For a begginer thermal for about $1400 it's mind blowing. Some of the comments you read are people who are spending $3000-$8000 on top of the line thermals. I picked up heat signatures from deer in a clear cut early in the morning out to 400 yards, then put my binoculars on them and looked and looked and eventually would see movement to identify the deer. I've never seen so many deer from that stand ever. I used the Sig echo just to see deer from my stand and didn't mount it. I bought it to hunt pigs on our food plots at night after deer season. Our timber lease food plots are not huge. The longest shot is 80-100 yards. The echo 1 at 80-100 yards gives you identification and shot placement no problem. After using it this season I'm amazed. I know if I upgrade to a 60Hz unit for greater distance and resolution I'll be spending over $4000. This unit is great for my hunting property for 80-100 yard shots. I'm not ready to dump a huge sum of money to hunt pigs. It does take a hunt with it to get used to it and know what your looking at. I will post pictures here later today of deer at different distances. I will say if money is no object, get an $7000 unit.
