I, too, recently found a need for a borescope and visited this thread. With the cooler weather approaching, those dang mice are looking to come indoors. My wife and I were awoken with what sounded like scratching from inside our bedroom wall... last year we had a mouse die inside another interior wall and certainly wanted to avoid that from occurring again! It can be difficult to ascertain with absolute certainty which wall cavity the mouse had fallen into - I did NOT want to start drilling multiple holes with the hope to lure the unwanted visitor(s) out. Depending upon several factors, all stud spacing can deviate from the standard 16" on-center spacing with some studs being closer and determining the mouse's exact location between two adjacent areas can oftentimes be difficult.

After looking at multiple sites describing 'removing mice from walls', it appeared that the consensus solution was to drill a nickel-sized hole (0.835") into the wall and set up a box with a corresponding hole against the wall hole. My plan was to drill a small exploratory hole into the wall, check if occupied with a mouse, repeat as required until the creature is found and then drill the larger hole to allow the mouse to exit – a small diameter borescope sounded like the right tool for the job!

Several folks here had shared their experience with the Depstech borescopes and the online reviews spoke very favorably as well. A dual lens was required for my application because just looking forward would leave most of the wall cavity hidden from view... I suppose contorting the borescope's end piece to the left and right could permit viewing the side areas BUT the inclusion of dual lens would definitely aid in its usability.

Depstech has a newer model that has a smaller diameter (5.5mm / 0.22") end piece that is also equipped with dual lens AND has its own display. My thought was that if I miss the mouse with my first attempt that it is way easier to patch a couple of 0.22" diameter holes than a couple of nickel-sized holes - so I ordered the Depstech DS380DL (at that time it was $67 but has gone up to $80 now... still, this is way less expensive than having a professional exterminator come in and do this PLUS I essentially get a free cool tool!). My only concern was with the rather short focal lengths listed in the specifications: front viewing focal length was 3 - 8cm (1.18" - 3.15") and the side viewing was much less at 2 - 5cm (0.79" - 1.97"). Given that if I drilled directly in the middle of the wall cavity, I was unsure about how good the viewability of the inside corner areas would be.

The Depstech DS380DL arrived and ALL concerns about the focal length quickly disappeared - I just needed to see if a mouse was inside the cavity, not examine the texture of its eyelashes (however, the clarity and detail beyond the maximum focal lengths listed were IMPRESSIVE!). I only had to drill one hole and, following the box-with-a-hole method, the mouse exited the wall on its own after about 60 seconds! Problem solved!!!... well, until it happens again...
