External bridge or not? Sigma Verifier

[Silverman2U]

Hi all would appreciate any thoughts or feedback. I did a lot of research into getting a sigma verifier a while back in November 2020 and hot a little put out by the taxes now due. I am now prepared to “bite the bullet” though they are now finally back in stock.  
 

I am not sure if I want the bridge though. 
 

I was thinking the large wand attachment should be good enough to verifier a 1 Kilo Metalor bar. Max I would buy privately or me prepared to verify for a third party.

It’s like 2000k for this setup… if I can use a plug in wand for the occasional 1 kg bar I don’t think I want to pay another 600 for the external bridge option.

I’ll happily tell you what I did, I don’t buy bars, so I just went with the Sigma Pro.

For coins it was more than sufficient for me and definitely works on all my coins and sovereigns, found 2 1oz Silver fakes, which were so obvious afterwards 🙄 kept them them to remind me.

The rest I tested, pictured and sent off to storage, safe in that knowledge. The 1kg bars I had would show up under the wands, I’m not 100% sure those wands do penetrate all the way through though? Others may know better.

I only have the original version of the Sigma, not the pro, so my information might not be totally accurate.  The bullion wand does give you a bit more depth, but depending on the dimensions of the bar, even the bullion wand won't be able to scan it entirely.  The best you can do is scan multiple locations on every side of the bar to maximize the chance of finding irregularities if there are any.  I've never used the bridge and don't know it's capabilities, but if you plan on buying multiples of those kilo bars, it might be worth the added expense of the bridge for greater scanning depth.

Agree, the bridge is worth the extra expense for its scanning depth.   I believe the wand has a scanning depth limitation, so you need to take that into consideration.
