Reply to "Alge photocells in blowing snow"

mosMember

We were using reflectors for the race that caused this post. Issues included snow building up on the reflector as the wind changed direction.

My instinct has been that the old rectangular Alge photocells seemed to have a wider tolerance to horizontal/vertical movement, than the PR1a, I've often wondered if it's instinct or fact. Having used them for years, I've never really looked into how photocells work.

Do different types of photocells have different widths of beams, or use different amounts of power, which make them more or less reliable? Does using a C-cell battery vs TDC cable make any difference in PR1a performance?

In addition to using a through beam, are there any brands of photocell which have more tolerance to false finishes from things like dense snowflakes?
