Officer Hubb’s Review of “TresMon’s Long Range Shooting Clinic.”

13 FEBRUARY 2011

First allow me give some background on myself. I have been in law enforcement for about 13 years. Those of you that have attended a LEO type course/school will understand this critique. I am an active duty FBI trained sniper on my local LE department SWAT team. I am the lead firearm instructor as well for our department.

It has been my experience that Law Enforcement officers use schools as a semivacation paid by their agency. At shooting classes/schools you’ll find a room full of (type A) students. Allow me to say I am not necessarily “that guy”. When we get to class we posture, size up the competition and get ready for the dreaded classroom portion of the school. When the course/school has anything to do with firearms, all we can think of is getting some trigger time. Being professionals we endure the lectures and take the written test. Obviously, this is not the most productive attitude to have when it comes to learning the finer points of long range shooting.

So to break tradition, I went to a “civilian” school that just concentrated on the classroom portion of long range shooting.

Course Title: TresMon’s Long Range Shooting /8hrs
Date: 02/06/2011
Location: Bass Pro Shop, Sevierville TN
Instructor: Tres MonCeret “TresMon”
Price: $85; Local (to E. TN), Preregistered

Instructor Bio: Tres is a frequent contributor to the Sniper’s Hide and other forums. Just do a search and you’ll find he has several great posts. He previously joined the Marine Corps and is a very avid tactical shooter, so he is not a “civilian” by any means. Tres is a machinist by trade and a Christian by heart.

Class Critique:As you can see from the topics listed this is a very comprehensive clinic. The students who attended this school were either hunters or long range competitors. There was a no kidding a “nuclear engineer” in the class so the math conversations took on a whole new level of explanations. To my knowledge I was the only LEO in the class. Tres, although not an artist used a dry erase board to draw diagrams that explained the concepts he was teaching in such a way that “I got it” for the first time. Some of the topics he covered I had heard of though I did not completely understand until now.

I have read a ton of books and manuals on sniping. I have been through the FBI Sniper/ Observer course. I have never read or heard of some of the information I got from Tres’ class nor had it put in such an easy to understand way before.

Tres has a strong confident voice that made the lectures easy to listen to. Tres took the time to look at the students faces to see if they comprehended what he was explaining. He fielded every question put to him and would not move on until the student got the concept. What I find that is so unique about Tres is that he can explain very technical, precise concepts in almost layman terms.

The subject content was very well presented. Tres gave a disclaimer up front that this is the first class he has taught in the classroom environment, rather than on the firing line. I could not tell. He was well prepared- He scouted the conference room before hand, ran several different lesson plan schedules and had made back up plans incase of technical difficulties. He used scenarios that were sometimes in hunting language, competition language and sometimes in sniper lingo so everyone could understand what he was saying.

In conclusion, Tres has an extraordinary ability to explain the mysterious science of long range shooting. If you need to understand all of the factors that effect shooting from 400 to 1400+ yards this is the class for you. I think this guy will be one of the names you will hear in the future as an instructor that is a must to train with.
