I recently had a former student contact me who I assisted with during her o/w class. She just discovered HP steel 80 tanks and has to have them! I told her no problem- just buy a DIN conversion for your reg (a Tusa) and take it to your LDS to be installed. She wanted to know a price, so I told her to check L-Pro and S-Toys. To my surprise neither site listed a DIN conversion for Tusa regs!! When I typed Tusa DIN conversion in google, I couldn't find one either. Help me out here guys my rep as a Divemaster extroridaire is on the line here!!
