The Mag Head Range

The 32x10mm MKI Mag heads were the very first “Bobbins” with a built in Internal Line Clip mechanism ever made - way back in 2004; it now seems most of the fishing tackle industry has copied the idea!  Which sadly can only be expected, as true innovation is very rare things when it comes to fishing tackle.

 This large comprehensive range below have been designed and tweaked over many years to provide reliable Indicator Head options to cover all eventualities. All utilise a standard 2BA thread for fitment, and all are capable of Isotope fitment inside a central chamber.

32mm x 1/2" Mag Heads in 11 colour options 

 Yellow, Black, Fluro Green, Fluro Pink, Emerald Green, Ruby Red, Iron Brew, White, Fluro Orange, Purple & Blue


(Weight - Approx. 5 Gram)


Price £6.50 Each



Custom 32mm x 1/2" MKII Style Mag Heads

32mm x 1/2" MKI Mag Heads can be made with Twin Line Clips built into them for just a little extra cost (Just the same as "Tall Boys" and MKII Mag Heads have fitted as standard) This then allows them to be used “weightless” for Slack lining, but in a totally safe way – as the Line is not gripped in anyway. By placing the line through the Twin Line Clips in a “Shaped configuration, this allows what ever Indicator the Mag Head is fitted on to to be set weightless (Tight line at the Reel Side and Slack line at the Alarms side) 



HS Mag Heads

32 x 15mm size in 7 colour options 

Black, Red Green, Blue, Crystal, White & Yellow

32 x 20mm size in 12 colour options 

Black, Fluro Yellow, Blue, Emerald Green, Fluro Green, Fluro Orange, Iron Brew, Fluro Pink, White, Crystal, Ruby Red & Purple

Larger versions of  Mag Heads made in two sizes as standard, both with a much stronger Line Clip mechanism fitted - which are 75% stronger when compared to a 32x10mm Mag Heads line clip mechanism, which is fully self adjusting and able to cope with Mono or Braid with ease, with a built in cleaning/lubrication chamber to guarantee a faultless service over many years.

MKII Mag  Heads




As requested by many customers the MKII Mag Heads are back, after being up-graded for 2016 – with larger diameter Crystal Inner Bodies, enhancing the Isotope positioning even more.

When 15mm long MPS White Isotopes are fitted, they literally light up the Head section “Like a Light Bulb” regardless of what colour Shroud is fitted – even with Black Shrouds fitted.  Fitted with a twin Line Clip mechanisms allowing the ability to set “weightless” for Slack Lining, by simply placing the line through the twin Clips in a “S” shape configuration. When set this way, the Indicator will hold position even thou the line is not being not gripped in anyway
