing at ten knots to find nothing there - the thermal bubble had departed upwards!

My opinion is that knowing the location of nearby competitors is useful for both safety and tactics, but will impart no advantage if the information is available to everyone. I strongly oppose the adoption of the "stealth' mode for this reason.
