Does going from 95 ° F to 0 ° F retain the POI well?
At one point 2 years ago I had the MKIII 60, Reap 60, Reap 35, and Patrol M300W, all were zero'd at 100M (110yds) in 0-20° F degree temps. They were used throughout my season (temps ranging from -30 to 75° F, and were acclimated from winter into spring with at least a 90° F swing, I didn't have any issues.
I had 2 pulsar units, XP50 trail and the XP50 trail 2 LRF mod, same zero process and acclimation period, with numerous rezero's having to be made.
We've currently used 2 Rico MK1 640's, only difference in the zero process was it was raining, then converted to sleet/snow mix while they were zero'd. There was a point in time where we quit killing from March (depredation) up until July (more depredation) and went to verify zero on both units again, at 100M (110yds) only not in rainy sleet, but in 75° F comfort... No shift no issues, take it for what it's worth, that's just my experience.
Regarding the names of these units, it's not that difficult to understand.
You have the Rico MK1's a 640 (RH50) unit and a 384 (RL42) unit.
You have the Alpha ( an upgraded MK1 640 with more options) Bravo (upgraded MK1 384 with more options)
I have no idea what the SCP19 256 or the SCT35 384 are, (maybe a euro thing)
IMHO, the Pulsar names is a $hit show. You have the Helion XP50, Helion XP38, or the Helion XQ50, Helion XQ38F , Lexion XP, Axion XM30, Axion XM30S, Axion XM38, Axion XQ38, Axion XQ38 LRF. Accolade XP50LRF, Accolade XQ38LRF, Accolade XQ30, Accolade XQ50.
Now the weapon sights,
Apex XQ50, Apex XQ50LRF, Apex XD75, Apex XD38A.
Trail XP50, Trail XP50LRF, Trail XP38, Trail XP38LRF, Trail XQ50, Trail XQ38.
Trail 2 XP50LRF, Trail 2XQ50LRF.
Thermion XG50,
Thermion XP50, Thermion XP38 Thermion XQ50,Thermion XQ38, Thermion XM50, Thermion XM30, Thermion 2 XP50, Thermion 2 XQ50, Thermion 2 XQ38.
Granted, I know the numbers are not that difficult to understand. BUT for the average consumer who's looking to get into this, yes it may honestly be intimidating and overwhelming.
