Was wonderin if anybody has used one, whats the depth ?? can it punch the signal through the grass ? and if so , to how deep? How does it affect battery life on your machine? I'd be putting it on my MXT. I've been using a bullseye and it seems to be weak, an inch or two is max. I'm thinkin the sunray would be better, cause I'm kinda gettin to like the pinpointer, when it saves ya from diggin a plug, most of the time I can pop out the shallow coins (up to 2 1/2" deep) any comments/info appreciated, also the list price is like $179, wheres the hottest deal/ best price, on one right now?? thanks, Rich.
