for a few years i was using the valentine one + bt module + yav1 phone app.
it performed well but was getting to be a pain in the ass to use.
last year i switched to the uniden r3.
it is a superb performer, that's also easy to setup and use.
currently the best windscreen mount detector sold in nz, with maybe the radenso pro m.
a big bonus is that uniden have finally made software updates readily available to users.
as mentioned above, the uniden r7 will be out in april.
big bonus is valentine style arrows updated for the 21st century.
it will be more expensive than the r3 (currently $899nzd/399usd), us rrp will be $599. nz ???
