<img src="/metal/html/yo.gif" border=0 width=31 height=15 alt=":yo"> I havent seen this one but I have seen the 2 12 inches around one that I feel is too small even with the periscope pinpointer (possable damage to target as well as too small of a hole to get your hand into). I did some tinkering with different size tubeing and came up with 3 inches as the ideal size. 4 inches around IMO is too big and requires a great deal of enegery to plant in the ground (and I'm a muscular guy...BTW..."I did not grope that girl" cal governer!!!) <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol"> Also as for depth, the ideal depth is aprox 5 or 6 inches depending on soil type as friction will preclude you from removing the plug from the plugger. IN my opinion, pluggers should be required as they make the finished product look much better the even the most miticulus digger out there (FACT). We just lost our very old central park (schenectady) due to sloppy digging by lazy hunters. Also, It blows my mind to see detectorists digging on a lawn without a cloth or something to put the dirt on, or hunters on the beach with no garbage container (nail pouch)...like there so good that they never dig a bad target. Oh yea, for the anal retentive guys that say" what about the north south orentation of the plug..the grass will do better if its returned to the same posistion" Place a golf tee with an arrow in the plug before you dig!! <img src="/metal/html/yo.gif" border=0 width=31 height=15 alt=":yo"> <img src="/metal/html/yo.gif" border=0 width=31 height=15 alt=":yo">
