I have been informed that dew heating bands can't overlap by more than 0.5 inches. What are everyone's experiences with this?
Specifically, I need dew bands for three camera lenses with maximum circumferences of 9.04 inches, 10.1 inches, and 11.4 inches. Is it possible to use a single 12-inch heating band for all three lenses or do I have to get a different sized band for each lens (much more expensive)? Only allowing 0.5 inches of overlap would also require custom sizes of 9.5 inches instead of 10 inches and 10.5 inches instead of 11 inches and 11.5 inches instead of 12 inches.
I had thought that you could velcro the ends of the band at a right angle to form a looped ribbon shape but apparently this is not recommended. If the band is 1.25 inches across, even connecting at a right angle will overlap for more than the minimum overlap of 0.5 inches.
