BS-25 Calydoan RUSH-effect question

hello experts,
please help a bit. does the effect "RUSH"detail of this spirit mean that i need TWO green/emerald gem symbols on my field, to activate?
and not just one green gem symbol? i have the card and also looked at the wiki scan and there are indeed TWO green gem symbols printed in the effect.

Your eagle eyes strike again, Bolmeteus! Calydoan's RUSH effect indeed requires two Emerald Gem Symbols to activate, not just one. I went and made the necessary correction on the Ultimate Battle 02 thread. Thank you once again!

ok, and i thank YOU! because without your work, i could not experience my BS import cards like i do:-)

Be clear about this, the two symbols doesn't means require a card with double symbol on it. Just simply "as long as there are 2 symbols on the field."
