What the Mares Puck Pro Is Designed For
The Puck Pro is built for recreational diving only. It is not intended for technical, cave, or expedition diving, and it does not attempt to support complex gas switching or decompression planning.
Instead, it prioritizes:
- Simplicity over configurability
- Affordability over premium materials
- Clarity over advanced graphics

Ease of Use and Learning Curve
The Mares Puck Pro is arguably one of the easiest dive computers to learn.
It uses a single-button interface, meaning all menu navigation, confirmation, and scrolling are handled with one physical control. This reduces confusion for beginners and eliminates the need to memorize multiple button combinations.
The trade-off is slower navigation. Moving through menus requires sequential button presses rather than quick jumps, but for most recreational divers, this is a small price to pay for simplicity.
The Puck Pro activates automatically when submerged and requires minimal setup before diving. Nitrox settings can be adjusted easily, and the main dive screen displays only essential information, reducing clutter.
Design and Physical Feel
The Puck Pro has a round, puck-shaped housing — hence the name — with a relatively thick profile. It does not aim for a sleek or watch-like aesthetic. Instead, it feels solid and utilitarian.
It is lightweight, comfortable to wear over a wetsuit, and secure on the wrist. The strap is long enough for thick exposure suits, though it may need trimming for smaller wrists.
The display is not large by modern standards, but it is clear, high-contrast, and readable in typical recreational conditions.
Display and Readability Underwater
The Mares Puck Pro uses a monochrome LCD display with high contrast and simple layout. While it does not offer a color screen or advanced graphics, it performs well in the conditions most recreational divers encounter.
Key readability points:
- Large numeric depth and time fields are easy to read at a glance.
- High contrast makes the screen legible in both bright tropical water and darker low-visibility conditions.
- The backlight is functional for night dives and wreck dives, although not as bright as premium models.
Because the display is intentionally simple, it avoids clutter and keeps only essential information visible. This reduces cognitive load, especially for new divers who may already be managing buoyancy, awareness, and situational stress.
Algorithm Behavior and Dive Profile Handling
The Puck Pro uses the Bühlmann ZH-L16C decompression algorithm with dual gradient factors. This algorithm is widely respected and used in many advanced dive computers, but Mares implements it conservatively for recreational use.
In practice, this means:
- Reasonable no-decompression limits without being overly aggressive
- Predictable behavior across repetitive dives
- Conservative ascent warnings that encourage slow, controlled ascents
One commonly noted behavior is that the ascent rate alarm is quite sensitive. While this can be annoying for experienced divers, it is generally beneficial for beginners who may otherwise ascend too quickly.
This algorithm choice places the Puck Pro between highly conservative beginner models and more customizable advanced computers — offering a good balance for recreational divers who want safety without excessive restriction.
Physical Build and Wear Comfort
The Puck Pro’s housing is round and relatively thick, giving it a sturdy, utilitarian feel. It does not aim for a sleek or watch-like aesthetic, but it feels solid and secure on the wrist.
Comfort considerations:
- Lightweight enough to forget about underwater
- Secure strap suitable for wetsuits and drysuits
- Slightly bulky for small wrists, but not uncomfortable
The single-button design reduces the number of mechanical entry points for water, contributing to long-term durability.
Battery and Charging Experience
Unlike many budget dive computers that use replaceable coin cells, the Puck Pro uses a proprietary rechargeable battery.
- Typical life: ~100 dives per charge
- Charging via USB cable
- No need to open the housing for battery replacement
This is convenient for many users, but it also means:
- You cannot replace the battery yourself when it degrades
- Long-term battery replacement may require service or replacement of the unit
For most recreational divers, this is not a short-term concern, but it is something to be aware of for long-term ownership.
Logging and Bluetooth Connectivity
One of the Puck Pro’s strongest features is built-in Bluetooth connectivity.
- Wireless dive log transfer to smartphone or tablet
- No need for proprietary cables
- Compatible with Mares’ mobile apps
This makes it much more convenient than older entry-level computers for divers who want to keep digital records of their dives.
However, the logging software itself is basic and focused primarily on storage rather than deep analytics.
Limitations and Trade-offs
The Puck Pro deliberately omits several features:
- No air integration
- No digital compass
- No multiple gas switching
- No trimix or technical support
- No firmware upgrades
These omissions keep the device affordable and simple, but they also limit how far it can grow with you as your diving advances.

Typical Use Scenarios
Beginner and Newly Certified Divers
The Puck Pro is an excellent match for new divers. Its single-button interface, uncluttered display, and conservative ascent behavior help reduce task loading during early dives. Instead of worrying about menu navigation or advanced settings, new divers can focus on buoyancy, awareness, and safe ascent rates.
Casual and Vacation Divers
For divers who only dive a few times per year, the Puck Pro is attractive because it is easy to re-learn. After months between trips, most users can pick it up and feel comfortable within minutes.
Backup Computer for Experienced Divers
Many experienced divers choose the Puck Pro as a backup computer due to its affordability, reliability, and independence from proprietary gas or integration systems.
Cold Water and Glove Use
The single large button can be operated with gloves, but precise menu navigation underwater is slower than with multi-button computers. Still, for core functions, glove use is not a significant problem.
Common Buyer Mistakes
1. Expecting advanced features
The Puck Pro is not a smartwatch, not air-integrated, and not expandable into technical diving. Expecting those features leads to disappointment.
2. Buying it as a “future-proof” platform
If you plan to progress into technical or decompression diving soon, you will outgrow the Puck Pro quickly.
3. Forgetting to consider long-term battery replacement
The rechargeable battery cannot be replaced by the user. This is not a short-term issue, but it affects long-term ownership.
4. Underestimating ascent alarm sensitivity
Some divers find the ascent alarm too sensitive. This can usually be managed with controlled ascent habits, but it is worth noting.
When You Will Outgrow the Puck Pro
You will likely outgrow the Puck Pro if:
- You want air integration for tank pressure

Long-Term Ownership and Reliability
One of the Mares Puck Pro’s biggest strengths is that it is designed to be a low-maintenance, dependable recreational dive computer.
The sealed housing and rechargeable battery mean there is no need to open the unit for routine battery changes, which reduces the risk of flooding due to improper sealing. This also makes it attractive for rental fleets and training environments, where simplicity and durability matter more than customization.
With proper care — rinsing after dives, charging before trips, and storing it in a cool, dry place — the Puck Pro typically performs reliably for many years. Reports of electronic failure are uncommon, and the simplified design limits points of failure.
The primary long-term consideration is the rechargeable battery itself. Over time, all rechargeable batteries degrade. While this is not a concern in the first several years, very long-term ownership (5–7+ years) may eventually require service or replacement.
