Home Forums Hunting & Shooting Alaska electronic sights for bears and other dangerous game

I forgive you for the bandcamp comment...that was hilarious.

Polskas "inquirery" and the incredulity by some professional users prompeted me to do a simple test.

Unit tested:

Aimpoint Micro H1 powered by 1 new Lithium CR2032 battery
(in accordence with Aimpoint Specs)

Function test modi:

1) continous - unit switched on - Red dot is lit y/n
2) toggle - unit is switched on/off and brightness changed - Red dot lights/switches off/ changes intensity y/n

Function test environments:

1) roomtemperature: 18�Celsius
2) freezer: -30� Celsius

Reason for testing:

Per Aimpoint spec sheet the unit will work from -30�C to + 60�C. Aimpoint advertising has many words for the reliability of the devices.

My device failed to switch on twice in the field at subzero temperatures around -5 to -10�C.

So - I wanted to know - Does leaving the device switched on solve the issue?

Results:

Mode 1 at room temperature - all works.
Mode 2 at room temperature - all works.

Mode 1 at -30� Celcius - nothing works.
Mode 2 at -30� Celsius - nothing works.

Switching to a warm battery in the frosted sight - all works.

Conclusion:

The tested unit is not reliably used at subzero temperatures.
The expierienced failures in the field were not random.
Source of failure has been identified as the battery. As batterys of the highest quality have been chosen - there is no room for improvement left.
As the battery has been identified as the source of failure - leaving the unit switched on does not make the unit usefull in subzero temperatures.

Results may differ with different models/battery types, as can be reasoned that the flat CR type cells are easily affected by cold.



Knowing trumps guessing - using these for brown bear hunting is foolish.

Thanks for taking the time to test this!

Li batteries are crap in the cold. NiMH aren't much better. Good old NiCad's work the best (but aren't that great either....). Anyone who uses Cordless Tools figured this out a while back (no slight to you Mr. cmg).

One more reason....

Nice work cmg--very good to know!

I don't think it matters whether this Pole is male or female; fact of the matter is "it" is a disgrace to the nationality. I have known some real great Polish people who were bright and masters of their trades. Polska whomever you are may be well educated and spoiled by your Daddy but you're also showing the resemblance to the backend of a horse. You have asked question after question and challanged the answers from people who have held the plow in the ground to get the right to give the answers. You have driven one from this forum and you owe some sort of apologies. Kotzy

Please tell who that was?

Don't worry.

458 has been around to many blocks to many times to be chased of by any trolls.

Was last online 27.12.

I didn't feel chased off - I gave my opinion and then followed the advice given to me by my son who says that argueing on the internet is like running in the special olympics - even if you win you are still retarded.

What a scare!!! I was sure Phil had lost his nerve over a deranged Pole on the prowl!



















NOT!!!!!!

I hope my sons will give me the same sage advice when they are a bit older. (They are soon to be "smarter than their Dad" which means it'll still be a few years I imagine. )

So, what would be the maximum prudent threshhold before you pull the trigger on a charging bear intent to get a piece of you? Say you are holding a lever 45-70 and here he comes. How close do you let him get before lights out?

IIRC, when Phil posted that, he was referring to a hunting situation.

As I'm sure you know, each time is a different situation.

Of course, you realize you would be speaking German if it weren't for us (U.S.) ?
Should you choose to disagree just revisit your learnin'. History class hasn't been that long ago for you, has it?

sorry for chasing people away. How about the t-1, not the h-1. the t-1 is supposedly a little tougher and night vision compatable. I think I will go with a t-1

I think anything that has even the slightest chance of making you a bear turd is a good route.

Sounds perfect for those night hunts for bear and other dangerous game!

Jeff

Definately go with the t-1.....it is night vision capable which will come in handy on virtually any bear hunt.

Do not bother actually reading any posts.

The T1 uses the same housing and the same battery as the H1.

My thinks - Steelhead called this one.
