Hi does anyone know anything about the Crossbow Classic control box supplier. I came across it a few years ago but can't find it now, thanks.

It's a Unio Box from Lincoln Binns -> https://lincolnbinns.com/uniobox-66.html

@ Martin did you carry through with your Crossbow build?

Hi Surtdetector,
Got the boards, got the components but have not had time to bring them together yet. MrsB has other things for me to do at present, not as interesting but they have to be done, although I did manage to sneak a couple of days perfecting pulling coil shells on my vacuum former. Should be back in the workshop soon

[surfdetector]

Thanks for the heads up. I will take a look
Boards are now in production a should be with me in a couple of weeks

@ Martin did you carry through with your Crossbow build?

@6666, Did you ever do any experimentation with this type of coil? Thanks.

Missed your post till today sorry, yes had a quick play and it works ok, but harder to make former.

@Martin, Thanks. The Gerbers I posted were the one's obtained a couple of years ago when I was a member of the Mirage and Crossbow forum (Area51). The Crossbow and the Mirage Projects were the first detectors that attracted me to joining Geotech in 2016. My first build was the Surf longboard because I wasn't experienced enough back then to build the Crossbow. Keep us posted on your build. Regards, Marty.

Hiya Martin. Here are the Gerbers for the Crossbow pcbs that Alec used successfully. I don't know if the ones in post #18 are different to these but these are proven. Have a successful Build! I'll be starting a new Crossbow thread hopefully soon. George has kindly given me his consent to write a Crossbow Build Guide that he will review for me before I ask his permission to post it. It will be in accordance with a lot of information from Alec's top class videos and photo's etc that I will be taking as I build along to add to the guide. Hopefully it won't take too long!,,Lol Regards, Marty.

Hi Marty
Thanks for the gerber files. When I get time, i will have a look and do a comparison. Good luck with the manual

Hello Martin,

I had a successful build of the Crossbow Classic and I did a series of YouTube videos of my build here that you might find to be of interest:

Hi Marty,
Did you ever do one of the Crossbow machines or just the Mirage? I was thinking about getting a few Crossbow boards made as the Gerber files are here.
Cheers

I am open to offers for the coil.

I think on this forum that we are more interested in making our own clones
