I have both the old and new style Bullseye. While they both work well, I found the detection depth too limited. So, I upgraded to the Garret ProPointer. It has sped up my target retrieval immensely. Surprising what a couple of extra inches can do (approx 1 1/2" on a dime and close to 2 1/2"+ on a quarter)
Now on shallow targets, I use the pinpointer to scan the ground first, and if the target is within 2-3", I can zero in and just make a small slit and pop the coin out. Or easily find the little bits of foil, bb's, pencil erasor caps, jean rivets with ease.
With deeper targets, it sure helps to know when getting close so you don't accidentally scar the target with your digger, allows me to dig smaller plugs in manicured lawns and parks.
Now thinking back, I should have purchased a DX-1 with my MXT, but at the time thought that I might switch machines more often, and could use the Propointer with either one, as I have an IDX that I was going to set up for quick tot lot hunts.
The Pistol Probe came out afterwards, and it sure gets a lot of depth, but up here in
Canada where handguns aren't allowed, I think it would cause too many suspicious looks. One of the spots I hunt is just across the street from the Police Station.
