Over the years we used one type of led with one type of switch for our blast markers. We always keep an eye out for better technology to improve with the performance and durability of our blast markers. I am please to say that some of the technology I have had my eye on for a while has finally come down in price. What does that mean? It means we will still be able to sell quality blast markers at a very affordable price still, with much better components such as better power source for longer batteries life better switches and better and brighter LED's keep your eye out for these new markers to hit the shop soon. And thank you for supporting our small business.
