ALGE will begin offering double sided D-line displays for running races, triathlons, etc. Starting June 1st these tripod mounted displays will be available in both 15 and 25cm versions. They will be powered by 110/240 VAC or EXTERNAL 12vdc battery. They will not be offered with internal battery pack or charger. We are expecting that they will be about 9cm thick (3 1/2")
