XTREME MJ survives Hurricane Irma! Read one customer's experience (September 2017):
"We've owned a Bad Boy (Xtreme) MJ for about 3 years now, and it has been a highly valuable device on board. We've got it installed at the top of the mast, riveted in on the provided L bracket. We are located in St Maarten where we recently took a huge Category 5 direct hit with over 200MPH/360KPH winds. I'm happy to report the Bad Boy, with antenna, is still mounted at the top of the mast. Suffice to say, your product is pretty robust. Thanks again!" - Derek, s/y ARAVILLA

If you can find a better price for a complete system similar to Xtreme, we will better it by 10%!

XTREME MJ (Metal Jacket) - Complete Systems


Product Description

Waterproof Metal Jacket Housing. 100+ Mbits*!

Integral 1-14 mounting adapter as part of the housing!

Bitstorm's BAD BOY Xtreme MJ (Metal Jacket) provides two benefits. While it's fully waterproof (submersible - IP67), its biggest benefit is the metal casing protecting the electronics inside during periods of electrical storm activity. It's a faraday shield blocking both external static and non-static electrical fields.

Xtreme MJ supports the latest Wi-Fi Mode N. That means wireless link speeds in excess of 100 megabits/sec (Mbits)* are now possible! Xtreme N pulls in and locks onto the weakest signals. How do we do this? Just as with our other Xtreme models, by putting the highest power Wi-Fi device available right at and connected directly to the antenna, the antenna cable is eliminated. No cable losses. What this means is that all of the available power (up to 36dBm or 4W EIRP) goes out the antenna for maximum range and best possible reception. And the data goes to your computer via a digital (not analog) outdoor grade shielded cable. And since it's digital, you can locate your Wi-Fi device in the best location up to 300 feet (90 meters) away. Masthead installation with its ideal range and clear line-of-sight is now possible. They put your VHF antenna at the highest place for a reason. The same is true with Wi-Fi. No more compromises!

The biggest problem is often the line of sight that's needed for Wi-Fi. Surroundings that have water, wood and metal all conspire to reduce range. Then there's the miniscule power that laptops put out - you can see the hotspot access point but it can't hear your laptop. Unlike laptops and other mobile devices which put out only 35-50mW, this Bad Boy puts out up to 4W (36dBm) of power to get you connected. And keep you connected!

Compatible with Windows, Mac, Linux... any operating system. Rugged, completely weatherproof and continues operating in extreme temperatures. Select Wi-Fi Access Points through your browser so there's no software to install. Multiple mounting options to choose from. And why not complete your system with an Unleashed rebroadcaster that lets you go completely cable free and use the Wi-Fi already built into your computer.

* Refers to the wireless link speed. The actual speed of the internet connection may be considerably less. While wireless data rates up to 150 Mbits are possible, most hotspots provide a connection to the internet of only a few Mbits.

Note: Xtreme MJ is backward compatible with original Xtreme and Xtreme N and is interchangeable.

  1. trouble shooting

    Posted by jerry Livson on 10th Feb 2016

    I saw the product on my friends boat in Tel-Aviv Israel and it worked just fine and made the marinas wifi signal stronger. However lately there has been problems of receiving internet although the signal is strong. My friend can receive internet via laptop or telephone but not via Bit Storm. Do you have an idea a suggestion to make it work?? (Bitstorm: We require more details in order to assist.)
    2. I am in the process of installing my own system and my question is : I am reluctant to cut the 23 meter cable, while only 15 is needed. If I leave 8 meters in a coil, will the signal be weaker this way using the whole length and not cutting 8 meters off using the junction box?? (Bitstorm: no loss of signal will be experienced as dat is carried via digital as opposed to older analog technology.)
    Please reply asap

  2. exceptionally well engineered and made. customer service was awesome.

    Posted by Captain Dave, s/v Down Home on 8th Jan 2016

    Like most after research we have many choices from which to choose. Not being a techie all of the perameters were confusing. In the end I relied in personal recomendations and I have not been disapointed.

    The unit performs better than expected and I dont even have it positioned up the mast yet. It took a few minutes to understand how the software worked but after a short bit of help from Customer Service, I was good to go in no time.

    Thanks Bitstorm.

  3. Quality product

    Posted by Moray on 5th Oct 2015

    well built system, clear instructions. Will have to wait till we are on our travels to se how well it performs out away from our Marina WiFi which already has a good suignal.

  4. 1month from shipment and I still don't have the product

    Posted by Chris on 27th Jun 2015

    I contacted Canada Post, Spanish post office (for delivery) and Bitstorm and nobody does anything about delivering this package to me. Bitstorm should care more and step up to solve this issue. I guess they got the money and they don't care...terrible!

    Bitstorm responds: Your order address was only partially complete and included a partial phone number that was from Canada. In addition, while everyone in North America knows that the country code is +1, Spanish officials have no way of knowing what your incomplete phone number represented and this made it impossible for them to contact you. Lastly, we contacted the carrier and put a trace on it immediately after you contacted us. As we do not own any delivery service, we are unable to demand they do anything. Your order was in customs who were seeking import duties. Bottom line: when providing international addressing for a shipment, complete information needs to be included including both address, contact info and phone numbers. Incomplete information always results in a 'return to sender'.

  5. Works as advertised

    Posted by Rick Johnson on 17th Mar 2015

    I sold my boat with my Bad Boy and have gone the RV route. I have not yet tested the new MJ version, but I was well pleased with the prior version. Used it for 4 years and never a problem. I once picked up over 200 signals while about 1 mile from a condo building. I love the Unleashed product. We have several devices that connect to the internet and this makes it easy, especially the printer.
