Dino Roy Posted July 28, 2020 Share Posted July 28, 2020 Hi - I have a mint Coinmaster 1 TRDX machine that I got at a yard sale. It has all of the components and fired right up with fresh batteries. I was just tying to find out when it is from exactly but can't seem to find it online. It has a Date of GG. It's a fun machine to use as it brings back old memories as a kid in the 1970's out finding stuff with a similar machine my buddy had. Thank you in advance for your time, Dino Link to comment Share on other sites More sharing options...
PimentoUK Posted July 28, 2020 Share Posted July 28, 2020 It would be interesting to see if anyone does know the 'secret'. I have a Coinmaster 2 hipmount version, date code is HD. The few electronics part with any obvious date codes are an IC dated late 1978, and the loudspeaker appearing to be 1980. This is a Savo Scotland produced machine, so may not necessarily match a US-made one. I would suggest looking for date codes on the inner workings. IC's ( if it has any ? ), the loudspeaker, electrolytic capacitors, the potentiometers. 1 Link to comment Share on other sites More sharing options...
Dino Roy Posted July 29, 2020 Author Share Posted July 29, 2020 Hi - Thanks for your reply. I'll dig around a little on the inside and see if there's anywhere else that might give a clue. I was hoping there was a list somewhere out there but so far have come up empty. People list their date code when they sell them, but the dates the list just look like a guess/range. I also tried to find a date range for when the model was produced, but haven't been able to track that down either! Cheers! Link to comment Share on other sites More sharing options...
Dino Roy Posted July 29, 2020 Author Share Posted July 29, 2020 Well, Whites still has the manual up online - but no dates anywhere in it... cm_1_tr_dlx_instruction_manual.pdf Link to comment Share on other sites More sharing options...
PimentoUK Posted July 29, 2020 Share Posted July 29, 2020 Their catalogues are a guide to when a machine was introduced, though they no doubt would be manufactured for a number of years before being discontinued. Here's a French website, with pics of your machine, catalogues:whites detectorswhites catalogues and Sven's site has many old catalogues too:treasurelinx site Link to comment Share on other sites More sharing options...
Dino Roy Posted July 29, 2020 Author Share Posted July 29, 2020 Hi - Thank you! These are fantastic! The actual date codes still seem elusive, but I feel like I am honing in on a range. I saw the same question asked on other detector/treasure finding forums but no one knew the answer... Maybe there's an ex-Whites employee out there that know's the secret.

Snake Eyes Posted August 17, 2020 Share Posted August 17, 2020 @Dino Roy I noticed that the manual does have a date on it, revision of April 1974. I could be wrong, but I thought the the double digit code was as follows, based on the old machines I have GA -1971 GB - 1972 GC - 1973 etc so in theory GG would be 1977 1 Link to comment Share on other sites More sharing options...
PimentoUK Posted August 18, 2020 Share Posted August 18, 2020 I think it's more obscure than that, probably intentionally so. If you look at that French website, and compare the Coinmaster1 TRDX, Coinmaster 2 TRDX and Coinmaster 3 TRDX, they have date codes of GL , K4 , R4 respectively. They all appear to be similar in vintage, though - the same big box, big coil connector. I suspect they update the date code on a monthly or weekly basis, and probably miss out a few letters to obfuscate things. Here's a Pinterest page showing a Coinmaster 1 TRDX listed on Etsy, it has a date code of L4:pinterest CM-1TRDX Link to comment Share on other sites More sharing options...
Dino Roy Posted September 10, 2020 Author Share Posted September 10, 2020 Thanks Snake Eyes - That looks about right. If it does change 1 per year... I don't have any others and I couldn't find enough posted online to put the pieces together! Link to comment Share on other sites More sharing options...
