The brand new Nash Siren R3+ Alarms are the reworked version of the previous ever famous R3's, They were the first alarm on the market with speed sensing technology which fully prevents fake bleeps and gives you out and out confidence in your bite detection. Re-worked now with modern technology allowing you to interchange your LED between 5 different colours (Red, Blue, Green, White and Purple) and now with the new MMCX connection which is featured on the Nash R4's allows them to connect to the siren Night Glo Bobbins and the brand Swing Arm illuminated indicators.

The Nash Siren R3+ bite indicator is a one-of-a-kind bite alarm with Intelligent Sensing. This alarm has a roller wheel like a normal alarm but whereas normal bite alarms sound every time the magnet in the roller passes the reed switch. The roller on the R3 alarm detects the speed at which the line moves, so if it detects different speeds it sounds but if it's just a slow gentle movement it won't even if the wheel fully rotates. That means an end to irritating false detection that other bite alarms suffer with. How many times do you sit there get a bleep and say, it's just wind? Once you get used to using the R3+ alarm and get to trust it you won't say that. The times I've sat there and had one bleep and reeled in to find out I'd been done. There are three sensitivity settings, One bleep on the setting is for the lowest on the speed sensing mode. This setting is for when the weather is terrible or it is a good choice when using them on the river. Two bleeps is what I use mine on, this is still on the sensing mode but it's more sensitive than one but will still eliminate a lot of false indications. Three bleeps turn the alarm to a standard roller alarm for use on runs waters but to be honest mine always stays on setting two and I've learnt NOT to ignore the R3+ Bite alarm.
