Product Review: Mantis X3

On this bog we've talked about the importance of shooting practice, particularly dry fire practice for improving skills, accuracy, and confidence. Erin has reviewed several dry fire systems on her blog. Such as the LaserLyte targets and emitters.

(As an aside, the product I'm reviewing here is another fruit from the Gun Owners of America GOALS event I attended earlier this year. I highly recommend it to any of our readers who can attend next year.)

Overview

The Mantis X3 is a small rechargeable unit that can be attached to any handgun or rifle that has a Picatinny accessory rail. For firearms without a Picatinny rail, Mantis also makes adaptors that attach to the bottom of a pistol magazine. 

The X3 works by detecting the amount and direction of movement during trigger pull. In conjunction with a downloadable app, it enables dry and live fire practice whenever and wherever the owner desires. The Mantis X app is available from the Apple, Samsung, and Google play stores and will work on any mobile device that has Bluetooth capability.

What You Get

The Mantis X3 comes well-packaged in a foam lined zippered hard pouch, and includes the unit, a charging cable (USB A to Micro-B), and a printed quick start guide. More detailed instructions and information are available through the app or downloadable from the website.

Mantis X3 Package Contents

 

Weighing in at just under half an ounce (or 13 grams), and measuring 1.3 inches long, one inch wide, and 0.75 inches high, the Mantis X3 is unlikely to affect the handling characteristics of any firearm (with a possible exception being if the user wants to use it in conjunction with holster draw drills).

Setup of the Mantis X3 is extremely simple.

1. Download the App
2. Attach the unit to the firearm
3. Connect the device to the app via Bluetooth
4. Start practicing

The unit I received is occasionally a little finicky synching to my phone. I don't know which side of the connection string is causing this, but I haven't run into that issue with other Bluetooth items or when connecting the Mantis to my tablet.

Once the app is installed and connected, a variety of options for firearm type, shooting hand, mount location, unit orientation, and even live or dry fire modes can be selected.

Mantis X App User Options

There are a number of Training Drills built into the app, including a rotating series of Daily Challenges. Some of these options are timed, while others are not.

The Mantis X app also has a weekly shot goal. When reached, it will play a fanfare and display confetti drifting down the screen to mark the shooter's achievement. I found this to be a nice, fun feature.

Dry Fire

To use the Mantis X for dry fire practice:

1. Go through the setup steps I mentioned earlier
2. Select a convenient target, or prop the tablet or smartphone up at an appropriate distance.* 
3. Double check to make sure the firearm is unloaded
4. Start the selected drill.

* Since the Mantis doesn't rely on a laser or something similar, any aiming point will do, but I like using the provided on-screen target for dry fire drills. 

Mantis X App Drill Screen

I installed the app on both my smartphone and a tablet. I use the former when practicing at shorter ranges, and the latter when I have more space to work with. There are plenty of stands available through retail sources to hold either the phone or tablet in good positions for practice, and all sorts of phone stand 3D print files can be found on sites such as Thingiverse. In a pinch, a plate stand works as well.

Once the practice session is done, the Mantis X app provides the user with a variety of feedback details to review. Accuracy is obviously measured, but also elapsed time between trigger pulls, overall time, muzzle movement, and even firearm cant. In addition, it has the ability to compare multiple sessions over time, giving a clear metric of improvement and noting any areas which need attention.

Live Fire

I've utilized the live fire drills less frequently, mostly the Shot Timer. When activated, there will be a two to five second delay then a buzzer will sound. At this point, I can fire any number of shots at any pace. Settings can be changed to fit the shooter's preference for delay and number of shots per string.

I've run this drill with both slow, considered fire, as well as rapid fire. It's certainly more fun than dry fire drills, but it's limited to when I have time and access for live fire. It also consumes ammunition, which can get expensive quickly.

My Experience

As already mentioned, there are a bunch of practice options included with the app. I've mainly focused on the basic marksmanship Open Training drill. This is untimed accuracy practice, with any number of shots at any pace. Unfortunately, the only pistols in my collection with rails are both striker fired, which currently makes the timed dry fire drills less useful for me.

I've also found if I rack the slide too sharply to reset the pistol, the Mantis unit occasionally registers the slide returning to battery as another shot. This obviously doesn't do my accuracy scores any favors.

Yet even with all that, I've found after only a few training sessions, my sight picture was steadier and my trigger pull was smoother. I just need to make sure I put aside regular blocks of time for additional practice.

Pros and Cons

As far as dry fire training systems go, the Mantis X3 has a number of major benefits. It's small, lightweight, and rechargeable. Installation and use are very simple, and the app is quite versatile and user friendly. Even better, it allows us to practice with our own firearms, so there's no need to adapt to new weight, balance, or trigger pull.

The primary negative element is one common to nearly all dry fire training solutions, and it is not the fault of the unit: since the Mantis X3 reacts to a hammer or striker releasing, it requires re-cocking the action after each shot. Unless you are shooting a double action firearm, this will slow down practice and add some amount of frustration. Even a single action pistol with an exposed hammer will add extra steps to the training process. Again, this isn't the fault of the Mantis unit, but simply a technological reality. Fortunately, there are products on the market to help address this issue, such as those offered by DryFireMag, and I hope to get one of these for testing and evaluation in the future.

Another aspect of the product some people may object to is the necessity for a smartphone or tablet. Considering the vast majority of people are likely to already own one or both, this is probably not a deal breaker for most potential users.

My Rating: 9/10

The Mantis X3 is an excellent unit for improving sight alignment, trigger control, and confidence. It could be especially useful for anyone who travels frequently, as they would be able to practice in their hotel room.

I give the Mantis X3 an easy rating of nine out of ten.

Practice safely, and practice often.
