Hi Mick, it deserved a good report,I was very much taken with it's abilities and enjoyed using it; hopefully I can test the Gmaxx later this year and see how that performs. I wouldn't consider either one as a back-up for the GoldMaxx though, more as a "sweeper upper" on a site after using the Goldmaxx first and then obviously in their own right on what little pasture land I have and also the more "quieter"of my sites. The only back up for the GoldMaxx is another Goldmaxx, because no matter what you use, you will always be thinking that the Goldmaxx would be doing a better job. John
