Review
Uncapping the
compensation dials sores the first marks for the
LumiZone: on the TruBrite the markings do not
show the same readability as on the LumiZone
furthermore the click identification of the
Truglo unit is not as immediate as on the
competitor :
Truglo reads “1 click= ¼ MOA” … so how much is 1
click at 20 yards?
1) you are very good at math
2) you have the instruction sheet in your
pocket
Excalibur here writes in plain English “one
click=1/2” @ 20 yds”
Mounting the scopes on our test crossbows also
marked a second score for the LumiZone.
The TruBrite scope features a shorter tube that
does not allow much adjustment along the axis.
Also the enclosed rings proved to be a little
problematic (too low) if your crossbow has a
long Weaver rail, therefore we swapped the
Truglo supplied rings with taller ones.
Once mounted we went outside for zeroing and
some field testing.
Here also we found some interesting differences.
The LumiZone has markings for 10-20-30-40-50
yards while the TruBrite has only for
20-30-40-50.
The 10 yards mark facilitates the setup as you
stand closer to the target and should worry less
about shooting out of it.
The LumiZone reticle is very simple and
uncluttered while the TruBrite has a little too
many lines that cover the target, I would give
my preference to the Excalibur’s unit here.
Both scopes can illuminate the reticle, the
LumiZone can be illuminated in 11 gradations of
red while the TruBrite can be illuminated in
both red and green in 5 gradations each.
The LumiZone, having a 11 positions rheostat,
has the advantage of having a brighter high
position and a dimmer “low” position. Truglo’s
adds green illumination that has lesser contrast
(against a dark target) than red and this may
compensate for the lower end illumination
setting.
On the picture clarity both units show clear and
true colors without any degradation or color
dominant but the LumiZone is slightly brighter
(thanks to its 40 mm objective lens vs. 32mm for
the TruBrite)
The LumiZone is also sharper center to edges.
TruBrite is sharp in the center (where you need
it most) but gets softer around the edges.
This is not disturbing as you will tend to
concentrate on the center where your target is,
but indeed the LumiZone is sharper.
