Narrative:

I departed 47N (central jersey regional) at XA30L in an intro flight lesson to a prospective student in a C172SP in a northwest heading. We cleared the area while in the climb by making left and right 90 degree turns. I was searching for traffic as we begun to level off at 2800 ft when I spotted a cpr jet to my left side (10-11 O'clock position) at about 3-5 mi away horizontally and about 500 ft higher and closing in. I immediately began evasive action by descending and turning to my right. I noticed that the jet was continuing to approach us and was now descending and approaching rapidly. I got very nervous -- I thought I was going to collide with this cpr jet. I quickly level off and turn in the opposite direction (left) to maintain visual with the jet. At this time; the jet took evasive action and aggressively turned to his left and appeared to be climbing when it passed near us. In my opinion; the jet came as close as 500 ft horizontally and perhaps 500 ft vertically. I quickly recycled my transponder; tuned in 121.5 and monitored 127.6 (ewr approach frequency) to report the near midair collision. But 127.6 was very busy and I did not want to step-in in anyone else's clearance. The remainder of the flight continued without incident.

Title: C172 PLT HAS CLOSE ENCOUNTER WITH A CPR JET DURING CLB TO CRUISE VICINITY OF SBJ VOR.

Narrative: I DEPARTED 47N (CENTRAL JERSEY REGIONAL) AT XA30L IN AN INTRO FLT LESSON TO A PROSPECTIVE STUDENT IN A C172SP IN A NW HDG. WE CLRED THE AREA WHILE IN THE CLB BY MAKING L AND R 90 DEG TURNS. I WAS SEARCHING FOR TFC AS WE BEGUN TO LEVEL OFF AT 2800 FT WHEN I SPOTTED A CPR JET TO MY L SIDE (10-11 O'CLOCK POS) AT ABOUT 3-5 MI AWAY HORIZONTALLY AND ABOUT 500 FT HIGHER AND CLOSING IN. I IMMEDIATELY BEGAN EVASIVE ACTION BY DSNDING AND TURNING TO MY R. I NOTICED THAT THE JET WAS CONTINUING TO APCH US AND WAS NOW DSNDING AND APCHING RAPIDLY. I GOT VERY NERVOUS -- I THOUGHT I WAS GOING TO COLLIDE WITH THIS CPR JET. I QUICKLY LEVEL OFF AND TURN IN THE OPPOSITE DIRECTION (L) TO MAINTAIN VISUAL WITH THE JET. AT THIS TIME; THE JET TOOK EVASIVE ACTION AND AGGRESSIVELY TURNED TO HIS L AND APPEARED TO BE CLBING WHEN IT PASSED NEAR US. IN MY OPINION; THE JET CAME AS CLOSE AS 500 FT HORIZONTALLY AND PERHAPS 500 FT VERTICALLY. I QUICKLY RECYCLED MY XPONDER; TUNED IN 121.5 AND MONITORED 127.6 (EWR APCH FREQ) TO RPT THE NMAC. BUT 127.6 WAS VERY BUSY AND I DID NOT WANT TO STEP-IN IN ANYONE ELSE'S CLRNC. THE REMAINDER OF THE FLT CONTINUED WITHOUT INCIDENT.
