Saw a possible speed trap Saturday evening

[Dave R]

Heading south between Bear Island and Meredith Neck, there was an MP boat that appeared to be tied to a dock near Horse Island. He had a clear view up the passage and had no lights on. This was around 9 PM. There was plenty of light (obviously, or I never would have noticed the unlit MP boat), but it was about 40 minutes after sunset so the 30 MPH limit was in effect. That's a great spot/time to generate a little revenue.

The lake was really dead Saturday, wonder if he nabbed anyone...

At any time, do you think you're on the right side of the law in disclosing a law enforcement officer's location?

...BUI hunting...me likey...thanks Dave for this helpful post after the fact...no sense giving out the strategies of the constables to the offenders' he's hunting...btw...if that's the cop I think it was, he's a good guy with a tough job......

Show us where it is illegal.

He can't because it is not.

In actuality in many cases it is of benefit for the general public to know, or at least expect, law enforcement presence in a particular area.

Finally anyone with a smartphone is already aware that there are a number of fairly accurate Apps that relay this information in realtime.

Much ado about nothing.....

What there no law against disclosing the location of a law enforcement officer? SB6789 (No disclosing the location of a law enforement officer), we will get this on going as soon as possible. Right after bad hair and no forums in NH.

Could be a patrol officer either lives there and took his boat home (I've seen plenty of state and sheriff's do that with their cruisers) or could have been over there on a call, not necessarily sitting waiting to bust somebody. Either way, I have no problem with the MP using whatever tactics they need to to catch the bad guys out there. I've always thought they should ditch the marked boats for unmarked ones anyways. Way I look at it, if your out there and doing nothing wrong no need to be concerned one bit at the presence of the MP. Give 'em a wave, they got a tough job out there.

We're the creativity? Perhaps there is a scandal afoot and it's a MP officer having an affair with one of the people at that house.

I've only been on the water twice thus far this year. Spent all my time from Alton, Gilford, and W-boro areas and never picked up the MP on my radar detector. I haven't checked but I assume they will use the same Ka band as the State Police.

Given so few boats are doing over 45 MPH I seriously doubt a MP officer would set-up on stationary radar for any length of time. The most likely time to get someone is the gray area when the sun is dropping and sunset is reached but there is still a lot of daylight.

For those who travel along Rt 11 from the Spaulding, not sure what town it is but they have a D.A.R.E schemed car and he lines himself up to clock you at over 1/2 mile until you see him. I was picking him up over a mile out with my radar detector It was right around where the speed drops for 55 to either 45 or 40 MPH. Classic speed trap.

The revenue enforcers are out there but much more likely to get you on the road than on the water.....

Yup, every time. It's not like I lied or violated a non-disclosure agreement.

Would you rather have people speeding and getting caught, or not speeding at all?

I'd rather see the MP looking for drunks than setting up speed traps. Anything people can do to make speed traps irrelevant is a step in the right direction.

Just so it's clear, I'm OK with a 30 MPH speed limit at night. Seems like a reasonable and prudent practice and one I practiced most of the time prior to the limit.

My understanding is that they are primarlily using a handheld LIDAR unit, not the typical Ka band radar SP and many locals use, although NHSP is quickly equipping many Troopers with handheld LIDAR units as well.

The LIDAR units will require that your detector have that ability to detect same as well as the typical Ka band requirements. And while the Ka band disperses with range and is fairly easy to detect with a decent detector, LIDAR units, by the nature of their concentrated and mostly non-scatter light beam, are much more difficult to detect in an omni direction as would be required on the water.

Just some food for thought.....

LIDAR would be preferable on the water because it's really good at resolving specific targets, but one would need a pretty steady hand to get a reading. Tied to a dock would be ideal. I can't imagine they'll have too many LIDAR traps out in the choppy broads...

Since LIDAR computes the target speed based on how far the target has traveled relative to the LIDAR unit (in a given time), it suffers the same problem as speed radar in that it's only accurate when the the target is going directly toward or directly away from the LIDAR. Any deviation from a direct tragectory will yield a lower speed reading. That said, It's a function of the cosine of the angle, so even if the target is 20 degrees off a direct path, LIDAR will read only 6% low.

They use the Prolaser III.




ProLaser III Operator's Manual

The technology used by the ProLaser III to measure
distances and speeds is referred to as lidar, which stands
for light detection and ranging. When the trigger is pulled,
the ProLaser III sends out hundreds of invisible infrared
laser light pulses per second. As each pulse is
transmitted, a timer is started, and when the energy of a
laser pulse is reflected from a target and received by the
ProLaser III, the timer is stopped. From the elapsed time
taken for the laser pulse to strike and return from the
target, the distance to the object is calculated with the
known speed of light through the atmosphere. If the
target is moving with respect to the ProLaser III, a
sophisticated algorithm is used to derive the speed of the
target from a successive number of range calculations.
This speed determination is then displayed to the
operator.

My RD will sniff out the PLIII as well.

For those interested, IMO the Escort 8500 is the best "bang for the buck" detector on the market. This is what I have on the boat. The 8500 can also mate up to their lasar jammers albeit the mounting would have to be figured out but not that hard to do.

You would be amazed at how often your vehicle gets painted with police radar on the road.

It's funny. There's a vastly superior tool than LIDAR for measuring the speed of multiple boats, simultaneously, and on any heading, right in that photo.

Ask any engineer at the Raymarine Merrimack R&D plant. A marine radar with the right microprocessor can determine the speed of multiple boats very accurately. As DR points out, the LIDAR is not accurate on water.

I saw a number of state troopers on 106 standing outside their cars aiming at cars with what looks like a miniature vdeo camera. It is definitely not a radar detector. Can Skip tell us what it might be?

It's a handheld instant-on LIDAR (or Laser if you prefer) unit. Unlike the traditional Ka band units installed in their cruisers, using the device you saw with its integral aiming allows Troopers to "paint" and pick out individual vehicles, even in moderate traffic, from very great distances. The NHMP unit pictured above is just a slightly different version of what NHSP is now using on the highways, along with a growing number of local & county departments.

My cousin is a chief of police. One of my best friend is a captain of a large city police department. A third is the sheriff of a Mass. County. I'm in good hands!

On this lake—given its darkest hours of history—I'd want both.

Ouch, wonder what happens to your automobile insurance bill after four motorboat speeding violations go on your driving record? Most likely, the "good hands insurance company" will not cover you anymore and they say to you "goodbye & have a nice day!"

There are not many on the lake that big...A couple at most. Is that the red Skater? What an impressive boat to watch. We heard it coming around the corner a few weeks ago, it sounded like a helicopter coming in at low altitude and was throwing a monster roost even though he was doing aboout 40mph.

Must be either a total moron at the helm, multiple operators of the same boat, or a helmsman who is immune to traffic tickets.

If one has no operator's license, is there much that can be done (beyond constant fines) to a habitual Winnipesuakee speed limit offender?

Four times is a bit much, and I doubt he was doing 50 or 55 the first couple of times. It's pretty obvious from the statistics that there aren't many cowboys out there. The MP, widely derided during their testing period by SL proponents, was spot-on accurate in their assessment. My guess is that if the daytime SL was 55, that one 50' operator would account for 75% of all tickets.

I realize that in any activity, there are those that push the envelope and beyond. Some of them are prudent and safety-conscious, some are just wild and need to be reigned in. The vast majority of issues reflect the total disregard for the safe passage rule.

Steve, I hope you did not take the bait and sign onto the parasite forum.

If you did, I will tell you then my guess is that is where someone tracked you down as have you likely given them your email address. An a non-NH IP address from Vt (or ME), it sticks out like a sore thumb when you post....... Hint: You can easily hide and change it if you feel you need too.

It's extremely taboo for forum owners to reveal or use the info they have given them by users and discuss or reveal to other users.

It would scare you to know what you can find with peoples IP and email addresses if someone has sinister intent.....
