my brother stopped over & he had a site pin that glows all the time . he said it was powered by a nuclear bye product & will last 10 years. he has had it for 4 years but doesnt remember where he got it
my ? is were can I get one
thanks Gregg

It's probably a pin made with tritium.

yes i would agree its probably just a tritium pin. cabelas has them for about 25$ i think

I give him a call & yes it is that sight . I will be ordering one . it does not have the glow around the pin & you dont have to turn it off
thanks Gregg

Will it make your hair fall out?????

I've got tritium pins on 2 bows and they are great for hunting. Always lit, day and night.

i have been looking for them locally but cant find anyone handling them
any one know of some one online ?

robbymi go to cabelas [CABELAS] they have em for about $25

The other posts are right on the money. "Tritium" Not nuclear, but they are radioactive. Similar coating material that's applied on watch hands for luminescence.
