Product Information
The Scubapro Smart+ Pro Transmitter is a hoseless air integration transmitter that screws into a high-pressure port on your regulator's first stage and relays tank pressure and true remaining bottom time (RBT) straight to a compatible Scubapro dive computer. It uses coded transmission technology so nearby computers do not interfere with each other, and it runs on a user-replaceable CR-2PE/BN lithium battery rated for 3 years or 250 to 300 hours of diving, whichever comes first.
Who it is for
This transmitter is for divers who already own, or are buying, a Scubapro HUD, G3, G2, G2 Tek, A2 or Luna 2.0 AI and want tank pressure shown on their dive computer instead of a hose-mounted pressure gauge. Because it removes the high-pressure hose from the setup, it suits divers chasing a streamlined, snag-free rig, and the RBT readout is useful on multi-level and deeper recreational dives where remaining gas and no-decompression time both matter.
Key details
- Pairing: required only once, during initial use.
- Coded transmission: prevents interference between different dive computers in the water.
- Compact body: improves first stage mounting options.
- LED status light on the cap: 1450 PSI and over = slow short blinking green; between 1450 PSI and 725 PSI = short double blinking yellow; below 725 PSI = long single red blink.
- Gas check without the computer: the built-in LED estimates tank pressure once the first stage is attached to a tank.
- Battery: user-replaceable CR-2PE/BN lithium cell.
Compatibility and sizing
Compatible with Scubapro HUD, G3, G2, G2 Tek, A2 and Luna 2.0 AI dive computers. It threads into a high-pressure port on a dive regulator first stage. Item number 05.055.040.

- Hoseless air integration threads into a high-pressure port on the regulator first stage and sends tank pressure to your dive computer, so no high-pressure hose is needed.
- True remaining bottom time transmits RBT along with tank pressure to the computer display.
- One-time pairing is required only once, during initial use.
- Coded transmission technology prevents interference between different dive computers.
- Compact size improves first stage mounting options.
- LED status light on the cap shows slow short blinking green at 1450 PSI and over, short double blinking yellow between 1450 PSI and 725 PSI, and a long single red blink below 725 PSI.
- Pre-dive gas check uses the built-in LED to estimate tank pressure once the first stage is attached to a tank, without activating the computer.
- User-replaceable battery uses a CR-2PE/BN lithium cell.
- Battery life rated at 3 years or 250 to 300 hours of diving, whichever comes first.
- Scubapro computer compatibility covers HUD, G3, G2, G2 Tek, A2 and Luna 2.0 AI.

Frequently Asked Questions
Which dive computers work with the Scubapro Smart+ Pro Transmitter?
Scubapro lists the Smart+ Pro Transmitter as compatible with the HUD, G3, G2, G2 Tek, A2 and Luna 2.0 AI dive computers. Pairing is needed only once, the first time you use it, and the coded transmission keeps your signal separate from other divers' computers nearby. If you are unsure about your specific computer or firmware, call us at 888-701-4017.
What battery does the Smart+ Pro Transmitter use and how long does it last?
It uses a CR-2PE/BN lithium battery that the user can replace. Scubapro rates the battery for 3 years or 250 to 300 hours of diving, whichever comes first, so calendar age matters as much as dive time. Plan on a fresh cell before a big trip if either limit is close.
How do I read the LED light on the transmitter cap?
The LED on the cap gives a quick pressure estimate once the first stage is attached to a tank, so you can confirm you have gas without turning on your computer. At 1450 PSI and over it shows a slow short blinking green light. Between 1450 PSI and 725 PSI it blinks short double yellow. Below 725 PSI it gives a long single red blink.
Does the Smart+ Pro Transmitter replace my submersible pressure gauge hose?
Yes, that is the point of it. The transmitter screws directly into a high-pressure port on your regulator first stage and sends tank pressure and true remaining bottom time to your dive computer, so no high-pressure hose or analog gauge console is required. Its compact body also gives you more flexibility in how you position it on the first stage.
Review summary
Reviewers consistently describe this transmitter as easy to set up and pair, and they value seeing tank pressure on the dive computer during a dive. Several note it mounts easily with room on the first stage, and one was glad to keep two computers on separate signals. One longtime user calls the transmitters about as reliable as a mechanical gauge, with occasional brief dropouts lasting a few seconds. The same reviewer found the status LEDs unhelpful, since green shows until the tank is half empty. A good fit for divers adding air integration to a compatible Scubapro computer.
