We chose A+T for the complete refit of our TP52. I found their products are not only industry-leading in performance, but incredibly robust and support numerous buses and interfaces. More than that, we were particularly impressed by A+T's outstanding service and support.

Rachel Oliver, Osprey Technical
We have had a fantastic experience with A+T Instruments since we first installed them. Their after-sales service is fantastic and they'll always be my first port of call for instruments in the future.
Mike Edmonds, Captain of SY Ningaloo
After a major refit over the winter we’re aiming higher in 2025 - and electronics are a big focus. We installed the A+T ATP processor last year. And then compared the B&G 40/40s, Nemesis and A+T BFDs. We chose the A+T and haven’t looked back. The BFDs offer incredible clarity, mechanical durability and zero lag. Running a 6-field layout, the readability in Palma’s bright sun was flawless.
