don't froget about "Memory probe" from Dungeoneering - Fremennik Sagas.. it say "Memory probe: Make sure your sounds are on and turned up. The current memories on the probe (seen above) do not help with finding the correct spots. Place your probe where the circular cursor blinks the fastest and emits a slighly higher pitched pulse. There is an area around the correct spot that will still blink and emit a pulse, so take your time to find the perfect spot. Do this three times to complete the memory probe" how does he can? lol
