No need to spend big $$$$.. Instead of paying $$$ for a fancy digger, I went to
Home Depot and bought a gardening shovel for about $5-6 or so.. It's one
piece and will never break, unlike the one I got with the machine. It's puny
stem broke after about 3 hours of use..
You'll never break that orange handled job..
But I actually rarely use that. 98% of the time I use just the blue handled
screwdriver probe. It's a Home Depot screwdriver that I ground the tip down
and polished up to be smooth. That way it doesn't scratch coins much.
The pushrod is a backup probe, and what I used before I made the blue one.
The wood shovel I rarely use, but keep it for grins in case of a deep hole.
It's stem is not too strong, and it won't take much abuse..
But it was only one dollar at the dollar store, so what the heck.. :/
Also have the machete in case of thick vines, brush or what not.
Could also take the head off a snake in a pinch, but it's not too long for
that type of use.. A large snake could bite that far..

I do less lawn damage using the probe vs the digger.. I'll only whip the
digger out if something is really deep or large.
It does have a handy ruler on it for measuring depth..
