LaserLyte Training Target Registers Laser Beam “Hits”

laserlyte training targetIf you have a laser fitted to one of your firearms, here’s a training gizmo that can help you practice your aiming and target acquisition. The LaserLyte Laser Trainer Target can register and display “hits” on its large bullseye display using 62 laser-activated LED lights. Under normal conditions, this laser-activated target can register shots up to 50 yards away. The $140.00 (street price) Laser Trainer Target is good for about 6,000 “shots”, drawing power from three (3) AA batteries. The unit is fully independent — there is no hook-up to a computer or separate processing pack.

Though it may appear smaller in the photos, the Laser Trainer Target is about the size of a school textbook: 9.5″ H x 6.25″ W x 2.0″ D, with a target area roughly five inches in diameter. The device can be used inside or outside, but you’ll probably get best results indoors. The Laser Trainer target can function with all user-activated lasers, such as grip lasers, front rail lasers, in-chamber “laser cartridges”, and even laser boresights (so long as they can be activated by trigger movement).

Ruger LC9 LaserFun to use and easy to deploy, the LaserLyte Trainer Target was named a 2012 Golden Bullseye Award Winner by American Rifleman magazine. MSRP is $219.95 but “street price” is WAY lower. These units sell at WalMart for $139.41. That makes it affordable. Of course you don’t experience the noise and recoil of actual shots with the LaserLyte Target Trainer, but the device can easily pay for itself, if you compare the cost of batteries vs. live ammo. These days, 1000 rounds of 9mm ammo can cost $400.00 or more.

WARNING — UNLOAD FIREARM FIRST: When Training with the LaserLyte Training Target and a firearm fitted with a laser-emitting device or laser sight, always remove and unload the magazine and then double-check to ensure the chamber is empty, and the gun is unloaded. If there is a live round in your gun, not only can you destroy your target device, but the round could cause injury or death to someone downrange.

Lapua Releases Doppler Radar Data for Lapua Scenar-L Bullets

Lapua has done extensive field testing of its bullets, using sophisticated Doppler radar equipment. Employing radar, Lapua has logged actual observed trajectories with a variety of bullet and cartridge types. And Lapua has just released updated radar data for Scenar-L bullets used with 6.5×47 Lapua, 6.5×55 Swede, and .308 Winchester chamberings. You’ll find this new data incorporated into Lapua’s product description tables for these three cartridge types.

Lapua doppler radar dataYou will also find both G1 and G7 BCs for the new line of Scenar-L Bullets in Lapua’s updated Components Table. Ballistic coefficients are based on Doppler radar data and calculated by Quick Target Unlimited Lapua Edition.

To find the BC for a particular bullet, go to the Components Table, select the caliber (on the left) and then look for the G1 or G7 value on the right for particular bullets. For example, the BCs for the new 136gr 6.5mm Scenar-L are 0.545 (G1) and 0.274 (G7).

If you are looking for the most precise trajectory predictions, nothing beats real-world testing like this. Bullet BCs can be calculated, “on paper”, from bullet size, weight, and shape. However, in the ‘real world’ the actual aerodynamic drag forces acting on the bullet change with velocity and other variables. Therefore, a bullet’s BC is NOT actually constant at every point in its flight path. Doppler radar allows Lapua to observe the actual drop of bullets at multiple points along their trajectory.

How much more precise are Doppler-radar-based trajectory predictions than typical drop charts based on modeled BCs? Consider this… when you plug the radar-based numbers for a .338 Lapua Magnum into Lapua’s ballistics software, the error in elevation is less than 2.5 cm (1″) at 1,500 meters. By contrast, the error based on a traditional G1 BC model could be over 1 meter (i.e. more than 40 inches).

Free Lapua Ballistics Software for Android OS Devices
If you want to use Lapua’s Doppler Radar data for your own ballistics calculations — there’s a App for that. Lapua’s Quick Target Unlimited (QTU) software for Android OS can be downloaded for free from the Android Market. Predicted trajectories for this software are based on precise Doppler radar ballistic measurements of Lapua bullets, making this program much more accurate than other ballistic programs for mobile phones. Note, however, the Doppler Radar data is offered ONLY for Lapua-made bullets. This App does NOT include radar data for Berger, Sierra or other brands of bullets.
