looking for second hand device, preferably whites tm 808, as recommended by fellow hunter (should I acknowledge you by giving your name ?), for locating tunnels, cavities, blocked entrance.

any other suggestions ?.

I'm south of texas-mexico border close to the coast.

any idea successfully leading to the finding of the main blocked entrance will be very well remunerated: honest.

you bet that we will all hear about it in the news !.
