Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Delta 4 is one hot new regulator ready to take on all challengers with improved performance, new features, improved styling.

2005 ScubaLab Tester's Choice
"Hooked up to the breathing simulator, the Delta 4 delivered Very Good to Excellent performance in all the RMV/depth categories, earning the highest simulator scores of all the regs in it's price group.  In ocean tests, the reg was also a champion, collecting the highest total ergo score in its price group. In particular, divers liked the swivel and the mouthpiece, and felt both the adjustment knob and dive/pre-dive switch were easy to use, even when wearing gloves."
