It’s not the Bullseye system that’s the performance bottleneck but the lousy antenna in one’s tablet or smart phone that needs to receive a signal over the distance being shot.
I shared a Gen 1 system with a mate for a few years and the staple diet was 1k yards. As the battery’s performance started to wane, we began experiencing reception issues and had to start repositioning our tablets to reconnect. The problem was solved by replacing the rubber duck antenna with a 2.4 GHz Yagi, i.e. still using the antenna’s base which is actually an amplifier as well.
After my mate stopped LR, I no longer had access to the Bullseye system and had to find an alternative solution. The current set-up comprises a Reolink Eco Webcam with USB power connection and an external antenna (SMA) One Yagi antenna is connected to the camera which has built in batteries so one doesn’t even need a power bank.
Reception is another Yagi antenna to a USB powered mini router with a power bank (also useful for supplementary power to the tablets during a day’s worth of shooting) at the shooting point which makes life far easier for the tablets, since they only need to connect to the local WiFi network.
Excellent reception and optical performance out to 950m (max range tested so far) without an amplifier, thanks to the directional Yagis. The camera is out of the line of fire with adequate resolution when using the digital zoom.
The downside: No software that shows where the last shot went, so I have to take a screen shot after every shot (easy with the Reolink software which includes the date and time) , record the time in my reloading log book, and analyze the target for groups later.
Total cost: Approx. 150€/130£ incl. three tripods for the camera and the Yagis.
