Tesoro Speaker opening styles.

[Kalvin]

Hi guys, Fairly new to the forum. Been metal detecting for about 15 years. AT Gold and AT MAX.

I'm curious about the speaker openings on the Tesoro machines. If you look at the Golden uMax you see some with a louvered speaker opening and some with a rounded raised area with a grid of round holes.

Is one a newer model then the other? Produced at the same time? I've read there was a software update to change the tones on this machine at one point in production. Was the exterior case changed at the same time?

The golden uMax is not the only model I've seen with the different speaker opening. Also noticed this on a Diablo.

best regards,

The round hole style was the first one used on MicroMAX Tesoros. The louver style came later - on US models, anyway. Some non-US market Tesoros appear to have used the round hole faceplates longer.

Thank you pinenut. My machine does seem to be an old tone model which would make sense.
