Hi Joe, the T1-10 will be back in stock and available again soon.
Hi speedybill the updated info is coming soon at www.rclaps.com
including costs and shipping etc. There's a new 'shrink' PTX version and a custom purple LED option amongst other things. Free shipping offer also coming too!
Hi magm20001, the PTX has 'generic' numbers which can be changed, they're like the 'RT' handout/loaner transponders with sets of 10 numbers from 1 to 10. The 20 number PTX has two sets of numbers from 1 to 10 so up to 20 numbers can be used together. As long as it's possible to select a number that's not being used in a race it's ok.
