The Alpha will track DC50's and the Astro 430 will track the TT collars, just thought I'd mention it in case you ran across a deal on some 50's. You have to "re pair" the 50's to an alpha or the 430 as they can't be tracked by the old 320's and the Alpha or the 430 at the same time, it is actually a different frequency.
Thank you sir, no I did not realize that. Sooo.....I did buy this Alpha and tt15 and I’m wondering if I need to/should get all 15s now or if I could go a little “cheaper” on collars with ones that don’t train?? I feel like the training aspect would come in handy for things other than trashing...I figure I can teach them toning if they can’t hear me hooping them back? Or feel like ignoring me lol. I feel like it’d be good for grown dogs and any youngsters in the future. I played around with this thing a little bit and it seems pretty nifty.
