Viasho Portable Laser Group Buys

Viasho portable laser systems low cost, small size and light weight make them ideal for outdoor or field use where access to the power grid is not available. They're also perfect for applications where quick set up time, limited space and very low cost are imperative. Group Buy details : • Laser specs and some components are lower performance than the RPL series to reduce costs (see specs below)
• Carrying case, batteries and charger are optional at additional cost
• Lasers are black in color, with keylock tailcap (non-adjustable).
• Not eligible for the Optotronics upgrade program.
• They are rated at peak power output, average sustained output above rating is not guaranteed.
• Warranty is 90 days ( through Viasho, not Optotronics)
• There are NO refunds on GB orders after the order is placed, only warranty coverage through Viasho directly.
• Group buy orders are placed between the 15th & 20th of each month with customer delivery no later than the 15th of the following month.
