DNT TheOne 7-35×56 Review — Would Make an Excellent Telescope
Should you buy a DNT TheOne 7-35×56? Probably not. At 35X the exit pupil is 1.6mm, narrower than the human pupil in daylight, and mirage degrades the image before the glass does. 7X is too much magnification for NRL22 and for close PRS targets. What’s left weighs nearly three pounds.
What is the Best Scope for Hunting? (And Why Almost Everyone Chooses Wrong)
What is the best scope for hunting? For nearly every big game hunter, a 1-6X or 1-8X LPVO — and if your first reaction is “I need more magnification,” this article is written for you. Independent data sets put the average big game shot at roughly 130-145 yards, nearly half are taken inside 100, most cartridges hit their ethical ceiling around 400, and every bit of extra magnification costs you field-of-view exactly when you need it most.
7 Reasons To Avoid the Vortex Impact 4000 (And Better Options to Consider)
Should you buy a Vortex Impact 4000? Probably not. The Impact 4000 has excessive beam divergence, a Bluetooth remote that drains batteries or makes you wait to re-pair, a battery and display that can fail in the cold, a compass calibration many owners can’t complete, a night display you can’t dim and weaker ballistic software.
What is the best WMLRF?
Tango Fire 4000 or Vortex Impact 4000? We judged both on beam divergence, real-world range, wired or Bluetooth remote, ballistic software, cold-weather reliability, support and cost, and list the pros and cons of each. Then there’s the third option most buyers never consider.
Tango Fire 4000 vs Sightlok RF-1
Tango Fire 4000 or a Sightlok RF-1 with a handheld rangefinder? We judged both on eight criteria — ranging performance, beam quality, environmental sensors, firmware reliability, triggering a range, ranging without pointing your weapon, ballistic software and support. The Sightlok RF-1 and Sig KILO2200 combination wins six, environmental sensors are a tie, and the Tango Fire 4000 wins one.
Sig Sauer Remotely Disabling BDX Rangefinders & Scopes – Our Argument with Nick Vitalbo, Applied Ballistics CEO
The team at Sightlok are big fans of the Sig Sauer BDX platform, and actively use it. Applied Ballistics, the company, is the main developer of Sig BDX platform. Needless to say Applied Ballistics is an awesome company that builds awesome software. But that doesn’t mean there’s no room for improvement. And one area that needs changing is their policy of disabling Sig BDX devices remotely if the Sig app detects the end user is not running the latest firmware. This is something we’ve been very vocal about both publicly and privately with Sig and Applied Ballistics management. Applied Ballistics…
Sig WMLRF KILO WARP Rangefinder – Potentially Huge Implications
Sig Sauer’s much-anticipated weapon-mounted laser rangefinder (WMLRF), the KILO WARP, will be released soon. The KILO WARP uses the same engine and laser from the SIG KILO 10K and comes with the Applied Ballistics Elite (AB Elite) on board. Straight off the bat, one concern is the Bluetooth remote. Will there be delays introduced by the Bluetooth connection? Many prefer having a wired remote. Rumors suggest there will be 950nm and 1550nm versions, both available to civilians. The 1550nm version will cost around $10,000. The 950nm will be Bluetooth remote only while the 1550nm will also support wired remote, a…
Major Problems Discovered with Tango Fire4000 WMLRF
Should you buy a Tango Fire4000? Probably not. It has no built-in environmental sensors, a $130 Sig KILO2200 handheld outranges it, its excessive beam divergence can cause false readings near brush, two firmware bugs can lead to a wrong firing solution, Tango Innovations is moving its ballistic software to a cloud-based app, and owners report poor customer support.
Review of Sig KILO5K – Problems, Pros, and Cons
Problem #1: Sig Forcing Users to Update Firmware and Disabling BDX Scopes and Rangefinders if the User Declines, and these Firmware Updates Are Known to Brick Rangefinders. When you connect your BDX to the BDX app, Sig checks the version of your rangefinder firmware. If Sig has decided your firmware needs updating, the BDX app forces you to update your firmware and disables your BDX rangefinder (and occasionally your BDX scope as well) until you comply. What?! That’s right. The Sig BDX app remotely disables your rangefinder and your scope when it detects old firmware on your devices. Just plain…
Honest Sig KILO8K-ABS Review – List of Known Problems
Problem #1: Firmware updates can brick the KILO8K and Sig disables the unit if you don’t update the firmware. You’re heading out for a day of shooting, you connect to the App, and suddenly you’re forced to either update the firmware, or Sig disables the rangefinder. It’s mandatory update or your rangefinder stops working. This is a problem that many Sig users have reported. The forced updates have also been known to brick rangefinders, potentially disrupting a planned day of shooting or hunting trip. What we most object to is Sig disabling the devices until the firmware update is complete.…
