Replaced My 4 Year Old 550i

By on February 09, 2026 Verified Buyer

My 2022 sensor depth reading on my aqua lung integrated i550 computer malfunctioned which is not repairable and aqualung offered no assistance or credit. They don’t keep stats on product life expectancy. It’s an expensive piece of equipment and I’ll be looking to switch from aqua lung when this one breaks.

Thank you for your valuable feedback about this product.
