Now you can turn your phone into a ballistic HUD with Desert Tech’s TRASOL

(h/t to Soldier Systems Daily)

Desert Tech’s ballistics app, TRASOL has been updated with a new capability:  A HUD appearing on your smartphone screen that can “track moving targets and provide lead solutions” using the sensors incorporated in one’s device.

Via Desert Tech:

By using your mobile device’s built-in camera and onboard sensors, TRASOL allows users to point their device at their
target and automatically generate absolute accuracy solutions.

The HUD environment has highly intuitive drag and drop tools
for quick input of Range and Wind (without any typing) and the device’s sensors do the rest.  The HUD also allows tracking of moving targets to provide very accurate lead solutions.
Lastly, the photo/video capturing capability allows you to
log your shots easily and share them with your friends.

The ability to track a moving target and provide lead solutions is very interesting.  I have a Newcon rangefinder with this capability, but it is purely for spotter use as there’s no way I can manipulate a long range rifle while holding it.  The rangefinder is also far more expensive than Desert Tech’s app which is a very reasonable $9.99.  TRASOL doesn’t quite approach Trackingpoint’s capability, but it’s nice to see a HUD capability within ballistic apps.

As seen in the short clip above, the app can track a designated target, calculate its speed and provide lead solutions.  There is a caveat, however.  The user must input range to target and wind speed data, so a laser rangefinder is still a necessity.  I personally don’t shoot with a smartphone mount on my rifles, but I know they exist. Mounted on one’s rifle with a quick rangefinder like Silencerco’s Radius, it could be a good solution for solo shooters to quickly engage moving targets at range.  I’d like to test it out to see if the app can adjust for range on a moving object after the initial input, however, as that data can make a huge difference in shot accuracy.  Another reservation of mine is that the drag and drop capability for inputting range and wind speed data might be a bit hard to do while trying to engage a moving target.  Those potential issues aside, paired with a rail-mounted rangefinder like Silencerco’s Radius, it could be a good solution for solo shooters to quickly engage moving targets at range.

    How about a sensor package that is attacheable to a standard picatinny rail that will provide all the needed data to a smartphone and is zeroed to your rifle? Then you could dock your phone to the rifle to use as a “scope” but it would allow for shooting around corners, from the hip, etc. provided you saw the output on the screen.

      Intelliscope is nearly what you described, minus the ranging and target designation. Otherwise, trackingpoint has a package combined with glasses and a HUD that has all the capabilities that you described, just doesn’t use a phone.

        The trackingpoint system is interesting, but it’s really a one gun solution configured for precision shots. I would think there is a market for a scalable add-on package that will work with any old regular phone or tablet. And I think the real value of this technology is in battlefield awareness and communication, not just “making the shot”. That is in my experience the most difficult thing in any military op.

    Great, another cool App to suck more battery power out of my Android phone which already has poor battery life. I need to invent a small portable wind turbine that I can hook to my phone’s micro-usb port that charges the phone AND determines wind speed and direction too.

      Will it come in muddy girl?

      All phones seem to have poor battery life if you do anything aside from text and talk. I carry a 10k mAh battery and can run it all day operating a business, taking photos and video. It was an inexpensive solution to a huge problem.
