The time Ranger any day, and here's why.
There are 4 versions of it, the last one was the only one with a prospecting mode. Still sold new as "Titan 9000".
The original Time Rangers (first three versions) had an ID scale ranging from 1 to 299.
When the V4 was released, they cut it to 1 to 199. In doing this, there is an interesting side-effect for gold ring hunters : about 99% of ALL pulltabs in the creation will register Under 5c. NOT Under pulltabs. Yes, even the beavertails will be found in the 5c range, and yes, you can differentiate them from nickels.
Now, every signal in the pulltab range becomes highly suspect for those who hunt for gold rings.
The Time Ranger/Titan 9000 gives accurate ID up to 6-7".
A very good unit for the price, even if it is now outclassed by newer FT releases.
