Where are you located? Ideally you would want to test against the hardest guns in use in your area, which are unfortunately typically the most expensive. There might be a tester near you who can help you out.Not yet. Hopefully I can soon!
What would be a good cheap LiDAR gun to purchase for testing?
I'm not sure about what's in use in your area in terms of laser, but I'm sure we have members that could help you find out that information. Also check the active testers page at https://www.rdforum.org/index.php?threads/94684/Calgary Canada
The installer sounds maybe a bit misinformed about the requirements/recommendations of a setup like this. As mentioned above, moving them up will likely yield better performance, and it definitely won't be too close to the Tx head.Hmmm.
The installer told me the Rx heads were placed here because otherwise they would be placed too near the TX head.
Perhaps they could be moved but not a good fit for this reason?
