First Focal Plane spotters – The Black dot test strikes back!

First Focal Plane spotters – The Black dot test strikes back!

http://ift.tt/2yctdRq

In Finnaccuracy’s previous test, the mirage limited the dot visibility significantly.

In case you missed the previous extensive review of reasonably priced FFP (First Focal Plane) spotters you can read it here.

In this test, the weather seemed to be very good for spotting, so we thought we would give it another try.

The temperature was +7.5C / 45.5F, with light winds and clouds. Very little or no mirage.

The reference table with dots was the same as in the previous test. In practice, a pitch-black sharp-edged dot is easier to see than an actual ragged bullet hole, but for the sake of repeatability we decided to go with simulated holes.

Also triangle-shaped forms next to the dots help spotting. It is easier to spot a tiny detail when the eye can be pointed to exactly the right position.

The only scope used in this quick-test was the Bushnell 15-45.

As the previous review showed, its practical performance was somewhere in between the Sightmark 15-45x and 20-60x. In practice, the bigger Sightmark would have given much longer distances.

Here’s the verdict of the Bushnell 15-45:

505m/552yds  – all dots visible

555m/607yds – .224 gone, 6.5mm smallest visible

600m/656yds – 7.82mm smallest visible

700m/766yds – .338 smallest visible

800m/875yds – .50cal only. Probably it would have been able to see it 50 to 100 yards further away.

 

Below: 315m/345yds.

Images has been improved to bring appearance closer to actual. Still blurrier than actual view.

700m / 766yds
