The addition of a reasonably new know-how, radar, has shaken up the world of chronographs. However what of the older, optical fashions? They nonetheless work. I’ve owned not less than 4 totally different optical fashions, beginning with the previous fold-in-half-when-done Taking pictures Chrony again within the big-shoulder-pad period of the Eighties. I needed to have two of them since I shot the primary one. I then purchased Caldwell’s Ballistic Precision and Professional fashions. I even managed to shoot a kind of. I suppose I’m a greater shot than I believed – these wires and helps are tiny…
When Labradar introduced out its radar-powered mannequin, the world of consumer-owned chronographs modified. Not did you could place sky screens with their attendant wire(s) downrange and need to shoot by means of a gap. There was nothing to hit unintentionally. What an idea! They had been however one firm to make use of radar… there have been others, however these items have been pretty dear. Issues actually modified when an organization recognized for its GPS and wrist-worn devices received into the chronograph recreation. For the primary time, you might have correct velocity readings from a tiny, Go-Professional-sized three-ounce field that sat in your taking pictures bench with no wires and no peep-type-sight to goal it on the goal. That might be the brand new Garmin unit.
Garmin received into the radar chronograph enterprise a few years in the past with their model of the radar chronograph, the Xero C1 Professional. I needed to have one, and I’m glad I purchased it. It’s so small that it could possibly sit in my vary bag and go together with me to my taking pictures bench each time I do. It’s tiny and lightweight. Caldwell then received into the radar enterprise not way back. Bear in mind, they’ve made optical chronographs for years, various of which I owned. So that they weren’t new to the sport… simply the radar a part of it. After I discovered of its existence, I began bugging Jarrod at Caldwell to get one. It got here by means of final week. I’m glad my Dillon vary bag is massive sufficient to hold each chronos!
Caldwell’s model of the radar chronograph known as the Velociradar. A intelligent title, for positive! They did issues a bit in a different way than Garmin did – they used a special kind of radar know-how. Whereas the Garmin unit makes use of Doppler radar, the Velociradar makes use of Chirp radar. What’s the distinction, you ask? Properly, after speaking to firm reps I imagine it comes right down to the truth that Doppler provides you with one fundamental measurement – muzzle velocity. Chirp, then again, measures velocities a number of occasions through the course of the bullet’s flight out to a sure vary (usually 100 yards). That manner, the Velociradar can show a specialised desk in its D.O.P.E. menu selection. This desk lists bullet velocity and power for varied yardages to 100 yards. It can also determine drag on the bullet which leads to its displaying a ballistic coefficient for that individual bullet. It could actually do all this with only one shot.
Earlier than I sum up, under, my comparability between the 2 let me state that this text’s goal is just not to decide on one over the opposite. I’m merely evaluating the 2 and exhibiting their options. They every do various things very nicely… I’m glad I’ve them each. The pistol shooter in me loves the Garmin, whereas the rifle man dwelling in my home is basically stoked concerning the Caldwell. Why?
My reasoning for that’s this: should you want a fast muzzle velocity examine from a firearm, bow, BB gun, and so forth. with minimal set-up and also you don’t want 100-yard ballistics, the tiny Garmin is the one to set in your bench. But when you could know precisely what that .308 bullet is doing downrange at 100 yards – velocities, energies, bullet drop, ballistic coefficient information – activate the Velociradar. Typically I’ll set each of them up on my bench – speak about data overload! That’s an excellent factor, for shooters. Additionally, they every have a full-featured Bluetooth telephone app that makes utilizing them simpler… you will discover your self reaching in your telephone greater than you thought. There’s extra on that under.

Controls & Menus
Each items have soft-press buttons that management them.
The Garmin Xero C1 Professional has 4 buttons, throughout the highest: “OK”, Again/Energy, arrow up and arrow down. Turning it on, you will discover on the show: battery power, and three selections: New Session, Historical past, and Settings. The arrow buttons navigate these selections. Right here is the place you begin a brand new session, evaluation a saved one, or go to settings.

About
With out going all geeky on this, suffice it to say that you’ve the power to decide on rifle, pistol, bow, or air rifle… it really works with all these. As soon as rifle or pistol is chosen, you’ll be able to then select a velocity vary (for instance, rifle, 1700-5000 or 600-1700). At this level, you’ll be able to enter the bullet weight so it’s going to calculate power. The subsequent button press takes you to the taking pictures display screen… shoot your session after which, with a button press, both cancel it or finish it. When you finish it, it’s going to put it aside. The Garmin will save 50 classes internally, however I discover it simpler to maintain them on my telephone or laptop computer. That’s the gist of the Garmin.
The place To Purchase
Caldwell Velociradar
The Caldwell goes about issues a bit in a different way, as you may think. Buttons are on the entrance of the unit, surrounding the show. They embrace (left facet) cursor arrows for up, down, left, and proper, and (proper facet) energy, choose check-mark, again, and an “arm” button that you simply press to allow or disable radar throughout a string.
Whenever you flip it on, you’re met with a three-choice menu: New String, Load String, and Settings. Simply press the check-mark button to pick out new string. You’ll be able to go to Settings to enter bullet weight
The place To Purchase
Set-Up and Use
Each chronographs are designed to be positioned in your taking pictures bench or subsequent to it, on their tripods. (Some shooters like to make use of a full-size picture tripod with the Caldwell… that’s your name).
The Garmin must be 5 – 15” behind and to the facet of your muzzle, though it did work slightly additional out. You merely level the show towards you and the again of the unit towards the goal. Actual placement is just not required. After going by means of just a few button presses, you begin taking pictures and your velocities will seem. After you finish the session, a abstract comes up on the unit and in your telephone app. You’ll be able to then save the string and finish the session. After that, you’ll be able to export the info to Excel should you like.
The Caldwell is a a lot bigger, heavier unit. I personal each of those and I exploit them for various functions. The Garmin is nice for a fast velocity studying on a string of pictures. I’ve even used it to measure a granddaughter’s Pink Ryder BB gun muzzle velocity (273 fps). One factor it gained’t do, nevertheless, is chart downrange ballistics or the ballistic coefficient on a string of pictures.
The Velociradar will do these items. It is a chrono for individuals who wish to discover out what their load is doing from the beginning gate all the way in which out to wherever you positioned your goal – they suggest 100 yards. The data that it returns to you has velocities at varied ranges, energies at these ranges, and a calculated ballistic coefficient for that bullet’s string of pictures. To set it up, you set it on its tripod after which you should then align it with the goal. There’s a peepsight of types on the highest of the unit – goal it at your goal. OK, now it’s aligned, so flip it on.
You’re met with a three-item menu: New String, Load String, Settings. Use the arrow keys to navigate all menus. So far as settings go on the Caldwell, listed here are your selections:
There are few settings, however the telephone app provides some performance. Your first determination needs to be which set off you’ll use. If you’re OK with the acoustic set off – you might be taking pictures by yourself with out different shooters round you – you do nothing. That set off is the default. However, should you’re at a loud vary you’ll be able to connect, by way of velcro straps, a “change” to your rifle that plugs into the unit. You’d then set the set off to recoil within the settings. As for auto-ready, I depart that chosen because it arms the radar routinely for every shot. You’ll be able to change that if wanted.
Talking Of The Cellphone Apps…
Each apps are useful. When you join the units by way of Bluetooth, a world of knowledge is in your hand. Listed here are a few display screen pictures from each chronographs.
Garmin
These examples are of a three-shot string from my 450 Bushmaster. Left, a abstract display screen and proper, particular person pictures.
Listed here are two display screen pictures from the Caldwell telephone app…
The left shot is a string of 9mm pictures. The precise shot is the “Dope Chart” that was generated. Clearly, we wouldn’t care about 100-yard-plus ballistics with a 9mm, however with rifle cartridges, it could possibly get fascinating.
You have got choices with each apps when it comes to getting into extra data similar to gun used, climate, bullet information, or different notes. With both, you’ll be able to export your accomplished data for a string to Excel. The pc geek in me likes that… you’ll be able to maintain a document of your handloads, or manufacturing facility masses, for a sure gun.
Which One Is Higher?
HA! A trick query! They’re BOTH higher! Howso? They do various things. All the time earlier than, my chronograph expertise had me measuring muzzle velocity, interval. When radar and digital electronics hit the chronograph market, issues modified. However… I nonetheless principally measure muzzle velocity. I extrapolate data from that studying and might decide, roughly, downrange velocities and energies and trajectory. That’s been my mindset. By the use of rationalization, I’ve just about spent most of my taking pictures years with a handgun of types. It’s solely been lately that rifles have gained numbers in my gun secure. So, I by no means had the necessity for downrange ballistics such as you rifle shooters on the market want. However, like I mentioned, that’s altering. Muzzle velocity is only one factor that may be measured now.
The Velociradar (and Labradar earlier than it) permits all that “new measurement.” Now, not solely are you able to measure muzzle velocity, however you may also get downrange velocities, energies, and even a ballistic coefficient because the radar can measure drag on the bullet. The reloader in me is pleased. Now, we’re speaking!
So, Which One Do I Purchase?
So, which do you have to purchase? They every have their pluses. The Garmin suits in a pocket, is extraordinarily correct and is IPV7 waterproof so you’ll be able to shoot within the rain, if that’s your factor. The Caldwell is bigger and heavier, and it’ll measure issues the Garmin can’t – they name it their D.O.P.E. chart. I discussed them above. Plus, the Caldwell means that you can use an acoustic or wired recoil set off. The ball head on the included tripod means that you can at all times have the chrono perpendicular to your bench. However, you must bodily goal it at your goal, one thing the Garmin doesn’t require.
Reducing to the chase, the Caldwell will do every part the Garmin will do, however it’s bigger, heavier, and must be aimed on the goal. It’s indispensable, although, in case you are a rifle shooter who wants downrange ballistic data. A pistol shooter who by no means shoots past, say, 50 yards can be nicely served with the Garmin. Its pluses are its tiny dimension/weight, and its freedom of place in your taking pictures bench.
The place pricing is worried, I’ve seen the Garmin for as little as $411, whereas I’ve seen the Caldwell’s pricing hovering round $499. (That $411 value is abnormally low, though it appears legit…). You’ll be able to, for essentially the most half, anticipate to pay round $50 lower than MSRP for both one at some mainstream websites.
As I mentioned above, I’m glad I personal each – they every do various things nicely. As for you, you could resolve which of the 2 will fill your specific want the perfect. That’s a name I can’t make.
