Hawkeye borescopes seem to come in 3 flavors, a fixed focus, straight eyepiece; a variable focus, straight eyepiece; and a variable focus, angled eyepiece. The fixed focus version is least expensive, while the angled eyepiece version is the most expensive. Will the fixed focus version serve most needs for inspecting barrels? Or do I need to jump to one of the variable focus versions?
