I have the trigger hooked to the riser itself. The only other variable is placement of the device and your hand. As long as the device is looking at the target from the same location every time and pointed at the same spot every time, while your hand starts at the same distance from the device every time, you'll be fine. I mark the ground where I stand and set up for consistency.

 

How high do you have yours? And weird I was basically doing everything you said besides the location of the mic and still had a lot of consistency issues… also even at 20yards the fps read from launch to 20yards was super off. No way my arrow looses 18fps in 20 yards.

 

Do you have any other objects placed in front of the radar that might be reflecting signals? We were told you basically can’t use it indoors because of this

 

Nothing blocking it and was outdoors. Maybe I’ll give them a call tomorrow and see what they say

 

How far was your target? And how did you angle the device to the target?

My target is almost always 80 yards away, and I angle slightly high to above noise from the ground. Sometimes the speeds it provides in the five yards just in front of the target are completely erroneous.

Usually the arrow doesn't cross the beam until 15+ yards in front of the device. If it hits interference or noise in that zone, it can't accurately estimate launch velocity.

Target was 20 yards away. Was really looking for fps at launch.

 

One other tip is to make sure your Lab Radar is setup to actually use the trigger. You can technically have the unit in ‘Doppler’ trigger mode even when the microphone is plugged in.

Under the ‘Trigger Source’ setting, you’ll want to make sure you have ‘Trigger’ selected.

This is what it sounds like to me.

 

I did have it set to trigger mode. Just so weird Would get a reading of 278 and next shot would be 250 and next shot would be 262. Might try Garmin instead.

 

It will function fine in Doppler trigger mode. The key is shooting close enough to the radar cone at launch. Or at least seemed to be for me. Set the velocity range to archery. Set the offset distance to 12". Use Doppler for the trigger, the microphone is not as reliable. Then stand with your bow right next to the unit being careful not to hit the unit with your hand or riser on the shot.

To aim the lab radar, at that distance you will want to use the notch at the top to line up with the top third of the target. At further distances I aim for the center.

If you are indoors, then a 20 yard range will give too much feedback. In windy environments where the radar is moving in the wind your results may be suspect.

The Labradar is pretty easy to use when you learn it

 

Interesting! This hasn’t been my experience at all.

I’ve had much more consistent results with the trigger. Typical standard deviations for a string are sub 0.3fps. With Doppler, I was all over the place.

I may have to revisit and do some more testing. It’d save folks 50 bucks on the crappy trigger!

 

But, yeah, to @Jasonsnightmare ’s point, 20 yards from the target simply might not be far enough. Might try backing it up to at least 40 or so.

 

I would agree with others.

where are the swings occurring? For example if you want a speed at 70, and the target is right at 70, you’ll have issues. I like at least ten yards between the distance I want the speed at and the target. So if I’m shooting for speed at 70, the target is at 80.

I usually have the lab radar to the side of me, roughly level with the arrow pointing at the target with the mic attached to the bow riser

 

It kind of depends.

I’ve had a couple of their triggers where I had to play around with the connectors a little bit to get them to trigger consistently.

One way you can test the trigger itself is just by arming the unit and tapping on the trigger. When the orange light flashes, that’s when it triggers.

It’s also possible that the drawing of the bow is triggering the unit. Something to watch out for. You can play with the sensitivity some to get it to not trigger on draw but consistently trigger at the shot.

I will say I’ve had nothing but good results with the JKL. It is a bit more sensitive, so I do turn down the sensitivity on my units.
