Pros
  • Crisp color OLED screen, easy to read underwater
  • 3-axis digital compass built in
  • Paired-for-life wireless transmitter option for hoseless air integration
Cons
  • Appears to be discontinued/replaced by the i770R in Aqualung's current lineup
  • User-replaceable battery is less convenient than one battery type across the line
  • Retail pricing is inconsistent across sellers, suggesting closeout stock

The i750TC was Aqualung’s color-screen, air-integrated computer before the i770R replaced it. It’s still findable through some retailers, but Aqualung’s current site steers new buyers toward the i770R instead, so treat this one as legacy/closeout stock rather than a current product.
