Send them a letter telling them you want to do a TEST AND EVALUATION on their product for this web site. It's called T&E in the Law Enforcement field. If they bite, you get it for free to try and report back to us. And if your lucky, they will forget about it and it's yours FREE. Believe me it works. So far I've gotten, Gillie suits, scopes, range finders and lotsa other goodies for " T&E ". The trick is to get it just before the season starts, cause by the time they ask for it back, the season will be done
It looks cool, but if I remember my physics, magnets loose their strength with time, which would cause an imbalance in the field, which would lead to tuning issues. Also, unless your bow has absolutely perfectly level nock travel (most do not)the arrow will flex at the release, Upwards for release users and to the side for finger shooters. Wonder if this field is strong enough to not cause pretty eratic arrow flight, and the changes with time would be a tuning nightmare.
