You can make a probe if you have a welder and the know how.
1" pipe by 12" long. Useing a 5/16" or 3/8" drill bit drill a hole through the center of the side (6" mark).
4'-6' long By 5/16" or 3/8" thick springsteel rod. Place one end of the 5/16" or 3/8" springsteel rod through the center of the 5/16" or 3/8" hole on the 1" pipe untill its flush with the other side of the 1" pipe. Weld the 2 pices in place.
Now on the other end of the 5/16" or 3/8" springsteel place a nut about 1' to 1 1/2" up the shaft. Weld only the bottom side (ground side) of the nut to the shaft. grind off the rough weld on the bottom of the nut to a simi-long tapper. Then grind the tip to a pointed tapper.
Note: If your hardwear/steel supply store doesn't carry springsteel then the next best thing to use would be coldroll.
