I live on the Gulf Coast and there are simple, reasonable solutions to keeping you safe dry enough to not damage your guns. I use "kitty litter" in a couple of perforated cans and keep test strips in the safe. When the kitty litter quits working I toast it in the oven for an hour and it goes back to work.Living in the humid south, I'm always concerned about my guns forming rust. In terms of relative humidity, what is the maximum you would want to see in your safe before it gets risky for rust ?
I don't think you need one per say, but it's nice to verify it is actually working. I just put dehumidifier rod in the other day and wanted to see if it is actually doing its job. So far it dropped the humidity 10%. I just have the cheap Lockdown humidity gauge.GaMatt72 said:I have a question. With a dehumidifier rod (I have a 18in lock down) do I need a moisture gauge also?
