Minelab Tones

[OxShoeDrew]

Hello Friends,
You might know I'm a T2 user. I really want to buy the new Equinox 800. I'd like to ask a question of you Minelab users (assuming the etrac and Equinox have the same sounds). The T2 has a great tone choice called 2+. It allows you to hear depth, strength, whether iron or not etc BUT- you hear only one tone per pass over the target. The tone has an infinite amount of sounds, but it's always one tone. The Minelab, on the other hand, seems to produce multiple sounds going over a single target. Something like
blup BLUP BEEP BLUPE blupe My question- why are there multiple sounds over a single target? Do they give you more info when you learn the language?? Thank you!!
