Definitely won't see far with those cams. In dark spaces they are only going to get you at most 18-24" from the scopes light source. If the room was well lit of course like you were spying on a neighbor watching tv, it would see the whole room.

The light just isn't strong enough in gaps and voids to see far enough, a limitation that isn't often discussed so a good point!

On a side note, I bought the extended version that will allow you 9+ feet on that milwaukee, but usually you can't get it that far unless no insulation, no debris or other that will cramp up the snake as it goes.

Something to consider before spending extra cash...

I have one from Harbor fright. I had a crack in my sidewalk and the sand was gone and leaving a void. The brick pavers beside the side walk were sinking. My sewer line run right were the crack was. I was thinking the sewer line had a brake in it! I removed the brick paver and seen a tunnel, I look down the tunnel with the scope to find it was a mole run. NOTE, before doing this I put beach sand in the crack and it kept going down. Put the brick paver back and am good to this day, paid for itself right off. I used it to find a oil leak in my motor cycle. People are sure impressed when you bring it out to check for a bat when you just have one that was flying around.

Mine came with a 1 meter snake (39") and you can't see much further than that.

THATS why I had to drill another pair of holes, to see below the cross bar tween the studs.

i got asked by a mother of a 19 year old girl if i would spend the night in her room with her to make sure i got the bat out.. i had got one right when i got there... but found no other one... the daughter begged me to stay... needless to say... i didnt dare...

They obviously did not know that your Internet name was "wiggler"!

2nd UPDATE

I haven't caught anything, even in mouse traps on top of the foundation in crawl space OR attic.

She says she still hears scratching on metal at night, like the duct work.

Anyone take apart ducting?

NO, I have NOT been on this hot and heavy since July....have to help her when I'm up that way, 1 hour North, BUT have swung by about 8 trips, now.

had a customer with noises in the wall, low outside corner in the bedroom. saw nothing with the scope. made three or four trips, but I never heard anything. So a couple weeks went by and the foot of snow melted outside. It was then I could see vole tunnels up to the house. they were going up in between the vinyl siding and exterior chipboard, but not into the house.
