TargetTalk

First, I'm not an Olympic rifle shooter, I'm an NRA rifle silhouette shooter, and I train indoors with a scoped RWS Model 75 on an airgun, pull-sting-reset, biathlon target.... which duplicates silhouette shooting pretty darn well! But, my venerable airgun is 34 years old, and I worry about it going south.... I've looked at the biathlon lazer trainers, which would work well for me and would eliminate the pellet mess, but it's pricey! I have several target and silhouette rifles... is there a device that would fit on one that I could use against the biathlon electronic target? I'm not interested in the tracking and whatever, I just need a reactive target. I know it's a long shot, but I would appreciate any feedback (I'll repost this on the biathlon section, too.).
