The Scubapro Galileo family has long been the stalwart of the company’s computer range, and the Luna represents the entrylevel to this line-up. The huge dot matrix display has three visibility settings - with the largest being particularly useful for those with failing eyesight! - and the three buttons make for effortless navigation. It has a user-replaceable battery, a clear and concise digital compass, and out of the box can link to a single transmitter for total air integration. The chunky strap can easily go around a drysuited arm, and the bright backlight aids visibility in low light conditions. It comes without the heart-rate monitor of the higher-level Sol, but can be upgraded at a later date.
