I went from the MXT (expert with about 300 hours), to the V3 (with about 100 Hours, and HATED IT), now I have an E-Trac and love it with about 300 hours. When the machine is set up right, with the right type of pattern, you can swing pretty fast... Faster than an MXT. The E-Trac's processor is VERY fast, it's just a matter of training your ear to the different tones, and investigate all tones that can be a coin. I know a silver target the first time I hear the tone. I'm still averaging 4-5 silvers a day with a fast swing speed at the same old three parks I've been hunting for years.
So, a few tips about the E-Trac out of the box to a newbie:
1. Read the book everybody is suggesting.
2. The default program is for ALL coins, not just the US. Get yourself a good US pattern. PM me for one if you like.
3. Start out slow until you train your ear to hear those tones that are desirable. It will take about 100 hours until you become one with your E-Trac. Silver sounds like angles singing... I mean like brakes squeaking...
4. Dig all deep penny targets, sometimes they can be silver.
5. Hit the trashy areas. I go where I was afraid to go with my MXT. the E-Trac is so fast, it will separate the trash signals and alert on the good ones, even if the targets are in the same hole.
6. Once you clean out an area with the stock coil, go get the SEF 6x8, or the Minelab 8" FSB and proceed to clean it out again.
Everything else you either have to learn from a veteran, or hunt a lot and learn it on your own. Good luck, and happy hunting!
