What’s so special about a Piranha Underwater Scooter?

  • It’s incredibly Lightweight. The Piranha dive scooter with one battery is only 24lbs.
  • Travel friendly, by using small power tool batteries that combine in the scooter to create one big battery, you can FLY on a commercial airline with your Piranha underwater scooter.
  • Its Modular, you can add batteries to suit the length of dive you want to do.
  • It uses Power tool batteries you can find in almost any country in the world, they are readily available, low cost and easy to replace.
  • It has more Power than you probably need. Take a look at all the scooters out there, even from our competitors like Suex, Silent Submersion or Bonex. The Piranha underwater scooter has 326N of thrust, in the same league as all the big scooters, but its only 24lbs… and you can travel with it.
  • Neutrally buoyant and trim. Meaning it doesn’t float or sink, just hangs in the water level and flat.

P1, P2, or P3??? What does it mean?

P1, P2 and P3 refers to how many battery modules your scooter comes with from the factory. Each battery module gives you proportionally more range and runtime.

The Piranha underwater scooter only needs one battery module to work, and with over an hour of runtime in normal use, the one battery dive scooter (we call it a P1) it is our most popular diver propulsion vehicle.

But many divers need more range or runtime to suit the type of diving they do, and so to accommodate that, you can purchase additional battery modules which simply stack together to create the underwater scooter with the range and runtime you need.  So, if you typically need over 2 hours of runtime, you could purchase a P2, with two batteries.  If you typically need over 3 hours of runtime, you could purchase a P3, with three batteries.

Remember though that the Piranha dive scooter only needs one battery, so if you have a P3 for cave diving, but this weekend you are only recreational diving with your friends, just use one battery and enjoy a lighter more maneuverable scooter.

Power Tool Batteries?

All Dive Xtras Piranha underwater scooters now run on power tool batteries. We have stopped designing our own custom batteries and started using readily available batteries that you can buy worldwide.  In each battery module on a Piranha DPV you click in four 20v 5Ah 100 Wh power tool batteries to create a larger 40v 10Ah 400wh battery. To charge them you simply unclick them and charge in their original charger.  Why did we do this? For many reasons:  

  • They are readily available, you can buy them worldwide along with chargers.
  • They are air travel compatible. You can fly with them.
  • Charge time is only 45min
  • They can be combined to make a larger capacity battery in about the same size and weight as a custom designed battery, so you don’t sacrifice size and weight.
  • You can ship them without difficult hazmat issues. (Did you know that if you buy a scooter with a big Lithium battery, it’s extremely difficult for you to ship it back to the supplier legally)
  • They are very high quality and low cost. Power tool company’s are a lot larger than dive companies, the effort they put into designing a battery is far greater than a dive company ever could, and also they make millions of batteries, we can take advantage of their economies of scale.

Pro package? What is this?

The pro package is a Piranha underwater scooter bundled with the most useful accessories a serious diver would want. So, if you’re looking to buy the best, get the pro package.

The biggest accessory is the smart slice. This module combines a lot of great features in a single module that drops straight into the Piranha stack. You get:

  • Fuel Gauge, how much battery have you used on the dive. The smart slice has an LED display that shows you your battery usage during the dive.
  • Vacuum Leak Detection, check your scooter is all sealed up before you dive. The smart slice has a vacuum port and a pump that allows you to pump a vacuum on the scooter before the dive. An internal sensor then checks for any leaks.
  • 12v Power Outlet, suit heater? Video lights? The smart slice has an underwater connector that allows you to connect any accessory that runs on 12v.
  • Emergency Cutoff.  Concerned about a runaway scooter, pull the cord and your scooter shuts down.  It’s extremely rare, but for people who worry, it’s a little bit more reassurance.

The other key accessory is the Gauge mount. It attaches to the handle and provides all the primary information needed for dive navigation right at your fingertips. The standard gauge mount includes a Suunto SK8 compass and analogue depth gauge.

My Piranha doesn’t come with the PTB modules what do I do?

All Dive Xtras Piranha underwater vehicles ship from the factory without batteries or chargers. This is because they use commonly available power tool battery modules, and its easier, and cheaper for you to source them locally.  Here in Seattle we mostly buy them from Amazon, or a local hardware store such as Home Depot. There are some specifics on the type and size, which you will learn about if you purchase a scooter, buts it’s very simple and if you need help, we are happy to do so.

I’m just a recreational diver, which one should I buy?

The BlackTip is our newest scooter model, designed with both recreational and professional divers in mind. It’s all-in-one design and lightweight travel-ready size make it a great scooter for most needs! It’s priced similarly to other recreational scooters, but retains many impressive performance features typical in Dive Xtras’ professional-grade scooter models.

Alternatively, you can buy a P1 pro package. This gets you the basic scooter, the smart slice for fuel gauge and leak detection and the gauge mount.

If you are worried that you may progress and need more range and runtime as your diving progresses, don’t. You can always add an extra battery later.

If you are doing multiple dives a day, purchase more than one set of PTB modules. They charge In 45 min so you can charge one set whilst you dive with another, and swap during the surface interval.

I’m just starting in tech or cave diving, which one should I buy?

You should buy a P1 pro package, and then add batteries as your diving progresses.  The pro package gets you the basic scooter, the smart slice for fuel gauge and leak detection and the gauge mount.

When you get to the point that your diving is exceeding the range and runtime of a single battery, purchase an additional battery module (or two) to double or triple your range and runtime.

I’m a cave diver, which one should I buy?

You should look at the range and runtimes required for diving you are doing, and would like to do, making sure you include the appropriate safety calculations like the rule of thirds and required redundancy.  Then compare that with the performance figures for the P1, P2 and P3 scooters and make your selection.

Note: its hard to make the wrong choice with a Piranha as it is a modular scooter and so there is no negative to adding batteries at a later date.

Can I use more than three batteries?

The piranha will work with as many battery modules as you can connect, at some point it becomes physically difficult to handle, but it will function.

I want to travel with my scooter, which one should I buy.

The Piranha underwater scooter is air travel friendly as each of the power tool battery modules are small enough that they are allowed on passenger airlines. You need to carry each of the power tool battery modules as carry-on luggage, but the main scooter can go your main luggage. Four PTB modules weigh 5.5lbs or 2.5kg and without the PTB modules a P1 weights 19lbs or 8.5kg

I want to do 4 dives a day with my scooter, which one should I buy?

The answer to this question depends on the topside environment when you are diving.

If you are on a liveaboard or other location with dry space and power:

With a P1 underwater scooter you can dive continuously with 8 PTB modules. 4 in the scooter and 4 charging whilst you dive. When you take your surface interval simply swap the PTB modules and as they charge in 45 min they will be fully charged before you end the next dive.

If you really want to you can also dive continuously with 6 PTB modules. 4 in the scooter for the dive, and 2 charging.  During the surface interval charge 2 of the ones you just used giving you a total of 4 charged PTB modules at the end of the surface interval.  During the next dive you charge the remaining 2 modules and repeat.

If you are on a small wet boat or other remote location with no access to dry space and power:

Take additional fully charged PTB modules with you and swap them, or if it’s really wet and you don’t want to risk opening the scooter the only option is to buy a scooter with enough battery capacity (P1, P2,P3) to do all your days diving so you don’t have to open the scooter
