Just bought and it came with two coils that state waterproof. Does anyone know how deep they will go?

The S63TR went down about 6" for coins, a little over a foot for a boat anchor. . Frank

Thanks. Will probably just mainly use it on gravel bars in the Columbia river...

Yikes, that's an oldie. Hope you didn't pay much for it. In it's day, it was a decent machine but there are a ton of better detectors these days.

Only paid hundred bucks. Mainly just got it for the vintage. Also have a Whites classic III, buying a Minelab Eureka gold next week. Still doing alot of map plotting to find some descent places to go in eastern Washington...

The 66tr was my first machine as a pimple faced jr. high kid in those days. Re.: Frankn's 6 inch answer. Yes, perhaps it could get a coin that deep, but ......... that was the max limit. Realistically 4 or 5" on a good day. But if you had it dialed in tight, and were listening for whispers, yes up to 6". But it has no form of disc. (other than the inherent ability to null over small iron and individual nails), and would do poorly in mineralized and/or un-even ground.

For vintage, sure, they're a cool-looking "buck rogers" type machine to have in a collection. But for actual usage, they're a dinasour. And for $100, you probably could have got any number of modern used units that would do better. JMHO. Oh, and as an all-metal TR, they also had the innate ability to see through small iron. So technically speaking, that would make them a good ghost town machine (assuming the coins weren't too deep). But to be honest with you, there were other TR all-metal machines of that era (namely the Compass 77b) that would do the same thing, and do it much better and smoother, in my opinion. Both were susceptible to larger iron (RR spikes, cast iron fragments, etc..) yet would null and see through small iron, like individual nails. Other than that, they're complete dinasours.
