Mid-2017 New Release Mares Puck Pro Plus

It’s great to see the entry level dive computers attempting to move towards modern wireless connectivity!

In June 2017 Mares released the Puck Pro PLUS. The Plus has seen more upgrades with regards to the connectivity and adaptability. 

The Mares Puck Pro PLUS comes with a form of Bluetooth which Mares is calling BLUE LINK. It is a Bluetooth clip connector that lets you download dive data directly to your smartphone, without the use of cables and connectors. However this is a separate purchase as it doesn't come with the dive computer and won't be released until 2018.

We're trying to find more specific information on how the Bluetooth chip works. 

What's Different between the Mares Puck Pro and the Puck Pro Plus?

Aside from the touted wireless Bluetooth capability, there are only cosmetic differences between these two models.

The Mares Puck Pro comes in a range of colors available. The Mares Puck Pro + is currently available to buy online in Black or White. There is a Grey option but this is yet to become available to purchase online.

All of the functions of the two models are exactly the same.

If you already have a Puck Pro and want to buy the USB cable to download your diving logs, the software is free to download from the Mares website. Another great open-source option worth looking at is Subsurface. The download cable also allows for firmware updates to the Puck Pro that Mares release from time to time. 

Mares Puck Pro versus Mares Puck Pro Plus with Bluetooth

How does the Mares Puck Pro compare with similar Dive Computers?

When it comes to entry-level dive computers there are 3 models that are usually mentioned in the same breath. These are the Mares Puck Pro, the Suunto Zoop and Cressi's Leonardo.

This is because these are very similar when it comes to both functionality, price, and reliability. All three dive computers are high quality with only slight differences between them.

Most entry-level diving computers in this price range do NOT include the USB cable needed to download dive information. This is an optional accessory and is not included in the purchase price of the Leonardo, the Zoop or the Puck Pro dive computers.

Mares Puck Pro Plus versus Suunto Zoop Novo

In January 2017, Suunto discontinued the Zoop. These are currently still available for sale so you might find some bargains. The Suunto Zoop Novo is more expensive than the Zoop, (as well as the Puck Pro and Leonardo), but it has more features as well. If you have a little more to spend then take a look at the Zoop Novo Comparison and review.

You really need to work out what features you want, and just go for it. Entry-level dive computers are always in demand and generally hold their resale value well. They'll also serve you well as a backup dive computer if you decide to extend your training later on.

Is the Mares Puck Pro Plus really the size of a hockey puck?

The Mares Puck Pro Plus is a big dive computer. The case is 2 ⅓ inches (or 60 mm) in diameter by 1 inch thick (25 mm). You won’t get away with wearing this as an everyday watch as it really is almost the size of a hockey puck.

Its overall size makes it very easy to read underwater. It has a segment display which has a backlight and the display is mineral glass crystal.

It's a good-looking and durable design. The Puck Pro Plus looks a little more stylish than its predecessor. Both have a black rubber watch-style strap that is long enough to go over your wetsuit or dry-suit.

How easy is it to navigate a One Button Menu?

The Puck Pro Plus has a one-button style menu operation. The menus are easy to navigate. Press the button to scroll through the menus, then hold the button to make adjustments to the menu you're in.

This single button menu operation is a nice touch, which is easy to press even with gloves on.

Mares Puck Pro and Puck Pro Plus - Functions and Features

When in Surface mode you can change settings, use the dive planner, see remaining saturation after a dive, review your logbook and download to a PC or Mac. The dive settings can't be changed once you're underwater.

During the Dive mode, the Puck Pro Plus monitors the depth, time, temperature and performs the decompression calculations. Although it monitors your depth, the Puck Pro does not have a Depth alarm. This may be important to know for anyone who has restrictions on their diving depth due to medical or other reasons.

The backlight can be adjusted to display between 1 to 10 seconds before fading, to help conserve battery life. It can also be set to ON so it remains on until you press and hold the button again.

The Puck Pro and Puck Pro Plus has a Rapid Ascent alarm (based on 30 feet per minute), and it alerts you if you miss a decompression stop.

Pre-dive, Surface Interval & No Fly Time

The Puck Pro and Plus always switches on in pre-dive mode. This mode puts the dive computer in a ready-to-dive mode. It checks the ambient pressure during pre-dive.

It won't begin to calculate a dive until submerged below 4 feet (1.2 meters). Once submerged, pressing the menu button will activate the backlight and light up the display.

After surfacing both the Puck Pro and Puck Pro Plus dive calculations are paused. This resumes if you re-submerge within 3 minutes and it logs the time on the surface as part of the dive. Once past 3 minutes on the surface, the Puck Pro closes the Logbook for that dive.

The display then shows desaturation time, no-fly time and the surface interval. It will continue to show the desaturation and no-fly time until both are reduced to zero. If you're diving in lakes above sea level, the Puck Pro comes with an adjustable Altitude setting to 3,700 feet.

Does it come with Imperial or Metric settings?

The Puck Pro Plus lets you switch between imperial or metric depending on your personal preference (meters and Cº, or feet and Fº). It can be set in either show either 12 hour or 24 hour format.

What about the Dive Planner and Logbook Memory?

The Puck Pro PLus has a great Dive Planner. When entering your intended dive depth, it calculates how long you can stay at that depth. This is based on your last dive, surface interval and desaturation time.

The algorithm adjusts the no-decompression time by assuming you've spent the entire time of previous dives at the AVERAGE depth.

The Log holds around 35 hours worth of dive time, sampling at a rate of 5 seconds. You can't delete old dive data, you have to wait until it deletes itself out. You'll need to transfer this to a Dive Log to keep the information.

What's the expected Battery life and is it User-Changeable?

On their website, Mares state that the battery of the Puck Pro and Puck Pro Plus is user-changeable.

On both dive computers, the battery compartment is sealed off from the other part of the computer. This means it won't flood the rest of the computer if this isn't sealed correctly.

The battery is a standard 3 volt CR2450 on both models.

The battery life is estimated to be somewhere between 300 to 500 dives. This varies depending on how you use it. Diving in cold water, use of the backlight and the beeper will increase the battery consumption.

The battery icon doesn't show while it has plenty of charge. The icon will appear as a steady symbol as the battery starts to run low. There will still be enough charge for a few more dives, but you'll need to consider changing the battery shortly after the symbol appears. The backlight function will stop working once a low battery warning is activated.

The battery icon blinks when there's not enough battery for diving. Once the icon starts blinking, the Puck Pro doesn't function very well and won't turn on underwater when the battery symbol is blinking.

The Battery Kit comes with a new battery door, a new o-ring seal, and a CR-2450 3v battery.

The video below shows how easy it is to change the battery on the Mares Puck Pro.

Which Algorithm does the Mares Puck Pro use?

The Mares Puck Pro and Puck Pro Plus use the RGBM (Reduced Gradient Bubble Model) algorithm.

This algorithm is considered a more conservative algorithm and is great for beginner and recreational divers. Later on if you want to expand on your training and move into more technical diving, then you'll need to explore dive computers with different algorithms.

The Puck Pro Plus has a Precautionary Program setting which allows for adjustment to more conservative profile settings. This is good if diving at different depths over multiple days.

Which functions is the Mares Puck Pro Plus missing?

The Mares Puck Pro Plus is marketed as an entry-level dive computer, so it has all the functions beginner divers or recreational divers need. It doesn't have a Depth alarm which you may need be aware of for medical reasons.

The Puck Pro Plus doesn't have wireless Air Integration. If you're after wireless air integration, have a look at some of our other reviews on mid-level diving computers. Don't forget though, more advanced features will add to the cost of a dive computer. The Puck Pro and Puck Pro Plus is an entry level, affordable dive computer.

The Puck Pro Plus doesn’t have a digital compass, tri-mix or a Depth alarm. If you’re after these features, then have a look at the Suunto Vyper Novo, Suunto D4i Novo or D6i Novo, or the Shearwater Perdix AI.

If the Puck Pro Plus remains in a pre-dive mode for longer than 10 minutes without the button being pressed, the computer switches itself off.

You need to make sure the Puck Pro Plus is switched into pre-dive mode before submerging. If you start a dive without doing this, the Puck Pro Plus will still start to monitor the dive automatically, but with a delay of up to 20 seconds after submerging.

What about the Warranty and Puck Pro accessory prices?

The Mares Puck Pro is very nicely priced for an entry-level dive computer. This comes with a 2 year Manufacturer’s warranty.

The USB cable accessory needed to download the dive data from the Mares Puck Pro to your laptop is an optional extra which will is rapidly dropping in price thanks to the release of the bluetooth capable Puck Pro PLUS. The cable currently costs around $50. The software is free to download directly from the Mares website. However it is a separate purchase as it doesn't come with the dive computer.

The Mares Replacement Battery Kit will cost around $15 and includes the battery, o-ring, and a fresh battery case.

What about Maintenance and Care?

When it comes to getting the best performance and longevity out of your equipment, always thoroughly rinse the computer in fresh water after each dive. Dry off and store in a cool, well-ventilated place away from the damp.

The condition of the band, clasp and metal components need to be regularly checked. Over time these can become affected by a build-up of sunscreen, perspiration, and sea-salt.

For peace of mind and to avoid problems or disappointment before a dive trip, have the dive computer serviced every 2 years. The computer functions, the waterproof seal, and calibration should all be checked.

Our Conclusion?

The Mares Puck Pro PLUS has the functionality beginners and recreational divers need. The one-press menu button and menu navigation make it a great entry level dive computer.

If you've been looking for a new scuba computer and have your eye on the Puck Pro then there are some really good deals to be found online at the moment.  

Work out which features you really want from your dive computer, then go for it!

I really like the size of the Mares Puck Pro. Am I right in guessing it is between the size of the Cressi and the Zoop?

Carl Reply

Hi , thanks for the review. i am new to diving, so i really like the function of the dive planner and logbook memory. to be able to have all the details worked out for me while i am on my dive is great. the price is good too, as i am trying to buy the rest of my gear.

The Mares Puck Pro is a pretty interesting piece of technology. Amazing how far things have come to help keep diving safe. Thanks for all the great info. The comparison chart helps work out which DC will work best for me.

I like that it can do both metric and imperial, but it would be a great idea to include a depth alarm as well. The colors are good too.

Hi Sharon,

Wow, dive computers. I am no diver or tech guy, but the technology I see here is amazing. Inspired stuff.

I recall living on Koh Lanta in Thailand for a month – big dive spot – and our neighbor who was an instructor wanted to get us in the tank. Next time, I am in.

Thanks for sharing.

    Hey Ryan, a month on Koh Lanta sounds fantastic! Let us know how you go when you decide to take the plunge and give diving a go. I’d love to hear about it. Cheers.

Hi Sharon,

Because of the Bluetooth confusion with the Puck Pro +, I contacted Mares support, and got this response back.

“Sorry for any confusion! The Puck Pro + can transmit logbook information via a Bluetooth clip called ‘Blue Link’, sold separately. This clip will be available in 2018.
Best regards, The Mares Team”

BTW, thanks for the brilliant review. I decided to go ahead with my purchase, as the USB connection does everything I need anyway.

    Hi Trevor,

    Thanks for sharing! It feels like Mares are teasing us with this.

    I’d been trying to find more information about the Bluetooth connection and how it works without much luck. I’ll update the review and keep an eye out for when the Blue Link clip comes out for sale.

    Appreciate the info.


Trevor Wilson Reply

Hi again Sharon, just to bring you up to date with what I now know.

Firstly, thank you very much for personally putting in the time to help me solve this riddle.

After more exchanges with Mares Support, I was able to gather up much more information about “Blue Link”.

“Blue Link, available from 2018, sold separately” has now been added to the text on the Mares News page on the Puck Pro + page.

The Bluelink connector, which is sold separately, replaces the old USB connector. It operates the same as every other blue tooth device and is approximately the same size as the current USB connector, and will retail at around the same price. It will be available for the Puck Pro, Puck Pro + and Quad computers.

It has driver software for both Macs and PCs.

So the main difference is the fact that the existing device has a USB cable, and this new one is paired via Bluetooth and doesn’t need a cable. I went for the USB cable version as it is available now, and works just fine.

One source told me that the “Blue Link” connector is available now, but I couldn’t find it on the Mares site, or anywhere else that I searched.
