Bought my first pulse detector-Surfmaster PI Pro

[Sven]

I got a good buy on a used Surfmaster PI Pro.
As a beginner using a PI unit as the this, any tips you can pass along?
Thanks

About the best i can do is recomend you pass the coil in all directions and listen for the double blip of boobies, passes not too short as the SAT may tune the target out. all doble blips are not booby pins or nails etc but the majority are.(they don't all give the doble, depends on the way they are laying)
To start with dig them all to get confidence in whats what
short and smooth usually good, big and scratchy, usually rubbish
You'll get the hang of it, good luck

Thanks,

Just repairing the coils tip where it has been worn down and will be painting the coil yellow-too hard to see when the bottom is stirred up.
Will need to add some weight to the coil as it's a floater. Only thing holding me back right now is I need a clevis that holds the coil to the lower rod.
I have to buy the entire lower rod....shipping to Canada from the US will put me back $40.00 US before the customs sock me with fees and sales taxes.
I can order from a local dealer still cost me about $32CA shipped. I just want the clevis, don't need the entire lower rod.

So I have figured out a way to make one using common household tools and off the shelf parts from the hardware store for about $5.00.
Will post my project when finished.
Wish I still had my small lathe and milling machine, I would just machine one out of a block Delrin.

you could drill out both ends and join with a wood dowel rod also gluing the break with epoxy, the dowel will give a little bit of strength, bit like a bone

Thought about that but the clevis has become brittle and is crumbles.
I did have to drill the broken portion out of the lower rod.
Even with a special drill bit made for drilling plastic the stem was chipping apart.

Figured rather than wasting time fixing it, make one. Shouldn't take long.

I was lucky when my old excalibur one broke as i had a small dive shaft brand new, i just knocked out the insert and put in the short dive shaft one. still managed to fix the old one with the dowel method though how strong it is i havn't needed to try it.
