A Dead Strip normally used with hand routed tracks and commercial braided tracks. Reed switches are often used in custom routed HO tracks.
Unfortunately, at this time, none of the major track set manufacturers produces a four-lane (or higher) Analog lap counter. You do have options, however. (We will cover the 4 lane options as this is the most popular.) We sell DS
lap counting systems.
DS-300 is the base unit. As a stand alone, it works for up to two lanes; add DS-334 for lanes 3 and 4. You will also need a light bridge to go with this, try DS-37 for Carrera, DS-26 for Scalextric,
DS-55 for Ninco. Unfortunately, DS is pricey and hard to keep
in stock. But they are extremely reliable and accurate and would be
your best option.
Another possibility is a PC based system. We recommend TrackMate for that, especially in a 4 lane setting! TrackMate uses a Dead strip or REED switch type and includes all the parts you need to get a PC lap counter setup.
We have also heard of people customizing two-lane lap counters (such as the one by Carrera). If you are handy, this would be the most economical choice. Unfortunately, we tried to do this for a customer once, and we couldn't figure out how to do it. Only recommend you try this if you are an 'engineer'! Using two two-lane lap counters is not a problem with a road course type layout. Simply insert them in a chicane area designed into your track. Of course this is not possible in an oval-type configuration. In lieu of a lap counter, you can run your races on the honor system where each individual counts their own laps. This method is quite effective when you keep your races short (say 10-12 laps) and if you are running on "crash and burn" race rules, where racers are automatically out of the race when they go off the
