Any Luck with Bluetooth?

Has anyone had success with Bluetooth earphones?

I tried some with two detectors: Garrett GTI2500, and Teknetics Omega 8000.

I connected a miniature Bluetooth transmitter to the detector's earphones socket. The Bluetooth headphones linked to it perfectly.

The problem is the Bluetooth time "latency" -- the time delay until the sound is heard in the headphones.

The delay wouldn't be a problem, if just listening to some music. It's a big problem for detecting.

When swinging the coil, the sounds you hear are not close to the coil's position. The sound comes after about a half-second delay. The coil has already moved away from that spot.

- - -

Here's an example.

Suppose your coil sweep is about four feet wide, with about two seconds of time from end to end.

If there's a target in the sweep, the delay makes the sound come at about 8 inches to each side of the target.

... Swinging to the right, the sound comes about 8 inches to the right of the target.

... Sweeping back to the left, the sound is about 8 inches to the left of the target.

The only way to find the target's actual position is to sweep very slowly -- at about one foot per second. Even then, going back and forth, the sound comes at two different positions several inches apart. (And also the slow sweep speed affects the way the detector works.)

If there's also trash around the target, then you get multiple sounds at different spots, that change position when you're swinging to the right or to the left.

I found it unusable.

It's just very slow and tedious to sort out the sounds, and to figure out where they're coming from.

Pinpointing is OK, because you're sweeping very slowly anyway.

Instead of Bluetooth, I could try an FM wireless radio setup, but the Omega doesn't like the RFI. The GTI seems OK with it.

Has anyone had success with Bluetooth?

Many thanks for ideas.

I've tried a number of different setups, but none of them have worked well with my Omega. TDK 700's, Auvio earbuds, Avantree Saturns...... all were too laggy. Rapoo 3070's..... no lag but horrible sound, even with an in-line volume control. A couple of FM units..... no lag, but bad sound, along with EMI from the transmitting unit. In defense of the Rapoo's however, they did sound good on a Deus and an Etrac, but bad on my Fisher-Tek machines. Waiting to hear what people have to say about the Garrett z link. Looks like lag should not be an issue, I but need to hear that they sound decent on FT machines before I invest anymore $$ on wireless.

I'll be getting the Garrett as well. Up to 30 hrs per charge makes it worth the price.
