Well, if have limited ped & you just want to try your luck?
I'd suggest getting lowest level crafted enmatter tools, simply because the are availbale cheaply & you can still use them they beaten up .
So for as low say 6ped you should be able to get a MF101 (finder) & MD101(driller) ( both full TT are about 10ped) .
They don't have any SIB (skill increase bonus) like the TT version ,but you are hoping to hit something with first few probes & may not try again.
If you have problem buying them , pm me I'm sure I have some storage
