There are 4 flavors of RAPTAR
01 - ES Lite (ES = Eye Safe) ... this is the lasers and illuminator only, no LRF.
02 - ES ... this one has the lasers, illuinator and the LRF.
03 - S ES ... this one has the blue tooth/ballistics module on top of everything 02 has.
04 - S ... this one has the full power lasers, illuminators and still the same eye safe LRF as well as the blue tooth ballistics module.
I have the 02 ... it has a red vis laser ... I use that in the house to zero the laser to the reticle of my day scope, so it will be "in the ball park" when I go out at night to actually zero the laser to the reticle.
I use mine as a rifle mounted range finder, just like I use the Radius. They both get the job done ... out to 1,000yds which is as far out as I've tried.
The RAPTAR is smaller and lighter than the Radius. The Radius can be zeroed to the reticle without tools.
I zero the RAPTAR an the Radius exactly the same way.
Here is the zeroing package I used one night.
I carried everything outside mounted on the gun, since I wanted to make one trip and I had to carry the tripod also.
Then I dismounted the clipon.
I had already ball park zeroed the vis laser to the day scope reticle in the house.
Then I turned on the pvs-14 mounted on the rear of the day scope via the Night Optics "Day/Night" mount.
Then I turned on the ir-laser in the RAPTAR (if zeroing the Radius I turn on the viz laser of the Radius).
I located the target I am using to zero. Preferably something as far away as possible an small enough to be distinct, but not too small to hit with the laser.
Then I adjust the windage and elevation of the laser and co-witness to the day scope reticle. I am now ready to test.
I turn off the laser and the PVS-14 and flip the PVS-14 to the side, then mount the clipon and power it up. Then I range various known distance objects by aiming the day scope reticle at the object and pressing the range button. If the reticle and LRF are matched up I should get correct readings. If not I repeat the process.
Both the RAPTAR and the Radius seem to be holding zero just fine for me. Here they are on the 6.5G(18) on the left and the 5.56(18) on the right.
Since you can buy several Radiae for the price of one RAPTAR (02 or above) and since I haven't detected any functional difference between them yet, I can't recommend the RAPTAR over the Radius at this point. I have not refreshed the zero on the Radius in > 2 months and I've shot several hundred rounds with it. The RAPTAR should be more rugged and reliable, but the Radius has not failed yet.

Any illuminator should get you out 200yds.
