1What's the difference between recreational and technical diving computers?
Recreational models are simpler, designed for dives under 40 meters with no decompression stops, while technical computers handle deeper dives with mandatory decompression stages and mixed gas blends. Choose recreational if you're learning or doing casual dives; go technical only if you're trained and planning complex profiles.
2Does it matter if I buy a watch-style or console-mounted decompression computer?
Watch-style computers are convenient for casual divers and easier to read at a glance, while console models mount to your regulator and often have larger screens for technical diving. Pick the watch version for simplicity and comfort, or console if you want detailed real-time data and don't mind extra hose routing.
3What battery life should I look for?
Most modern computers last 2-5 years on a single charge or battery, which is fine for regular divers. If you dive frequently (multiple times per week), check if the model uses replaceable batteries or needs professional servicing, as this affects long-term costs.
4Should I spend extra for a computer with air integration?
Air integration wirelessly reads your tank pressure and calculates remaining bottom time automatically, which is genuinely useful during dives. It's worth the extra investment if you dive regularly and want precise air consumption data, but it's not essential for beginners doing shallow recreational dives.
5What safety features are most important to check?
Look for redundant displays, audible and visual alarms for depth and decompression stops, and nitrogen loading algorithms (like RGBM or Bühlmann) that match your diving style. Make sure the model displays your actual decompression obligations clearly, not just warnings, so you're in control.
