The spacious interior comfortably fits handguns, valuables, or important documents, making it a perfect fit for home, office, or bedside use. Designed for safety, built for trust.

Features

FBI Tested and Certified Fingerprint Sensor
The heart of any biometric safe is its fingerprint sensor. That’s why we’ve designed Verifi Smart Safes with the best, most reliable sensor for quick access you can depend on. Safes built with small, cheap optical sensors often include keypads for backup access when the sensors won’t work. That’s not how we build Verifi Smart Safes. All Verifi Smart Safes are engineered with the TouchChip® large area, capacitive fingerprint sensor.

The superior TouchChip® fingerprint sensor has been tested and certified by the FBI to meet the Next Generation Identification (NGI) standard for fingerprint image quality. It’s large because it must be. A smaller sensor wouldn’t provide the quality fingerprint images needed to properly secure your firearms, prescription medications or other valuable items.

Larger and sharper FBI certified fingerprint image

 

The TouchChip® sensor reads fingerprints at a high resolution of 508 dpi. This helps to capture more of the minute details in a fingerprint and enhances the performance of the recognition system.

Why use an active capacitive sensor?

*3D Superiority
3D capacitive sensors work below the surface of the skin to give the best fingerprint image, even when reading worn, dirty or delicate fingerprints.

*Liveness Detection
Unlike optical sensors that can be fooled by a photocopy of an original fingerprint, anti-spoof capacitive sensors interact with living tissue to detect the features of a fingerprint.

Capacitive fingerprint sensor technology

 

Self-Diagnostics
Once every 24 hours and after every use, Verifi Smart Safes perform thorough self-diagnostic tests on their electronics and batteries to ensure they’re ready for use. If a Verifi Smart Safe detects a problem, it will grab the user’s attention with audible and visual alerts.

Some of the questions our Smart Safes ask themselves:
*Battery Health- Do my batteries have enough power to fully operate me in an emergency? How much battery life is left?

*Fingerprint Sensor- Are there any problems with my sensor that would prevent the user from quickly opening me with an enrolled fingerprint?

*Locking Mechanisms- Is there an issue with an internal component that would prevent me from locking or unlocking?

Battery Life
Enjoy years of worry-free operation on a single set of AA batteries* with picoPower and Boost technologies.
  *Compatible with standard alkaline batteries (included) for up to 4 years of battery life.

picoPower CPU
Our picoPower CPU is designed from the ground up for extraordinarily low power consumption while maintaining cutting edge performance.

Boost Performance
Boost power technology ensures LCD brightness and motor speed remain constant even when the batteries are nearly depleted.

Automatic Battery Health Monitoring
Every day, even if you don’t use your Smart Safe, a diagnostic test is performed to determine the health of your batteries.

Verifi Smart Safes know the difference between batteries that are only marginally low and can be changed at your convenience versus batteries that need immediate attention because they’re nearly depleted.

If needed, your Smart Safe will set a low battery alert prompting you to change batteries. This alert can be snoozed for up to three days so you don’t have to worry about it keeping you up at night.

Battery Meter
A battery meter can also be accessed via the settings menu to view percentage of battery life remaining and actual measured voltage.

 

Alerts
Alerts keep you informed and in charge.

Open Door Alert
Leaving your safe’s door open could have disastrous consequences, especially if a firearm is stored inside and made easily accessible to a child. Our Verifi Smart Safe has you covered. Sensors in the door detect if it remains open and will trigger an audible alert in such an event.

Tamper Alerts
House guests, kids or even maids may be interested in trying their fingerprint on your Verifi Smart Safe. Any such attempt triggers a tamper alert so you’re kept informed of what happens when you’re not around.

Backup Key Access Alert
Backup keys are included for access through a key slot hidden behind the logo plate. If a key is used, your Verifi Smart Safe logs an alert so you’ll know when it happened.

 

Reset Attempt Alert
Many safes are vulnerable to a “reset attack.” This is when someone presses an internal reset button from the outside of the safe. Verifi Smart Safes reject these attacks and can only be reset with a fingerprint from a registered admin.

 

Automatic Locking Door
How can you be sure your Verifi Smart Safe is locked? Just close the door. With AutoLock, if the door is closed, it’s locked. It’s as simple as that.

Adjustable Lighting with Nite-Lite+
Engineering interior lighting that won't drain your batteries is not an easy feat- but we've done it! Verifi Smart Safes feature an LED lighting system that can be varied in intensity and duration without significantly impacting battery life.

When set to Nite-Lite+ intensity, the LED will provide just enough soft, indirect light to illuminate your safe’s contents without causing night blindness, which can be dangerous in a middle-of-the-night emergency. But if you find yourself needing more light, just hold the start button on the front of the safe and release it when it has reach your desired intensity.

Easy User Management
You can easily add/remove users, customize user names, change lighting settings, view access logs, check your battery level, and more from the convenience of your Verifi Smart Safe’s LCD screen.

Carpeted Interior
The interior of the Verifi Smart Smart is lined with soft, black carpeting to protect valuables from scratches, and to reduce noise produced by items coming into contact with the body of the safe.

Access & Event Logs
Access logs show which users opened/closed the safe and when. Event logs show previous alerts, alarms, diagnostic results, etc. The last 1,000 logs of each type (access or event) are stored and viewable only by a registered admin.

Solid Steel Construction
Concealed hinges and a recessed door help protect against pry-attacks. Pre-drilled holes located at the bottom for easy mounting to prevent unauthorized removal. (Mounting hardware included.)

FSD Approved
Need a gun safe to properly secure your firearm? All Verifi Smart Safes are listed on the California Department of Justice Roster of Approved Firearm Safety Devices.

Engineered in the USA
Zvetco Biometrics is an American engineering company based in Orlando, Florida. Verifi biometric products are used by hundreds of corporations, banks and government institutions across the USA.

Great company

The customer service was great. Thank you, Shellah! Love the safe. My only suggestion is that you include a bolt for securing it to the floor.

Great safe and very well made.

Great safe, very well-made. Nice finish and details. Very heavy, exactly what I wanted. Easy to unlock and lock.Plenty of room inside for my valuables. Great value and great customer service from Mammoth.

Great safe. Very thick heavy duty.

This is a well made safe. The door is very thick and fits on either way when closing it up. The metal is thick and fits nicely in the hole we cut thru the concrete. I completed the install in about 6 hours. If I had a bigger jack hammer it would have been half that.

Still great after a few years

I have had this safe for a couple of years now and couldn't be happier. I get a lot of compliments on the look and everyone is impressed when they get to look inside. This is the perfect safe at the right price. It is better than your average safe from the local sporting good store rating wise, and more importantly is made by a company that won't give up access to your safe upon simple request. Hopefully I will have to buy another safe some day because this one is full, and if I do, it will be a Stealth safe from Mammoth.

Mammoth Safe and Stealth UL50 Review

I was in the market for a large safe and had looked at all the options in the $1500-$3000 range. I was very close to purchasing a Liberty USA 50 safe, or one of its Liberty variants from Tractor Supply, Sportsman’s Warehouse, etc. In fact, I was finishing my research on the Liberty when I discovered the Stealth brand when reading this review; https://www.expertsafereviews.com/liberty-usa-50-gun-safe-review/ In hindsight, that review is one of the most fair and accurate reviews I found on any product, and it also provided comparable alternatives. Kudo to the authors!

I’m usually pretty brand loyal and have owned a Liberty Lincoln safe for 25 years. I would still purchase the USA 50 had I not discovered the Stealth UL50. I researched all the information I could find about the UL50, with a particular focus on customer reviews and photos. I typically find customer photos are often a more accurate depiction of the actual product than marketing photos, which is why I’m also including photos in this review. However, the photos provided by Stealth of the UL50 on their website, and Mammoth’s site, are really spot on.

From a security perspective, I was looking for; thickness of the steel body and the door needed to be at least 12 gauge, the gap between the door and body needed to be minimal, and the doors needed to have a decent number/size of active bolts or bars. Lasty, I really wanted the top and bottom of the doors to have bolts/bars without having to pay over $3k to get them. The Stealth UL50 met or exceeded the Liberty USA 50 in each of these categories.

Although fire ratings are worth comparing, for me the reality is there will always damage to a certain extent, whether the fire is 1200 degrees or 1400 degrees, and I certainly won’t be checking the duration of fire with a stopwatch. Still, the fire rating of the USA 50 and the UL50 are the same.

Once you have compared a lot of safes you know there is a wide range in quality, especially when looking inside. Many appear unfinished, with rough / undressed welds, thin paint or coatings, and poor fitting shelving / interiors. Not so with Stealth, the fit and finish is very good. The reconfigurable Molle door system is also a huge bonus! Because I was looking for a safe to go in my garage, I also wanted a durable/industrial type finish and the Stealth coating is perfect for my needs. Granted, the finish may hide weld dressings and other finish details, but that and the durability is exactly why I like the Stealth coating so much. My Liberty safe is in my office and has a nice gloss finish; however, that is not what I wanted in my garage.

Frankly, I am extremely pleased with my UL50 and have zero regrets for purchasing it. However, there is one minor recommendation for improvement. Although I really like the way the power cable plugs into the safe (similar to a TV, PC, etc.), I recommend moving the cable connection from the right side to the back of the safe. Why? The current placement isn’t very stealth (yes, I did) and I prefer not seeing a cable sticking out from the side of the safe. I understand this was to enable the back of the safe to sit flush with the wall, so moving the cable connection from the center of the fight side to the very rear of the right side would also be a good option. I ended up drilling a hole through the rear wall of the safe for cable entry and then rewired the power outlet. This is a minor issue.

I have added a light kit and a dehumidifier to the safe, and I will add guns once I’m satisfied with the humidity level. Based on initial testing, it appears I will need the larger Peet dehumidifier to maintain relative humidity below 50%.

So what about Mammoth Safes? One-word summary; Wow!

I compared several companies that sell the Stealth safe when I found Mammoth. Mammoth has comparable pricing including shipping to other vendors. However, they have no tax and I also found a coupon, so when combined, Mammoth saved me several hundred dollars over the next closest company. That said; I was somewhat hesitant to order initially from Mammoth because they are a relatively new company without a lot of reviews. Thankfully there was just enough information on the web that I felt fairly confident that the advertisement was not a scam.

I really appreciate Mammoth’s efficient ordering, communication and delivery process….simply impressive! From ordering to delivery, California to South Carolina, in 6 days……impressive! The safe was very well packed, and I received it with no damage. Mammoth has done their customer service homework and it shows. Between Mammoth’s pricing, customer service and Stealth’s product quality…..I have and will continue to highly recommend both companies to anyone needing a safe!!! Well done!
