These items normally require Identification (Passport) or a Firearms / Shotgun Certificate before they are handed over. Shotguns, Rifles, Airguns and Moderators are usually good examples. When purchasing a 'collection only' item you are in effect paying a deposit for your goods. In all instances you can choose to collect your item from one of our stores (Exeter, Dorset or Newport) or from a 3rd party gun dealer. The latter may be at an additional cost to yourself. Turn the unit on by selecting feet per second (FPS) or meters per second (MPS) with the power switch AS WITH ANY ELECTRONIC DEVICE, WATER CAN DAMAGE CERTAIN COMPONENTS. TO PREVENT DAMAGE, DO NOT USE CHRONOGRAPH OUTSIDE WHEN IT IS RAINING WITHOUT BEING PROTECTED. SPECIFICATIONS

Remove Sun Shades in heavy overcast or shaded conditions. The Sun Shades are only necessary in sunny or partly cloudy conditions, and by removing them in other conditions you'll allow more light into the chronograph. finally, 5) extreme spread is not statistical nomenclature. The real definition here is called “range” in statistics. It is simply the range from low to high of a data set. It is a primary measure of variation of data while standard deviation is a very particular statistical calculation of variation. Any cheap calculator (spreadsheets) have this function available and can be used easily. First one usually calculates the average(statistical jargon is “mean”), then the sd using a particular number of datums. Use at least 3 data for each assessment. 5 or 10 of course are better. How a shooting chronograph actually works depends on the exact type you get. Right now, there are three general styles. Skybox Chronographs With the LabRadar, you get a string of data per shot, 5 user pre-set distances out to 99 yards. So you get much more information than just the muzzle velocity. Loading for multiple rifle and pistol calibers, the LabRadar allows me to get into the nitty gritty of fine tuning my reloads. The sunshades are extra wide for better reliability on sunny days and are constructed of a durable synthetic material.Caldwell Ballistic Precision Chronograph Premium Kit Contains everything you need to capture reliable velocity data in one convenient kit. Includes Chronograph, IR LED Light Kit, Tripod and Custom Carry Case that conveniently holds all items. The Caldwell Ballistic Precision Chronograph Premium Kit provides accurate velocity measurements across a wide range of shooting conditions. Higher accuracy was achieved by using a high speed 48 MHz processor and by designing a circuit with an advanced data interface that allows each unit to be computer calibrated at the factory after assembly. The end result is the ability to provide much better accuracy than other chronographs on the market (+/- .25%). Although technologically advanced, the unit is designed to be simple to operate, displaying velocity in Feet per second or Meters per second on the large built in LCD screen. IF YOU ARE NOT FAMILIAR WITH APPLICABLE RULES FOR YOUR APPLICATION CONSULT THE MANUFACTURER(S) OF THE FIREARM, AIRGUN, PAINTBALL GUN, BOW OR RELOADING EQUIPMENT/COMPONENT...

As a set of batteries loses power the red LEDs may still be partially visible even though the IR LEDs are not putting out an optimal level of light. If you notice errors or inconsistent readings, switch to 110 power or replace the batteries. I would only recommend the Labradar to users who really want the very best information and are willing to spend the time and effort in setting up and learning the system.

Long-range shooter enthusiasts, you might want to read this one out. The Beta Master is one of the best long-range shooting chronographs in the market right now. It has some downsides though. This is the cheapest type of chrono for a reason. Mostly, it’s not super accurate over the long term. Clean Lenses. Remove build-up of dust on the sensors. Use a Q-tip or canned air to clean the lenses, being especially careful not to scratch them. While the Labradar is considered to be the cream of the crop in chronographs, I really didn’t have a good experience with it.This unit can perform a lot of actions, one of which includes its string shot memory. The Beta Master can store up to 60 shots in its internal memory. Like the ProChrono, you can delete an individual or a whole set of string shot data.

The Caldwell chronograph is a simple light sensor design that does what you need it to do and nothing else. It’s lightweight, easy to set up, and really has nothing you can screw up.

For best performance - make sure your device is up to date with the latest software updates provided by your manufacturer and/or carrier. Avoid low light conditions, such sunrise and sunset. During these times the extreme low angle of the sun can cause added variation due to reflections and low levels of light. Use of optional light kit will improve function in these conditions. The list goes on. But basically, it’s an advanced user kind of thing. But don’t let that scare you — they’re actually easier to get into than you might think. Best Shooting Chronograph

Place Chronograph on stable surface at the appropriate height for firing projectile through the shooting window. The Chronograph may be mounted on top of a Tripod using the ¼-20 threaded insert. For me in the desert of California where it is as cloudless and bright as the dark side of the sun 99 times out of 100 that I go out — I never really had much of a problem.DO NOT TRY TO PROTECT YOUR CHRONOGRAPH WITH ARMOR PLATING. BULLET RICOCHET FROM HITTING THIS PLATING COULD CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH. CHRONOGRAPH COMPONENTS ARE REPLACEABLE. By default, a chronograph’s main goal is to measure time. This is also true for shooting chronographs. The entry-level or casual tier Magnetrospeed, the Sporter model is perfect for hunters, casual reloaders, or people just starting out. If you are unable to connect your Android device to the chronometer follow these instructions:
With the audio cable disconnected at both ends…
1. Connect the audio cable to the Android device
2. Connect the audio cable to the Chronometer
