Minelab GPS For CTX And GPZ With Notes On XChange2

[Steve Herschbach]

The first of a series of articles I am doing about the GPS system that comes with the Minelab CTX 3030 and GPZ 7000 has been posted on Minelab's Treasure Talk site

Thanks! Next in series already written, should be three more after that, for five total in the series.

Steve, I haven't read article #2, and maybe you address it there or will, but how well does the GPS work under the canopy of pine trees like in the Sierras?  I use a Garmin Etrex with a high sensitivity antenna to mark my spots, reception is slow but fairly accurate.  I don't own a GPZ, but I hope to someday soon :)

Thanks,

Brian.

Article 2 has not been posted yet. GPS unfortunately relies on satellite reception. My experience is that with multiple satellites in view reception under a tree canopy is pretty decent, but if relying on marginal satellite views gaps can and will show up. What happened when a track is being recorded is that a gap in reception shows up as a straight line between the last point with good reception and the new location where reception gets picked up again.

Your mileage may vary.

I found several places last week where the gpz lost gps....all under big pine trees.

I look forward to reading the series...always worth the time!
