The wireless fitting kit for the M27/M47 is available now. It's exactly the same as the existing wireless fitting kit for Blinder M20/M25/M40/M45. There are no changes required.
The only thing that are different is the connector cable and that you currently have to disable the start up tones on the M27 using the Blinder Software, which is a snap.
There are no changes to the price. MSRP remains at $174.99
I suspect what you're really asking is when is the M27 jammer coming out.

Well I can exclusively reveal.................................nothing. Sorry I don't know. I think I said elsewhere that Blinder had always set the target date for around the middle of July, but these things are always fluid. From experience of launching several products, I can confirm it's a bit like building a house....it always takes longer than expected and costs you twice as much as you planned. With any new product, there's always last minute unforseen stuff that comes up that you have to deal with and the smallest thing can cause delays. I'm sure the guys at Blinder are working their socks off to get this out as soon as possible.
