I first started with trail cameras when my brother bought me a Browning trail camera as a gift. He'd done his homework, and determined Browning was the best option. I now have 5, and I agree, the Brownings are the best.
When I had 4 cameras, I only had 2 security boxes. I put a camera in a pretty remote place, and felt it would be safe without a security box. I was wrong; somebody stole the SD card. I was grateful they didn't steal the camera!
The boxes I had weren't the right boxes for the camera models I had. I bought the Sub-Micro Security Box from Guidefitter. Being the right box for the camera, they fit perfectly. I like that the opening for the security cable is on the bottom of box frame, on the exterior, instead of the interior of the back. Simpler and more sensible. The box itself is sturdy, and as secure as you're going to get.
Through Guidefitter, the order was processed, shipped and delivered before the carrier could update the tracking info! It arrived so quickly, we weren't sure what was being delivered to our front door. Very satisfied with the product, and Guidefitter!
