Suspect it's just my ignorance &/or ineptitude but I can't seem to figure out how to purchase a TF-PRO Kit...?? (Btw, have been using TF-100 for 3 seasons now & LOVE IT!!) Brief backstory is that a friend is installing an inground 'plastered' pool & I recommended he purchase the TF-100. Then, I saw a few 'mentions' & pics of the TF-PRO Kit & decided THAT was my new RECOMMENDATION for him!!! This will be the easiest question ever for this Forum I suspect... Thank you all in advance for the assistance! PLEASE HELP...
