Great line at economic price.
April 7, 2020
I use the Hi-Seas product for many, many years in different type of characteristics. From line for spearguns in 300lbs of resistant to little tackle fishing in a small river. The brand are synonym of HI quality. The Grand Slam 20lbs is not a exception. For spinning in the surf are the best.
ProsQuality and price.

This was a free add on to my order. I thought it would be okay, turned out better than I expected. I used it to top shot my rock fish reels and it has been performing well. Lingcod is a little tough on it though, seems to get nicks a little easier than the Seagard I usually use.
ProsHolds the knots well

January 20, 2016
Was given a spool of this line for free with my purchase of a reel from tackle direct. I dont use mono very often, but this stuff is ok, especially for being free! I will throw it in my bag and use it for backup if i ever get spooled or need a light leader for something.
ProsFree Decent quality mono
ConsI hardly ever use mono Line diameter vs pound test
By James
Hi-Seas is actually good line.
January 11, 2016
I am used to using braid with either flouro or a shock leader, but sometimes I do use mono when it calls for it. Most times I will use mono for just party boat fishing and like the line to be as light as possible without sacrificing power and abrasion resistance, especially since I mainly target Grouper in the GoM. This line is actually pretty nice. I never really gave it much of an after thought as I saw some on TV being pushed, but after using it and spooling it on a modified Accurate DPX2-500, I found the line to be pretty good in Diameter, the breaking strength seemed to be higher than stated, and it easy not as stiff as some of the other lines out there. To get the job done, this is actually a decent or dare I say it, good line. When I do use Mono, I usually use either Seaguar Senshi, Momoi Daimond, rarely, H/C, and Maxima. I would rank this line near the top tier.
ProsStrong Abrasion Resistance ABS looks to be stronger than stated
ConsNone really, wish it could be a tad thinner in diam.

Used the Hi seas Grand Slam on my fierce 4000 an it was awesome. Good casting line and super strong. I used the 15 pound clear and didn't have no problem with the casting or when I hooked up with that 5 pound sheep head. It gave a good tug but really held on when I was reeling it up to the top of the peer. I highly recommend buying this product.

Memory Problems
January 20, 2014

I like this mono line as I use it for spot, kingfish, croakers and other smaller saltwater fish. Also use it for perch and catfish fishing on the Delaware river. Typically, I notice that mono line wears out a lot faster when fishing in saltwater. However, I haven't notice the same wear progression with this line. To be specific, it wears but the line is much tougher. I would purchase this line again.

Excellent Quality At A Great Price Equals A Grand Slam!
September 17, 2013
I got this line free as a promotional offer by Tackle Direct! One of the many reasons I choose to buy from Tackle Direct; their great promotional offers. I spooled up my workhorse inshore reel, my Jigmaster 500, and headed out on a 1/2 day trip out of Newport for rockfish. The line offers extra durability and is extremely abrasive resistant. Line memory is minimal with excellent knot strength. Not only would I jump at any offer that includes a free spool of Hi-Seas Grand Slam fishing line but after trying this high performance line I will be purchasing it because of its exceptional value!

Received a free 300 yard spool last summer with my purchase of a Penn Sargus from Tackle Direct. I wasn't expecting much since it was given as a promotion, but after I tried and was unhappy with a different brand, I gave it a shot. Casts well for mono, strong, resists abrassions pretty well and has good stretch. Landed two mid 40" Stripers with it, which were over the 15lb rating. I was impressed and now use their other brand of lines and leaders.

I have found nothing to complain about while using any Hi-Seas products.

Now it is first choice when buying new line.
