I have been spending some time experimenting with my Safari ...Another forum member gave me a list of things to try using my Safari and I was really quite surprised at what I heard ....One of the biggest revelations and there were many , was the fact that the " Mastering the Quattro " book mentioned using the "Low Trash Density " as the norm as it gave slightly better depth, and also better target I.D. ..... What I found ( thanks to my forum friend ) is that by using the "LOW" setting , the recovery time when going over a target is VERY slow , and in most cases whatever the first target that you hit , is the one that you are hearing and other targets just get smeared into that one tone with the recovery being so slow .....In other words there are other targets that are missed ..... Slowing down helps, but is not the cure all .....I found that when using the "High" setting as mentioned in the book for sites with more trash , that responce time is much faster, and you can hear the target seperation BETTER than with the "Low " setting .... I"m not sure how much depth I'm giving away , but I'm surely finding a lot more targets , and much more clearly , running the "High" setting .....The seperation of targets is almost like putting a small coil on your Safari .... It also pinpoints just fine ..... As far as the target I.D. , I go more by the tone than I do looking at any target I.D. numbers ....I'm not sure that there is really ANY machine that has accurate TID's .....I won't even discuss the icons that pop onto the screen ..... While the book recomends using the "Low" setting as the norm, and use the "High" as a specialty setting , I'm not so sure that I will use the "Low" setting unless I go beach hunting as a "specialty" setting .... ..... I'm also catching more flies with a much lower sensitivity setting too running this way , but thats another story ....Jim
